91 <!-- INTRODUCTION -->
92 <h2 id="intro">Introduction</h2>
94 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
95 a single database. To accomplish the latter you'll need a properly set up
96 MySQL user who can read/write only the desired database. It's up to you to
97 look up the appropriate part in the MySQL manual.
98 </p>
100 <h3>Currently phpMyAdmin can:</h3>
102 <ul><li>browse and drop databases, tables, views, columns and indexes</li>
103 <li>create, copy, drop, rename and alter databases, tables, columns and
104 indexes</li>
105 <li>maintenance server, databases and tables, with proposals on server
106 configuration</li>
107 <li>execute, edit and bookmark any
108 <abbr title="structured query language">SQL</abbr>-statement, even
109 batch-queries</li>
110 <li>load text files into tables</li>
111 <li>create<a href="#footnote_1"><sup>1</sup></a> and read dumps of tables
112 </li>

150 <h4>A word about users:</h4>
151 <p> Many people have difficulty
152 understanding the concept of user management with regards to phpMyAdmin. When
153 a user logs in to phpMyAdmin, that username and password are passed directly
154 to MySQL. phpMyAdmin does no account management on its own (other than
155 allowing one to manipulate the MySQL user account information); all users
156 must be valid MySQL users.</p>
158 <p class="footnote" id="footnote_1">
159 <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
160 dumps and <abbr title="comma separated values">CSV</abbr> exports if you use
161 PHP with Zlib support (<tt>--with-zlib</tt>) and/or Bzip2 support
162 (<tt>--with-bz2</tt>). Proper support may also need changes in
163 <tt>php.ini</tt>.</p>
165 <!-- INSTALLATION -->

173 </ol>
175 <p class="important">
176 phpMyAdmin does not apply any special security methods to the MySQL database
177 server. It is still the system administrator's job to grant permissions on
178 the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
179 be used for this.
180 </p>
182 <p class="important">
183 Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
184 if you are on a <acronym title="Apple Macintosh">Mac</acronym>
185 <abbr title="operating system">OS</abbr> version before
186 <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
187 <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
188 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
189 before uploading them to your server, as PHP seems not to like
190 <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
191 (&quot;<tt>\r</tt>&quot;).</p>
193 <h3 id="quick_install">Quick Install</h3>
194 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
195 Downloads page. Some kits contain only the English messages,
196 others contain all languages in UTF-8 format (this should be fine
197 in most situations), others contain all
198 languages and all character sets. We'll assume you chose a kit whose
199 name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
200 </li>
201 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
202 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
203 document root. If you don't have direct access to your document root,
204 put the files in a directory on your local machine, and, after step 4,
205 transfer the directory on your web server using, for example, ftp.</li>
206 <li>Ensure that all the scripts have the appropriate owner (if PHP is
207 running in safe mode, having some scripts with an owner different
208 from the owner of other scripts will be a
209 problem). See <a href="#faq4_2">
210 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
211 <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
212 1.26</a> for suggestions.</li>
213 <li>Now you must configure your installation. There are two methods that
214 can be used. Traditionally, users have hand-edited a copy of
215 <tt>config.inc.php</tt>, but now a wizard-style setup script is
216 provided for those who prefer a graphical installation. Creating a
217 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
218 <ul><li>To manually create the file, simply use your text editor to
219 create the file <tt>config.inc.php</tt> (you can copy
220 <tt>config.sample.inc.php</tt> to get minimal configuration
221 file) in the main (top-level) phpMyAdmin directory (the one
222 that contains <tt>index.php</tt>). phpMyAdmin first loads
223 <tt>libraries/config.default.php</tt> and then overrides those
224 values with anything found in <tt>config.inc.php</tt>. If the
225 default value is okay for a particular setting, there is no
226 need to include it in <tt>config.inc.php</tt>. You'll need a
227 few directives to get going, a simple configuration may look
228 like this:
229 <pre>
230 &lt;?php
231 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
233 $i=0;
234 $i++;
235 $cfg['Servers'][$i]['auth_type'] = 'cookie';
236 ?&gt;
237 </pre>
238 Or, if you prefer to not be prompted every time you log in:
239 <pre>
240 &lt;?php
242 $i=0;
243 $i++;
244 $cfg['Servers'][$i]['user'] = 'root';
245 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
246 $cfg['Servers'][$i]['auth_type'] = 'config';
247 ?&gt;
248 </pre>
249 For a full explanation of possible configuration values, see the
250 <a href="#config">Configuration Section</a> of this document.</li>
251 <li id="setup_script">Instead of manually editing
252 <tt>config.inc.php</tt>, you can use the
253 <a href="setup/">Setup Script</a>. First you must
254 manually create a folder <tt>config</tt> in the phpMyAdmin
255 directory. This is a security measure. On a Linux/Unix system you
256 can use the following commands:
257 <pre>
258 cd phpMyAdmin
259 mkdir config # create directory for saving
260 chmod o+rw config # give it world writable permissions
261 </pre>
262 And to edit an existing configuration, copy it over first:
263 <pre>
264 cp config.inc.php config/ # copy current configuration for editing
265 chmod o+w config/config.inc.php # give it world writable permissions
266 </pre>
267 On other platforms, simply create the folder and ensure that your
268 web server has read and write access to it. <a href="#faq1_26">FAQ
269 1.26</a> can help with this.<br /><br />
271 Next, open <tt><a href="setup/">setup/</a>
272 </tt>in your browser. Note that <strong>changes are not saved to
273 disk until explicitly choose <tt>Save</tt></strong> from the
274 <i>Configuration</i> area of the screen. Normally the script saves
275 the new config.inc.php to the <tt>config/</tt> directory, but if
276 the webserver does not have the proper permissions you may see the
277 error "Cannot load or save configuration." Ensure that the <tt>
278 config/</tt> directory exists and has the proper permissions -
279 or use the <tt>Download</tt> link to save the config file locally
280 and upload (via FTP or some similar means) to the proper location.<br /><br />
282 Once the file has been saved, it must be moved out of the <tt>
283 config/</tt> directory and the permissions must be reset, again
284 as a security measure:
285 <pre>
286 mv config/config.inc.php . # move file to current directory
287 chmod o-rw config.inc.php # remove world read and write permissions
288 rm -rf config # remove not needed directory
289 </pre>
290 Now the file is ready to be used. You can choose to review or edit
291 the file with your favorite editor, if you prefer to set some
292 advanced options which the setup script does not provide.</li></ul></li>
293 <li>If you are using the
294 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
295 protect the phpMyAdmin installation directory because using
296 config does not require a user to
297 enter a password to access the phpMyAdmin installation. Use of an alternate
298 authentication method is recommended, for example with
299 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
300 <tt>auth_type</tt> cookie or http. See the
301 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
302 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
303 information, especially <a href="#faq4_4">
304 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
305 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
306 in your browser. phpMyAdmin should now display a welcome screen
307 and your databases, or a login dialog if using
308 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
309 authentication mode.</li>
310 <li>You should deny access to the <tt>./libraries</tt> and
311 <tt>./setup/lib</tt> subfolders in your webserver configuration. For
312 Apache you can use supplied .htaccess file in that folder, for other
313 webservers, you should configure this yourself. Such configuration
314 prevents from possible path exposure and cross side scripting
315 vulnerabilities that might happen to be found in that code.</li>
316 <li>
317 It is generally good idea to protect public phpMyAdmin installation
318 against access by robots as they usually can not do anything good
319 there. You can do this using <code>robots.txt</code> file in root of
320 your webserver or limit access by web server configuration. You can
321 find example <code>.htaccess</code> file which can help you achieve
322 this in <code>contrib</code> directory in phpMyAdmin.
323 </li>
324 </ol>
326 <h3 id="linked-tables">phpMyAdmin configuration storage</h3>
328 <p> For a whole set of new features (bookmarks, comments,
329 <abbr title="structured query language">SQL</abbr>-history,
330 tracking mechanism,
331 <abbr title="Portable Document Format">PDF</abbr>-generation, column contents
332 transformation, etc.) you need to create a set of special tables. Those
333 tables can be located in your own database, or in a central database for a
334 multi-user installation (this database would then be accessed by the
335 controluser, so no other user should have rights to it).</p>
337 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
338 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
339 special attention to <a href="#faq1_23">
340 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
342 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
343 or newer, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>
344 and then create new tables by importing <i>./scripts/create_tables.sql</i>.</p>
346 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
347 that you may need special (administrator) privileges to create the database
348 and tables, and that the script may need some tuning, depending on the
349 database name.</p>
351 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
352 should specify the table names in your <i>./config.inc.php</i> file. The
353 directives used for that can be found in the <a href="#config">Configuration
354 section</a>. You will also need to have a controluser with the proper rights
355 to those tables (see section <a href="#authentication_modes">Using
356 authentication modes</a> below).</p>
358 <h3 id="upgrading">Upgrading from an older version</h3>
360 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
361 unpacked one. Configuration files from old versions may
362 require some tweaking as some options have been changed or removed; in
363 particular, the definition of <tt>$cfg['AttributeTypes']</tt> has changed
364 so you better remove it from your file and just use the default one.
365 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
366 statement that you might find near the end of your configuration file.</p>
368 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
369 over <tt>config.inc.php</tt> because the default configuration file
370 is version-specific.</p>
372 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
373 version 5.x or newer and if you use the phpMyAdmin configuration storage,
374 you should run the SQL script found in
375 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
377 <h3 id="authentication_modes">Using authentication modes</h3>
379 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
380 authentication modes are recommended in a <b>multi-user environment</b>
381 where you want to give users access to their own database and don't want
382 them to play around with others.<br />
383 Nevertheless be aware that MS Internet Explorer seems to be really buggy
384 about cookies, at least till version 6.<br />
385 Even in a <b>single-user environment</b>, you might prefer to use
386 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
387 that your user/password pair are not in clear in the configuration file.
388 </li>
390 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
391 authentication modes are more secure: the MySQL login information does
392 not need to be set in the phpMyAdmin configuration file (except possibly
393 for the <a href="#controluser">controluser</a>).<br />
394 However, keep in mind that the password travels in plain text, unless
395 you are using the HTTPS protocol.<br />
396 In cookie mode, the password is stored, encrypted with the blowfish
397 algorithm, in a temporary cookie.</li>
399 <li id="pmausr">Note: this section is only applicable if
400 your MySQL server is running with <tt>--skip-show-database</tt>.<br /><br />
402 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
403 modes, phpMyAdmin needs a controluser that has <b>only</b> the
404 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
405 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
406 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
407 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
408 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
409 file under the
410 <tt><a href="#cfg_Servers_controluser" class="configrule">
411 $cfg['Servers'][$i]['controluser']</a></tt> and
412 <tt><a href="#cfg_Servers_controlpass" class="configrule">
413 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
414 The following example assumes you want to use <tt>pma</tt> as the
415 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
416 only an example: use something else in your file!</b> Input these
417 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
418 client.<br />
419 Of course you have to replace <tt>localhost</tt> with the webserver's host
420 if it's not the same as the MySQL server's one.
422 <pre>
423 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
424 GRANT SELECT (
425 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
426 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
427 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
428 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
429 Execute_priv, Repl_slave_priv, Repl_client_priv
430 ) ON mysql.user TO 'pma'@'localhost';
431 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
432 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
433 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
434 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
436 If you want to use the many new relation and bookmark features:
438 <pre>
439 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
440 </pre>
442 (this of course requires that your <a href="#linked-tables">phpMyAdmin
443 configuration storage</a> be set up).
444 <br /></li>
446 <li>Then each of the <i>true</i> users should be granted a set of privileges
447 on a set of particular databases. Normally you shouldn't give global
448 privileges to an ordinary user, unless you understand the impact of those
449 privileges (for example, you are creating a superuser).<br />
450 For example, to grant the user <i>real_user</i> with all privileges on
451 the database <i>user_base</i>:<br />
453 <pre>

465 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>
467 <ul><li>Uses <abbr title="HyperText Transfer Protocol">HTTP</abbr> Basic authentication
468 method and allows you to log in as any valid MySQL user.</li>

482 mode.</li>
483 </ul>
485 <h4>'cookie' authentication mode</h4>
487 <ul><li>You can use this method as a replacement for the
488 <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
489 (for example, if you're running
490 <abbr title="Internet Information Services">IIS</abbr>).</li>
491 <li>Obviously, the user must enable cookies in the browser, but this is
492 now a requirement for all authentication modes.</li>
493 <li>With this mode, the user can truly log out of phpMyAdmin and log in back
494 with the same username.</li>
495 <li>If you want to log in to arbitrary server see
496 <a href="#AllowArbitraryServer" class="configrule">
497 $cfg['AllowArbitraryServer']</a> directive.</li>
498 <li>As mentioned in the <a href="#require">requirements</a> section, having
499 the <tt>mcrypt</tt> extension will speed up access considerably, but is
500 not required.</li>
501 </ul>
503 <h4>'signon' authentication mode</h4>
505 <ul><li>This mode is a convenient way of using credentials from another
506 application to authenticate to phpMyAdmin.</li>
507 <li>The other application has to store login information into
508 session data.</li>
509 <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
510 section.</li>
511 </ul>
512 <h4>'config' authentication mode</h4>
514 <ul><li>This mode is the less secure one because it requires you to fill the
515 <a href="#servers_user" class="configrule">
516 $cfg['Servers'][$i]['user']</a> and
517 <a href="#servers_user" class="configrule">
518 $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
519 can read your config.inc.php can discover your username and password).
520 <br />
521 But you don't need to setup a &quot;controluser&quot; here: using the
522 <a href="#servers_only_db" class="configrule">
523 $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
524 <li>In the <a href="#faqmultiuser">
525 <abbr title="Internet service provider">ISP</abbr>
526 <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
527 is an entry explaining how to protect your configuration file.</li>
528 <li>For additional security in this mode, you may wish to consider the Host
529 authentication
530 <a href="#servers_allowdeny_order" class="configrule">
531 $cfg['Servers'][$i]['AllowDeny']['order']</a> and
532 <a href="#servers_allowdeny_rules" class="configrule">
533 $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
534 directives.</li>
535 <li>Unlike cookie and http, does not require a user to log in when first
536 loading the phpMyAdmin site. This is by design but could allow any
537 user to access your installation. Use of some restriction method is
538 suggested, perhaps a <a href="#glossary">.htaccess</a> file with the
539 HTTP-AUTH directive or disallowing incoming HTTP requests at
540 one&#8217;s router or firewall will suffice (both of which
541 are beyond the scope of this manual but easily searchable with Google).</li>
542 </ul>
543 <h4 id="swekey">Swekey authentication</h4>
545 The Swekey is a low cost authentication USB key that can be used in
546 web applications.<br /><br />
547 When Swekey authentication is activated, phpMyAdmin requires the
548 users's Swekey to be plugged before entering the login page (currently
549 supported for cookie authentication mode only). Swekey Authentication is
550 disabled by default.<br /><br />
551 To enable it, add the following line to <tt>config.inc.php</tt>:
552 </p>
553 <pre>
554 $cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';
555 </pre>
557 You then have to create the <tt>swekey.conf</tt> file that will associate
558 each user with their Swekey Id. It is important to place this file outside
559 of your web server's document root (in the example, it is located in <tt>/etc</tt>). A self documented sample file is provided
560 in the <tt>contrib</tt> directory. Feel free to use it with your own
561 users' information.<br /><br />
562 If you want to purchase a Swekey please visit
563 <a href="http://phpmyadmin.net/auth_key">http://phpmyadmin.net/auth_key</a>
564 since this link provides funding for phpMyAdmin.

594 Don&#8217;t forget the trailing slash at the end.<br /><br />
596 Starting with version 2.3.0, it is advisable to try leaving this
597 blank. In most cases phpMyAdmin automatically detects the proper
598 setting. Users of port forwarding will need to set PmaAbsoluteUri (<a

600 A good test is to browse a table, edit a row and save it. There should
601 be an error message if phpMyAdmin is having trouble auto&#8211;detecting
602 the correct value. If you get an error that this must be set or if

643 no maximum length for this secret.<br /><br />
645 Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
646 makes a bit weaker security as this generated secret is stored in

648 cookie.</dd>
650 <dt id="cfg_Servers">$cfg['Servers'] array</dt>

842 need to specify all other databases. Use:
843 <tt>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</tt>

996 Since release 2.3.0 you can store comments to describe each column for

998 <br /><br />
1000 Starting with release 2.5.0, comments are consequently used on the table
1001 property pages and table browse view, showing up as tool-tips above the
1002 column name (properties page) or embedded within the header of table in
1003 browse view. They can also be shown in a table dump. Please see the
1004 relevant configuration directives later on.<br /><br />
1006 Also new in release 2.5.0 is a MIME-transformation system which is also
1007 based on the following table structure. See <a href="#transformations">
1008 Transformations</a> for further information. To use the
1009 MIME-transformation system, your column_info table has to have the three
1010 new columns 'mimetype', 'transformation', 'transformation_options'.
1011 <br /><br />
1013 To allow the usage of this functionality:
1014 <ul><li>set up <a href="#pmadb">pmadb</a> and the phpMyAdmin configuration storage</li>

1039 all queries you entered manually into the phpMyAdmin interface. If you
1040 don't want to use a table-based history, you can use the JavaScript-based
1041 history. Using that, all your history items are deleted when closing the
1042 window.<br /><br />
1044 Using
1045 <a href="#cfg_QueryHistoryMax" class="configrule">$cfg['QueryHistoryMax']</a>
1046 you can specify an amount of history items you want to have on hold. On
1047 every login, this list gets cut to the maximum amount.<br /><br />

1065 Since release 3.5.0 you can show recently used tables in the left navigation frame.
1066 It helps you to jump across table directly, without the need to select the database,
1067 and then select the table. Using
1068 <a href="#cfg_LeftRecentTable" class="configrule">$cfg['LeftRecentTable']</a>
1069 you can configure the maximum number of recent tables shown. When you select a table
1070 from the list, it will jump to the page specified in
1071 <a href="#cfg_LeftDefaultTabTable" class="configrule">$cfg['LeftDefaultTabTable']</a>.<br/><br/>
1073 Without configuring the storage, you can still access the recently used tables,

1107 Since release 3.3.x a tracking mechanism is available.
1108 It helps you to track every <abbr title="structured query language">SQL</abbr> command which
1109 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1110 and data definition statements. After enabling it you can create versions of tables.
1111 <br/><br/>
1112 The creation of a version has two effects:
1114 <ul>
1115 <li>phpMyAdmin saves a snapshot of the table, including structure and indexes.</li>
1116 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1117 </ul>
1119 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1120 For the report you can use filters, for example you can get a list of statements within a date range.
1121 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1122 In addition you can export the (filtered) report to a file or to a temporary database.
1123 <br/><br/>
1125 To allow the usage of this functionality:

1362 list of servers without logging in.<br />
1363 If you have only one server configured, <tt>$cfg['ServerDefault']</tt>
1364 MUST be set to that server.</dd>
1366 <dt id="cfg_AjaxEnable">$cfg['AjaxEnable'] boolean</dt>
1367 <dd>Defines whether to refresh only parts of certain pages using Ajax
1368 techniques. Applies only where a non-Ajax behavior is possible;
1369 for example, the Designer feature is Ajax-only so this directive
1370 does not apply to it.</dd>
1372 <dt id="cfg_VersionCheck">$cfg['VersionCheck'] boolean</dt>
1373 <dd>Enables check for latest versions using javascript on main phpMyAdmin
1374 page.</dd>

1377 <dd>The maximum number of database names to be displayed in the
1378 navigation frame and the database list.</dd>
1380 <dt id="cfg_MaxTableList">$cfg['MaxTableList'] integer</dt>
1381 <dd>The maximum number of table names to be displayed in the

1386 <dd>Whether to show the hints or not (for example, hints when hovering table header)</dd>
1388 <dt id="cfg_MaxCharactersInDisplayedSQL">$cfg['MaxCharactersInDisplayedSQL'] integer</dt>
1389 <dd>The maximum number of characters when a SQL query is displayed. The
1390 default limit of 1000 should be correct to avoid the display of tons
1391 of hexadecimal codes that represent BLOBs, but some users have real
1392 SQL queries that are longer than 1000 characters. Also, if a query's
1393 length exceeds this limit, this query is not saved in the history.</dd>
1395 <dt id="cfg_OBGzip">$cfg['OBGzip'] string/boolean</dt>
1396 <dd>Defines whether to use GZip output buffering for increased
1397 speed in <abbr title="HyperText Transfer Protocol">HTTP</abbr> transfers.<br />
1398 Set to true/false for enabling/disabling. When set to 'auto' (string),
1399 phpMyAdmin tries to enable output buffering and will automatically disable
1400 it if your browser has some problems with buffering. IE6 with a certain patch
1401 is known to cause data corruption when having enabled buffering.</dd>
1403 <dt id="cfg_PersistentConnections">$cfg['PersistentConnections'] boolean</dt>
1404 <dd>Whether <a href="http://php.net/manual/en/features.persistent-connections.php">persistent connections</a>
1405 should be used or not. Works with following extensions:

1414 <dt id="cfg_ExecTimeLimit">$cfg['ExecTimeLimit'] integer [number of seconds]</dt>
1415 <dd>Set the number of seconds a script is allowed to run. If seconds is set
1416 to zero, no time limit is imposed.<br />
1417 This setting is used while importing/exporting dump files and in the
1418 Synchronize feature but has no effect when PHP is running in safe mode.</dd>
1420 <dt id="cfg_SessionSavePath">$cfg['SessionSavePath'] string</dt>

1425 <dd>Set the number of bytes a script is allowed to allocate. If set
1426 to zero, no limit is imposed.<br />
1427 This setting is used while importing/exporting dump files and at some
1428 other places in phpMyAdmin so you definitely don't want to put here
1429 a too low value. It has no effect when PHP is running in safe mode.<br />
1430 You can also use any string as in php.ini, eg. '16M'. Ensure
1431 you don't omit the suffix (16 means 16 bytes!)</dd>
1433 <dt id="cfg_SkipLockedTables">$cfg['SkipLockedTables'] boolean</dt>
1434 <dd>Mark used tables and make it possible to show databases with locked

1438 <dd>Defines whether <abbr title="structured query language">SQL</abbr> queries
1439 generated by phpMyAdmin should be displayed or not.</dd>
1441 <dt id="cfg_AllowUserDropDatabase">$cfg['AllowUserDropDatabase'] boolean</dt>
1442 <dd>Defines whether normal users (non-administrator) are allowed to
1443 delete their own database or not. If set as FALSE, the link &quot;Drop
1444 Database&quot; will not be shown, and even a &quot;DROP DATABASE
1445 mydatabase&quot; will be rejected. Quite practical for
1446 <abbr title="Internet service provider">ISP</abbr>'s with many
1447 customers.<br />
1448 Please note that this limitation of SQL queries is not as strict as
1449 when using MySQL privileges. This is due to nature of SQL queries
1450 which might be quite complicated. So this choice should be viewed as
1451 help to avoid accidental dropping rather than strict privilege
1452 limitation.</dd>
1454 <dt id="cfg_Confirm">$cfg['Confirm'] boolean</dt>
1455 <dd>Whether a warning (&quot;Are your really sure...&quot;) should be

1464 </dd>
1466 <dt id="cfg_LoginCookieValidity">$cfg['LoginCookieValidity'] integer [number of seconds]</dt>
1467 <dd>Define how long is login cookie valid. Please note that php
1468 configuration option <a href="http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime">session.gc_maxlifetime</a>
1469 might limit session validity and if session is lost, login cookie is
1470 also invalidated. So it is a good idea to set <code>session.gc_maxlifetime</code>
1471 not lower than the value of $cfg['LoginCookieValidity'].</dd>
1473 <dt id="cfg_LoginCookieStore">$cfg['LoginCookieStore'] integer [number of seconds]</dt>
1474 <dd>Define how long login cookie should be stored in browser. Default 0
1475 means that it will be kept for existing session. This is recommended
1476 for not trusted environments.</dd>
1478 <dt id="cfg_LoginCookieDeleteAll">$cfg['LoginCookieDeleteAll'] boolean</dt>
1479 <dd>If enabled (default), logout deletes cookies for all servers,
1480 otherwise only for current one. Setting this to false makes it easy to

1482 them.</dd>
1484 <dt id="cfg_UseDbSearch">$cfg['UseDbSearch'] boolean</dt>
1485 <dd>Define whether the "search string inside database" is enabled or not.</dd>
1487 <dt id="cfg_IgnoreMultiSubmitErrors">$cfg['IgnoreMultiSubmitErrors'] boolean</dt>

1497 <span id="cfg_AllowArbitraryServer">$cfg['AllowArbitraryServer']</span> boolean</dt>
1498 <dd>If enabled, allows you to log in to arbitrary servers using cookie auth and permits to specify servers of your choice in the Synchronize dialog.
1499 <br /><br />
1501 <b>NOTE:</b> Please use this carefully, as this may allow users access to
1502 MySQL servers behind the firewall where your

1513 <dd>Defines whether to use a select-based menu and display only the current
1514 tables in the left frame (smaller page). Only in Non-Lightmode you can
1515 use the feature to display nested folders using
1516 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1517 </dd>
1519 <dt id="cfg_LeftFrameDBTree">$cfg['LeftFrameDBTree'] boolean</dt>
1520 <dd>In light mode, defines whether to display the names of databases (in the
1521 selector) using a tree, see also
1522 <a href="#cfg_LeftFrameDBSeparator" class="configrule">$cfg['LeftFrameDBSeparator']</a>.
1523 </dd>
1525 <dt id="cfg_LeftFrameDBSeparator">$cfg['LeftFrameDBSeparator']
1526 string or array</dt>
1527 <dd>The string used to separate the parts of the database name when showing
1528 them in a tree. Alternatively you can specify more strings in an array
1529 and all of them will be used as a separator.</dd>
1531 <dt id="cfg_LeftFrameTableSeparator">$cfg['LeftFrameTableSeparator'] string</dt>
1532 <dd>Defines a string to be used to nest table spaces. Defaults to '__'.
1533 This means if you have tables like 'first__second__third' this will be
1534 shown as a three-level hierarchy like: first &gt; second &gt; third.
1535 If set to FALSE or empty, the feature is disabled. NOTE: You should
1536 not use this separator at the beginning or end of a
1537 table name or multiple times after another without any other
1538 characters in between.</dd>
1540 <dt id="cfg_LeftFrameTableLevel">$cfg['LeftFrameTableLevel'] string</dt>
1541 <dd>Defines how many sublevels should be displayed when splitting

1549 <dd>Defines whether to display table comment as tool-tip in left frame or
1550 not.</dd>
1552 <dt id="cfg_ShowTooltipAliasDB">$cfg['ShowTooltipAliasDB'] boolean</dt>
1553 <dd>If tool-tips are enabled and a DB comment is set, this will flip the
1554 comment and the real name. That means that if you have a table called
1555 'user0001' and add the comment 'MyName' on it, you will see the name
1556 'MyName' used consequently in the left frame and the tool-tip shows
1557 the real name of the DB.</dd>
1559 <dt id="cfg_ShowTooltipAliasTB">$cfg['ShowTooltipAliasTB'] boolean/string</dt>
1560 <dd>Same as <a href="#cfg_ShowTooltipAliasDB" class="configrule">$cfg['ShowTooltipAliasDB']</a>, except this works for table names.
1562 When setting this to 'nested', the Alias of the Tablename is only used
1563 to split/nest the tables according to the
1564 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1565 directive. So only the folder is called like the Alias, the tablename itself
1566 stays the real tablename.</dd>
1568 <dt id="cfg_LeftDisplayLogo">$cfg['LeftDisplayLogo'] boolean</dt>
1569 <dd>Defines whether or not to display the phpMyAdmin logo at the top of the left frame.

1582 integer</dt>
1583 <dd>Defines the minimum number of tables to display a JavaScript filter box above the
1584 list of tables in the left frame.
1585 Defaults to <tt>30</tt>. To disable the filter completely some high number

1588 <dt id="cfg_LeftDisplayServers">$cfg['LeftDisplayServers'] boolean</dt>
1589 <dd>Defines whether or not to display a server choice at the top of the left frame.

1594 <dt id="cfg_DisplayDatabasesList">$cfg['DisplayDatabasesList'] boolean or text</dt>
1595 <dd>Defines whether to display database choice in light navigation frame as links
1596 instead of in a drop-down. Defaults to 'auto' - on main page list is
1597 shown, when database is selected, only drop down is displayed.</dd>
1599 <dt id="cfg_LeftDefaultTabTable">$cfg['LeftDefaultTabTable'] string</dt>
1600 <dd>Defines the tab displayed by default when clicking the small
1601 icon next to each table name in the navigation panel. Possible

1604 &quot;tbl_change.php&quot; or &quot;sql.php&quot;.</dd>
1606 <dt id="cfg_ShowStats">$cfg['ShowStats'] boolean</dt>
1607 <dd>Defines whether or not to display space usage and statistics about databases
1608 and tables.<br />
1609 Note that statistics requires at least MySQL 3.23.3 and that, at this
1610 date, MySQL doesn't return such information for Berkeley DB tables.</dd>
1612 <dt><span id="cfg_ShowServerInfo">$cfg['ShowServerInfo'] </span>boolean</dt>
1613 <dd>Defines whether to display detailed server information on main page.

1622 <dd>Defines whether to display the &quot;PHP information&quot; and
1623 &quot;Change password &quot; links and form for creating database or
1624 not at the starting main (right) frame. This setting
1625 does not check MySQL commands entered directly.<br /><br />
1627 Please note that to block the usage of phpinfo() in scripts, you
1628 have to put this in your <i>php.ini</i>:
1630 <pre>disable_functions = phpinfo()</pre>
1632 Also note that enabling the &quot;Change password &quot; link has no
1633 effect with &quot;config&quot; authentication mode: because of the
1634 hard coded password value in the configuration file, end users can't
1635 be allowed to change their passwords.</dd>
1637 <dt id="cfg_SuggestDBName">$cfg['SuggestDBName'] boolean</dt>

2091 This is needed to work around limitations of <tt>open_basedir</tt>
2092 for uploaded files, see
2093 <a href="#faq1_11"><abbr title="Frequently Asked Questions">FAQ</abbr>
2094 1.11</a>.
2095 <br /><br />
2097 If the directory where phpMyAdmin is installed is subject to an
2098 <tt>open_basedir</tt> restriction, you need to create a
2099 temporary directory in some directory accessible by the web
2100 server. However for security reasons, this directory should be outside
2101 the tree published by webserver. If you cannot avoid having this
2102 directory published by webserver, place at least an empty
2103 <tt>index.html</tt> file there, so that directory listing is not
2104 possible.
2105 <br /><br />
2107 This directory should have as strict permissions as possible as the only
2108 user required to access this directory is the one who runs the
2109 webserver. If you have root privileges, simply make this user owner of
2110 this directory and make it accessible only by it:
2111 <br /><br />
2113 <pre>
2114 chown www-data:www-data tmp
2115 chmod 700 tmp
2116 </pre>
2118 If you cannot change owner of the directory, you can achieve a similar
2119 setup using <abbr title="Access Control List">ACL</abbr>:
2121 <pre>
2122 chmod 700 tmp
2123 setfacl -m "g:www-data:rwx" tmp
2124 setfacl -d -m "g:www-data:rwx" tmp
2125 </pre>
2127 If neither of above works for you, you can still make the directory
2128 <code>chmod 777</code>, but it might impose risk of other users on
2129 system reading and writing data in this directory.

2180 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2181 or icon is always displayed on the left panel. If JavaScript is enabled in
2182 your browser, a click on this opens a distinct query window, which is
2183 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2184 changes to display a query box.<br /><br />
2186 The size of this query window can be customized with
2187 <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowHeight']</tt>
2188 - both integers for the size in pixels. Note that normally, those
2189 parameters will be modified in <tt>layout.inc.php</tt> for the
2190 theme you are using.<br /><br />
2192 If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
2193 from the results page (in the &quot;Showing Rows&quot; section)
2194 opens the query window and puts the current query
2195 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
2196 query in the right panel's query box.
2197 <br /><br />
2198 The usage of the JavaScript query window is recommended if you have a
2199 JavaScript enabled browser. Basic functions are used to exchange quite
2200 a few variables, so most 4th generation browsers should be capable to
2201 use that feature. It currently is only tested with Internet Explorer 6
2202 and Mozilla 1.x.
2203 <br /><br />
2204 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
2205 to a table, which has to be created by you (see <a
2206 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
2207 all your queries will be appended to the form, but only as long as
2208 your window is opened they remain saved.
2209 <br /><br />
2210 When using the JavaScript based query window, it will always get
2211 updated when you click on a new table/db to browse and will focus if
2212 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2213 the query window by checking the box "Do not overwrite this query from
2214 outside the window" below the query textarea. Then you can browse
2215 tables/databases in the background without losing the contents of the
2216 textarea, so this is especially useful when composing a query with
2217 tables you first have to look in. The checkbox will get automatically
2218 checked whenever you change the contents of the textarea. Please
2219 uncheck the button whenever you definitely want the query window to
2220 get updated even though you have made alterations.
2221 <br /><br />
2222 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
2223 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
2224 <br /><br />
2225 The query window also has a custom tabbed look to group the features.
2226 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
2227 default tab to be used when opening the query window. It can be set to
2228 either 'sql', 'files', 'history' or 'full'.</dd>

2412 <!-- TRANSFORMATIONS -->
2413 <h2 id="transformations">Transformations</h2>
2415 <ol><li><a href="#transformationsintro">Introduction</a></li>
2416 <li><a href="#transformationshowto">Usage</a></li>
2417 <li><a href="#transformationsfiles">File structure</a></li>
2418 </ol>
2420 <h3 id="transformationsintro">1. Introduction</h3>
2422 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2423 and the proper directives. Please see the <a href="#config">Configuration
2424 section</a> on how to do so.</p>
2426 <p> You can apply different transformations to the contents of each column. The
2427 transformation will take the content of each column and transform it with
2428 certain rules defined in the selected transformation.</p>
2430 <p> Say you have a column 'filename' which contains a filename. Normally you would
2431 see in phpMyAdmin only this filename. Using transformations you can transform
2432 that filename into a HTML link, so you can click inside of the phpMyAdmin
2433 structure on the column's link and will see the file displayed in a new browser
2434 window. Using transformation options you can also specify strings to
2435 append/prepend to a string or the format you want the output stored in.</p>
2437 <p> For a general overview of all available transformations and their options,
2438 you can consult your
2439 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2440 installation.</p>
2442 <p> For a tutorial on how to effectively use transformations, see our
2443 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2444 the official phpMyAdmin homepage.</p>
2446 <h3 id="transformationshowto">2. Usage</h3>
2448 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2449 clicking on the 'Structure' link for a table). There click on
2450 &quot;Change&quot; (or change icon) and there you will see three new
2451 fields at
2452 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2453 'Transformation options'.</p>
2455 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2456 that corresponds to the column's contents. Please note that
2457 transformations are inactive as long as no MIME-type is selected.</li>
2459 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2460 hopefully growing amount of pre-defined transformations. See below for information on
2461 how to build your own transformation.<br />
2463 There are global transformations and mimetype-bound transformations. Global transformations
2464 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2465 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2466 transformations which operate on the main mimetype (like 'image'), which will most likely
2467 take the subtype into regard, and those who only operate on a
2468 specific subtype (like 'image/jpeg').<br />
2470 You can use transformations on mimetypes for which the function was not defined for. There
2471 is no security check for you selected the right transformation, so take care of what the
2472 output will be like.</li>
2474 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2475 transform-function specific options here. Usually the transforms can operate with default
2476 options, but it is generally a good idea to look up the overview to see which options are
2477 necessary.<br />
2479 Much like the ENUM/SET-Fields, you have to split up several options using the format
2480 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2481 parsed as an array, leaving the first value the first element in the array, and so
2482 forth.<br />
2484 If you want to specify a MIME character set you can define it in the transformation_options.
2485 You have to put that outside of the pre-defined options of the specific mime-transform,
2486 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2487 for which you can specify 2 options and you want to append a character set, enter "'first
2488 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2489 the parameters: "'','','charset=us-ascii'".</li>
2490 </ul>
2492 <h3 id="transformationsfiles">3. File structure</h3>
2494 <p> All mimetypes and their transformations are defined through single files in
2495 the directory 'libraries/transformations/'.</p>
2497 <p> They are stored in files to ease up customization and easy adding of new
2498 transformations.</p>
2500 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2501 always work. It makes no sense to apply a transformation to a mimetype the
2502 transform-function doesn't know to handle.</p>
2504 <p> One can, however, use empty mime-types and global transformations which should work
2505 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2506 for, but pay attention to option usage as well as what the transformation does to your
2507 column.</p>
2509 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2510 any other transform function and provides some basic functions.</p>
2512 <p> There are 5 possible file names:</p>
2514 <ol><li>A mimetype+subtype transform:<br /><br />
2516 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2518 Please not that mimetype and subtype are separated via '_', which shall
2519 not be contained in their names. The transform function/filename may
2520 contain only characters which cause no problems in the file system as
2521 well as the PHP function naming convention.<br /><br />
2523 The transform function will the be called
2524 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2526 <b>Example:</b><br /><br />
2528 <tt>text_html__formatted.inc.php</tt><br />
2529 <tt>PMA_transform_text_html__formatted()</tt></li>
2531 <li>A mimetype (w/o subtype) transform:<br /><br />
2533 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2535 Please note that there are no single '_' characters.
2536 The transform function/filename may contain only characters which cause
2537 no problems in the file system as well as the PHP function naming
2538 convention.<br /><br />
2540 The transform function will the be called
2541 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2543 <b>Example:</b><br /><br />
2545 <tt>text__formatted.inc.php</tt><br />
2546 <tt>PMA_transform_text__formatted()</tt></li>
2548 <li>A mimetype+subtype without specific transform function<br /><br />
2550 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2552 Please note that there are no '__' characters in the filename. Do not
2553 use special characters in the filename causing problems with the file
2554 system.<br /><br />
2556 No transformation function is defined in the file itself.<br /><br />
2558 <b>Example:</b><br /><br />
2560 <tt>text_plain.inc.php</tt><br />
2561 (No function)</li>
2563 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2565 <tt>[mimetype].inc.php</tt><br /><br />
2567 Please note that there are no '_' characters in the filename. Do not use
2568 special characters in the filename causing problems with the file system.
2569 <br /><br />
2571 No transformation function is defined in the file itself.<br /><br />
2573 <b>Example:</b><br /><br />
2575 <tt>text.inc.php</tt><br />
2576 (No function)</li>
2578 <li>A global transform function with no specific mimetype<br /><br />
2580 <tt>global__[transform].inc.php</tt><br /><br />
2582 The transform function will the be called
2583 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2585 <b>Example:</b><br /><br />
2587 <tt>global__formatted</tt><br />
2588 <tt>PMA_transform_global__formatted()</tt></li>
2589 </ol>
2591 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2592 transform function.</p>
2594 <p> All filenames containing no '__' in themselves are not shown as valid transform
2595 functions in the dropdown.</p>
2597 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2598 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2599 without a transform function.</p>
2601 <p> To create a new transform function please see
2602 <tt>libraries/transformations/template_generator.sh</tt>.
2603 To create a new, empty mimetype please see
2604 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2606 <p> A transform function always gets passed three variables:</p>
2608 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2609 you want to transform.</li>
2610 <li><b>$options</b> - Contains any user-passed options to a transform function
2611 as an array.</li>
2612 <li><b>$meta</b> - Contains an object with information about your column.
2613 The data is drawn from the output of the
2614 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2615 function. This means, all object properties described on the
2616 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2617 available in this variable and can be used to transform a column accordingly
2618 to unsigned/zerofill/not_null/... properties.<br />
2619 The $meta-&gt;mimetype variable contains the original MIME-type of the
2620 column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2621 </ol>
2623 <p> Additionally you should also provide additional function to provide
2624 information about the transformation to the user. This function should
2625 have same name as transformation function just with appended
2626 <code>_info</code> suffix. This function accepts no parameters and returns
2627 array with information about the transformation. Currently following keys
2628 can be used:
2629 </p>
2630 <dl>
2631 <dt><code>info</code></dt>
2632 <dd>Long description of the transformation.</dd>
2633 </dl>

2791 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
2792 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2793 to take advantage of the new import features.</p>
2795 <p> The first things to check (or ask your host provider to check) are the
2796 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2797 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2798 All of these three settings limit the maximum size of data that can be
2799 submitted and handled by PHP. One user also said that post_max_size
2800 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2802 There exist several workarounds if your upload is too big or your
2803 hosting provider is unwilling to change the settings:</p>
2805 <ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
2806 feature. This allows one to
2807 upload a file to the server via scp, ftp, or your favorite file transfer
2808 method. PhpMyAdmin is then able to import the files from the temporary
2809 directory. More information is available in the <a href="#config">Configuration
2810 section</a> of this document.</li>
2811 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
2812 BigDump</a>) to split the files before uploading. We cannot support this
2813 or any third party applications, but are aware of users having success
2814 with it.</li>
2815 <li>If you have shell (command line) access, use MySQL to import the files
2816 directly. You can do this by issuing the &quot;source&quot; command from
2817 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>

2821 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2822 support?</a></h4>
2824 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2825 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
2826 connect to your MySQL server using PHP's classic
2827 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2828 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2829 is available in PHP 5.0. The latter one should be used unless you have a
2830 good reason not to do so.<br />
2831 When compiling PHP, we strongly recommend that you manually link the MySQL
2832 extension of your choice to a MySQL client library of at least the same
2833 minor version since the one that is bundled with some PHP distributions is
2834 rather old and might cause problems <a href="#faq1_17a">
2835 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.<br /><br />
2836 MariaDB is also supported (versions 5.1 and 5.2 were tested).

2844 <p> You tried to access MySQL with an old MySQL client library. The version of
2845 your MySQL client library can be checked in your phpinfo() output.
2846 In general, it should have at least the same minor version as your server
2847 - as mentioned in <a href="#faq1_17">
2848 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2850 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2851 changed the authentication hash and your PHP is trying to use the old method.
2852 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2853 with the proper client library to match your MySQL installation. Your
2854 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.

2878 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried

3089 </p>
3091 Suhosin configuration might lead to malfunction in some cases and it can
3092 not be fully avoided as phpMyAdmin is kind of application which needs to
3093 transfer big amounts of columns in single HTTP request, what is something
3094 what Suhosin tries to prevent. Generally all
3095 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3096 <code>suhosin.get.*</code> directives can have negative effect on

3193 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3195 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3196 In your <i>php.ini</i> you will find a line</p>
3198 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3200 <p> change it to</p>
3202 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3204 <p> Then restart apache and it will work.</p>
3206 <p> Here is a fix suggested by Brad Ummer:</p>
3208 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3209 To do this, telnet to your server and go to the MySQL bin directory. In
3210 this directory there should be a file named <i>mysqladmin</i>. Type
3211 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3212 info about your MySQL server, including the socket
3213 (<i>/tmp/mysql.sock</i>, for example).</li>
3214 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3215 phpMyAdmin, you need to complete the socket information in the
3216 <i>config.inc.php</i>.<br />
3217 For example:
3218 <a href="#cfg_Servers_socket" class="configrule">
3219 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
3220 <br /><br />
3222 Please also make sure that the permissions of this file allow to be readable
3223 by your webserver (i.e. '0755').</li>
3224 </ul>
3226 <p> Have also a look at the
3227 <a href="http://dev.mysql.com/doc/en/can-not-connect-to-server.html">

3255 <p> When you are using a port on your localhost, which you redirect via
3256 port-forwarding to another host, MySQL is not resolving the localhost
3257 as expected.<br />
3258 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
3259 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3260 connection for speeding up things. And that doesn't work in this configuration
3261 with port forwarding.<br />

3267 <p> Themes are configured with
3268 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>,
3269 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
3270 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
3271 <br />
3272 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
3273 should not delete the directory &quot;original&quot; or its underlying
3274 structure, because this is the system theme used by phpMyAdmin.
3275 &quot;original&quot; contains all images and styles, for backwards
3276 compatibility and for all themes that would not include images or css-files.
3277 <br /><br />
3279 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
3280 is enabled, you can select your favorite theme on the main page. Your
3281 selected theme will be stored in a cookie.<br /><br /></p>
3283 <p> To create a theme:</p>
3285 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
3286 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
3287 (by default <tt>themes</tt>)</li>
3288 <li>copy the files and directories from &quot;original&quot; to
3289 &quot;your_theme_name&quot;</li>
3290 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
3291 <li>put your new images in &quot;your_theme_name/img&quot;</li>
3292 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
3293 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
3294 contain your chosen theme name, that will be visible in user interface</li>
3295 <li>make a new screenshot of your theme and save it under
3296 &quot;your_theme_name/screen.png&quot;</li>
3297 </ul>
3299 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3300 theme verbose name, theme generation and theme version. These versions and
3301 generations are enumerated from 1 and do not have any direct dependence on
3302 phpMyAdmin version. Themes within same generation should be backwards
3303 compatible - theme with version 2 should work in phpMyAdmin requiring
3304 version 1. Themes with different generation are incompatible.</p>
3306 <p> If you do not want to use your own symbols and buttons, remove the
3307 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
3308 use the default icons and buttons (from the system-theme &quot;original&quot;).

4102 To use SQL Validator, you need PHP with
4103 <abbr title="Extensible Markup Language">XML</abbr>,
4104 <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
4105 <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
4106 In addition you need a <abbr title="Simple Object Access
4107 Protocol">SOAP</abbr> support, either as a PHP extension or as a PEAR SOAP
4108 module.
4109 </p>
4112 To install <abbr title="PHP Extension and Application
4113 Repository">PEAR</abbr> <abbr title="Simple Object Access
4114 Protocol">SOAP</abbr> module, run <tt>"pear install Net_Socket Net_URL

4116 title="PHP Extension and Application Repository">PEAR</abbr> modules for
4117 usage.
4118 </p>
4121 If you use the Validator, you should be aware that any
4122 <abbr title="structured query language">SQL</abbr> statement you
4123 submit will be stored anonymously (database/table/column names,
4124 strings, numbers replaced with generic values). The Mimer
4125 <abbr title="structured query language">SQL</abbr>

4135 <p> The right way to do this, is to create the column without any indexes,
4136 then display the table structure and use the &quot;Create an index&quot;
4137 dialog. On this page, you will be able to choose your BLOB column, and
4138 set a size to the index, which is the condition to create an index on

4146 with many editing fields (table structure changes, row editing, etc.).
4147 You can also have a look at the directive

4152 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
4153 WTF is this feature then useful for?</a></h4>
4155 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4156 on them. Otherwise you could just put a comment on the column. Because entering
4157 your own mimetype will cause serious syntax checking issues and validation,
4158 this introduces a high-risk false-user-input situation. Instead you have to
4159 initialize mimetypes using functions or empty mimetype definitions.<br />
4160 Plus, you have a whole overview of available mimetypes. Who knows all those
4161 mimetypes by heart so he/she can enter it at will?</p>
4163 <h4 id="faqbookmark">
4164 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
4165 can't I see any bookmarks below the query box? What is this variable for?
4166 </a></h4>
4168 <p> Any query you have executed can be stored as a bookmark on the page where the
4169 results are displayed. You will find a button labeled 'Bookmark this query'
4170 just at the end of the page.<br />
4171 As soon as you have stored a bookmark, it is related to the database you run
4172 the query on. You can now access a bookmark dropdown on each page, the query
4173 box appears on for that database.<br /><br />
4175 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4176 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
4177 which is put into the <i>value</i> input box on the query box page will
4178 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
4179 aware of that you HAVE to create a valid query, otherwise your query won't be
4180 even able to be stored in the database.<br />
4181 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
4182 for your query will remain the way it is, but will be stripped of the /**/
4183 chars. So you can use:<br /><br />
4185 <code>/*, [VARIABLE] AS myname */</code><br /><br />
4187 which will be expanded to<br /><br />
4189 <code>, VARIABLE as myname</code><br /><br />
4191 in your query, where VARIABLE is the string you entered in the input box. If
4192 an empty string is provided, no replacements are made.<br /><br />
4194 A more complex example. Say you have stored this query:<br /><br />
4195 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
4196 <br /><br />
4198 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
4199 the full query will be:<br /><br />
4201 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
4202 <br /><br />
4204 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
4205 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
4206 spaces inserted there
4207 will be later also inserted as spaces in your query and may lead to unexpected
4208 results especially when
4209 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
4210 Your initial query which is going to be stored as a bookmark has to yield at
4211 least one result row so
4212 you can store the bookmark. You may have that to work around using well
4213 positioned &quot;/**/&quot; comments.</p>

4250 <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
4251 6.6</a> for an example. Then, if there are 100 values or less in the

4253 You will see two lists of values, the first list containing the key
4254 and the display column, the second list containing the display column
4255 and the key. The reason for this is to be able to type the first
4256 letter of either the key or the display column.<br /><br />
4258 For 100 values or more, a distinct window will appear, to browse foreign
4259 key values and choose one. To change the default limit of 100, see

4296 </ul>
4298 <p>Here are details about configuration and operation:</p>
4300 <ol>
4301 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of &quot;localhost&quot;.</li>
4302 <li>Ensure that your target table is under the <tt>PBXT</tt> storage engine and has a <tt>LONGBLOB</tt> column (which must be nullable if you want to remove the BLOB reference from it).</li>
4303 <li>When you insert or update a row in this table, put a checkmark on the &quot;Upload to BLOB repository&quot; optional choice; otherwise, the upload will be done directly in your LONGBLOB column instead of the repository.</li>
4304 <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example &quot;View image&quot;. A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time.</li>

4346 By clicking on the button 'toggle scratchboard' on the page
4347 where you edit x/y coordinates of those elements you can activate a
4348 scratchboard where all your elements are placed. By clicking on an
4349 element, you can move them around in the pre-defined area and the x/y
4350 coordinates will get updated dynamically. Likewise, when entering a
4351 new position directly into the input field, the new position in the
4352 scratchboard changes after your cursor leaves the input field.
4353 </p>
4355 You have to click on the 'OK'-button below the tables to save the new

4360 By changing the paper size and the orientation you can change the size
4361 of the scratchboard as well. You can do so by just changing the
4362 dropdown field below, and the scratchboard will resize automatically,
4363 without interfering with the current placement of the elements.

4395 translate online at our <a href="http://l10n.cihar.com/">translation
4396 server</a> where you can also get the latest po files and merge them
4397 with your translations. For creating a new translation simply use
4398 <code>po/phpmyadmin.pot</code> and generate
4399 <code>po/LANG_CODE.po</code> for your language (you can use
4400 <code>msginit -i po/phpmyadmin.pot -l LANG_CODE --no-translator -o po/LANG_CODE.po</code>
4401 to do this) or ask on the mailing list to add the translation to the web
4402 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Gettext_for_translators">our wiki</a>.
4403 </p>
4405 Please note that we try not to use HTML entities like &amp;eacute; in
4406 the translations, since we define the right character set in the file.
4407 With HTML entities, the text on JavaScript messages would not
4408 display correctly.
4409 However there are some entities that need to be there: quotes,
4410 non-breakable spaces, ampersands, less than, greater than.
4411 </p>
4413 You can then put your translations, as a zip file to avoid losing special

4512 in sync with another database. Other than the full database, certain
4513 tables of the databases can also be synchronized.
4514 </p>
4517 You need to fill in the host name of the server, the username and
4518 password of an user account already there in MySQL. Port is by default
4519 populated with 3306 (MySQL default port). Then the name of the database
4520 should be mentioned at the end. All the information other than the port
4521 needs to be filled explicitly for the source as well as target servers.
4522 </p>
4525 After successfully passing through the authentication phase, the source and
4526 target database table names will be displayed. It will be a tabular
4527 representation.
4528 </p>
4531 On the left, are listed the source database table names. Some of the
4532 names have a <code>+</code> plus sign preceding them. This shows that these tables
4533 are only present in source database and they need to be added to the
4534 target database in order to synchronize the target database. The tables
4535 whose names are not preceded by a <code>+</code> sign are already present in the
4536 target database.
4537 </p>
4540 On the right, are listed the target database table names. There are few
4541 table names that have <code>(not present)</code> appended after their names. This
4542 means that these tables are to be created in target database in order to
4543 synchronize target database with source database. Some table names
4544 have a <code>-</code> minus sign preceding them. This shows that these tables are
4545 only present in target database and they will remain unchanged in the
4546 target database. The column in the middle shows the difference between
4547 the source and target corresponding tables.
4548 </p>
4551 The difference is depicted by the red and green buttons with <tt>S</tt> and <tt>D</tt>
4552 letters, indicating that either Structure or Data are not up to date. By
4553 clicking on them, they will turn grey, what means that they will be synchronized.
4554 </p>
4556 <!-- DEVELOPERS -->
4557 <h2 id="developers">Developers Information</h2>
4559 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
4560 great features have been written by other people and you too can help to
4561 make phpMyAdmin a useful tool.</p>
4563 <p> If you're planning to contribute source, please read the following
4564 information:</p>
4566 <ul><li>All files include <i>libraries/header.inc.php</i> (layout),.
4567 <i>libraries/common.lib.php</i> (common functions) and
4568 <i>config.inc.php</i>.<br />
4569 Only configuration data should go in <i>config.inc.php</i>. Please keep
4570 it free from other code.<br />
4571 Commonly used functions should be added to
4572 <i>libraries/common.lib.php</i> and more specific ones may be added
4573 within a library stored into the <i>libraries</i> sub-directory.</li>
4574 <li>Obviously, you're free to use whatever coding style you want. But
4575 please try to keep your code as simple as possible: beginners are
4576 using phpMyAdmin as an example application.<br />
4577 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4578 compliant on one hand, they fit the
4579 <a href="http://pear.php.net/">
4580 <abbr title="PHP Extension and Application Repository">PEAR</abbr>
4581 coding standards</a>
4582 on the other hand. Please pay attention to this.</li>
4583 <li>Please enable showing PHP errors and warnings by the
4584 <code><a href="#cfg_Error_Handler_display">$cfg['Error_Handler']['display']</a></code>
4585 configuration directive.</li>
4586 <li>Please try to keep up the file-naming conventions. Table-related stuff
4587 goes to <i>tbl_*.php</i>, db-related code to <i>db_*.php</i>,
4588 server-related tools to <i>server_*.php</i> and so on.</li>
4589 <li>Please use gettext wrappers around all messages
4590 (<code>__('Some text')</code> or <code>_ngettext()</code> function).
4591 To translate them, you need to call <code>scripts/update-po</code>
4592 script. To use translated messages, call
4593 <code>scripts/generate-mo</code>, which generates binary files read by
4594 Gettext.</li>
4595 <li>If you want to be really helpful, write an entry for the ChangeLog.</li>
4596 <li id="developersdbg">
4597 The DBG extension (<a href="http://dd.cron.ru/dbg/">PHP
4598 Debugger DBG</a>) is now supported by phpMyAdmin for developers to
4599 better debug and profile their code.<br />
4600 Please see the
4601 <a href="#cfg_DBG" class="configrule">$cfg['DBG']*</a> configuration
4602 options for more information.<br />
4603 This is in memoriam of the Space Shuttle Columbia (STS-107) which was
4604 lost during its re-entry into Earth's atmosphere and in memory of the
4605 brave men and women who gave their lives for the people of Earth.</li>

4932 <h3>Original Credits of Version 2.1.0</h3>
4935 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4936 to create a web-based interface to MySQL using PHP3. Although I have not
4937 used any of his source-code, there are some concepts I've borrowed from
4938 him. phpMyAdmin was created because Peter told me he wasn't going to
4939 further develop his (great) tool.
4940 </p>
4942 Thanks go to
4943 </p>
4944 <ul>
4945 <li>Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4946 code for the check when dropping a table or database. He also suggested
4947 that you should be able to specify the primary key on tbl_create.php3. To
4948 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4949 well as a bug-report. Plus many smaller improvements.
4950 </li>
4951 <li>Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4952 were introduced in 1.3.0 (including quite significant ones like the
4953 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4954 bug-fixes and help.
4955 </li>
4956 <li>Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4957 language-independent by outsourcing the strings to a separate file. He
4958 also contributed the French translation.
4959 </li>
4960 <li>Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4961 tbl_select.php3, a feature to display only some columns from a table.
4962 </li>
4963 <li>Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4964 functions in tbl_change.php3. He also added the
4965 &quot;Query by Example&quot; feature in 2.0.
4966 </li>
4967 <li>Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4968 servers and is a regular contributor for bug-fixes.
4969 </li>
4970 <li>Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4971 features for 2.0.6.
4972 </li>
4973 </ul>
4975 The following people have contributed minor changes, enhancements, bugfixes
4976 or support for a new language:
