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

132 <h4>A word about users:</h4>
133 <p> Many people have difficulty
134 understanding the concept of user management with regards to phpMyAdmin. When
135 a user logs in to phpMyAdmin, that username and password are passed directly
136 to MySQL. phpMyAdmin does no account management on its own (other than
137 allowing one to manipulate the MySQL user account information); all users
138 must be valid MySQL users.</p>
140 <p class="footnote" id="footnote_1">
141 <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
142 dumps and <abbr title="comma seperated values">CSV</abbr> exports if you use
143 PHP with Zlib support (<tt>--with-zlib</tt>) and/or Bzip2 support
144 (<tt>--with-bz2</tt>). Proper support may also need changes in
145 <tt>php.ini</tt>.</p>

155 </ol>
157 <p class="important">
158 phpMyAdmin does not apply any special security methods to the MySQL database
159 server. It is still the system administrator's job to grant permissions on
160 the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
161 be used for this.
162 </p>
164 <p class="important">
165 Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
166 if you are on a <acronym title="Apple Macintosh">Mac</acronym>
167 <abbr title="operating system">OS</abbr> version before
168 <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
169 <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
170 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
171 before uploading them to your server, as PHP seems not to like
172 <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
173 (&quot;<tt>\r</tt>&quot;).</p>
175 <h3 id="quick_install">Quick Install</h3>
176 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
177 Downloads page. Some kits contain only the English messages,
178 others contain all languages in UTF-8 format (this should be fine
179 in most situations), others contain all
180 languages and all character sets. We'll assume you chose a kit whose
181 name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
182 </li>
183 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
184 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
185 document root. If you don't have direct access to your document root,
186 put the files in a directory on your local machine, and, after step 4,
187 transfer the directory on your web server using, for example, ftp.</li>
188 <li>Ensure that all the scripts have the appropriate owner (if PHP is
189 running in safe mode, having some scripts with an owner different
190 from the owner of other scripts will be a
191 problem). See <a href="#faq4_2">
192 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
193 <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
194 1.26</a> for suggestions.</li>
195 <li>Now you must configure your installation. There are two methods that
196 can be used. Traditionally, users have hand-edited a copy of
197 <tt>config.inc.php</tt>, but now a wizard-style setup script is
198 provided for those who prefer a graphical installation. Creating a
199 <tt>config.inc.php</tt> file is
200 still a quick way to get started and needed for some advanced features.
201 <ul><li>To manually create the file, simply use your text editor to
202 create the file <tt>config.inc.php</tt> (you can copy
203 <tt>config.sample.inc.php</tt> to get minimal configuration
204 file) in the main (top-level) phpMyAdmin directory (the one
205 that contains <tt>index.php</tt>). phpMyAdmin first loads
206 <tt>libraries/config.default.php</tt> and then overrides those
207 values with anything found in <tt>config.inc.php</tt>. If the
208 default value is okay for a particular setting, there is no
209 need to include it in <tt>config.inc.php</tt>. You'll need a
210 few directives to get going, a simple configuration may look
211 like this:
212 <pre>
213 &lt;?php
214 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
216 $i=0;
217 $i++;
218 $cfg['Servers'][$i]['auth_type'] = 'cookie';
219 ?&gt;
220 </pre>
221 Or, if you prefer to not be prompted every time you log in:
222 <pre>
223 &lt;?php
225 $i=0;
226 $i++;
227 $cfg['Servers'][$i]['user'] = 'root';
228 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
229 ?&gt;
230 </pre>
231 For a full explanation of possible configuration values, see the
232 <a href="#config">Configuration Section</a> of this document.</li>
233 <li id="setup_script">Instead of manually editing
234 <tt>config.inc.php</tt>, you can use the
235 <a href="scripts/setup.php">Setup Script</a>. First you must
236 manually create a folder <tt>config</tt> in the phpMyAdmin
237 directory. This is a security measure. On a Linux/Unix system you
238 can use the following commands:
239 <pre>
240 cd phpMyAdmin
241 mkdir config # create directory for saving
242 chmod o+rw config # give it world writable permissions
243 </pre>
244 And to edit an existing configuration, copy it over first:
245 <pre>
246 cp config.inc.php config/ # copy current configuration for editing
247 chmod o+w config/config.inc.php # give it world writable permissions
248 </pre>
249 On other platforms, simply create the folder and ensure that your
250 web server has read and write access to it. <a href="#faq1_26">FAQ
251 1.26</a> can help with this.<br /><br />
253 Next, open <tt><a href="scripts/setup.php">scripts/setup.php</a>
254 </tt>in your browser. Note that <strong>changes are not saved to
255 disk until explicitly choose <tt>Save</tt></strong> from the
256 <i>Configuration</i> area of the screen. Normally the script saves
257 the new config.inc.php to the <tt>config/</tt> directory, but if
258 the webserver does not have the proper permissions you may see the
259 error "Cannot load or save configuration." Ensure that the <tt>
260 config/</tt> directory exists and has the proper permissions -
261 or use the <tt>Download</tt> link to save the config file locally
262 and upload (via FTP or some similar means) to the proper location.<br /><br />
264 Once the file has been saved, it must be moved out of the <tt>
265 config/</tt> directory and the permissions must be reset, again
266 as a security measure:
267 <pre>
268 mv config/config.inc.php . # move file to current directory
269 chmod o-rw config.inc.php # remove world read and write permissions
270 </pre>
271 Now the file is ready to be used. You can choose to review or edit
272 the file with your favorite editor, if you prefer to set some
273 advanced options which the setup script does not provide.</li></ul></li>
274 <li>If you are using the
275 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
276 protect the phpMyAdmin installation directory because using
277 config does not require a user to
278 enter a password to access the phpMyAdmin installation. Use of an alternate
279 authentication method is recommended, for example with
280 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
281 <tt>auth_type</tt> cookie or http. See the
282 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
283 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
284 information, especially <a href="#faq4_4">
285 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
286 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
287 in your browser. phpMyAdmin should now display a welcome screen
288 and your databases, or a login dialog if using
289 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
290 authentication mode.</li>
291 <li>You should deny access to the <tt>./libraries</tt> subfolder in your
292 webserver configuration. For Apache you can use supplied .htaccess file
293 in that folder, for other webservers, you should configure this yourself.
294 Such configuration prevents from possible path exposure and cross side
295 scripting vulnerabilities that might happen to be found in that code.</li>
296 </ol>
298 <h3 id="linked-tables">Linked-tables infrastructure</h3>
300 <p> For a whole set of new features (bookmarks, comments,
301 <abbr title="structured query language">SQL</abbr>-history,
302 <abbr title="Portable Document Format">PDF</abbr>-generation, field contents
303 transformation, etc.) you need to create a set of special tables. Those
304 tables can be located in your own database, or in a central database for a
305 multi-user installation (this database would then be accessed by the
306 controluser, so no other user should have rights to it).</p>
308 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
309 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
310 special attention to <a href="#faq1_23">
311 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
313 <p> If your MySQL server's version is 4.1.2 or later, please use
314 <i>./scripts/create_tables_mysql_4_1_2+.sql</i> instead, for a new
315 installation.</p>
317 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
318 or later, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>.</p>
320 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
321 that you may need special (administrator) privileges to create the database
322 and tables, and that the script may need some tuning, depending on the
323 database name.</p>
325 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
326 should specify the table names in your <i>./config.inc.php</i> file. The
327 directives used for that can be found in the <a href="#config">Configuration
328 section</a>. You will also need to have a controluser with the proper rights
329 to those tables (see section <a href="#authentication_modes">Using
330 authentication modes</a> below).</p>
332 <h3 id="upgrading">Upgrading from an older version</h3>
334 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
335 unpacked one. Configuration files from very old versions (2.3.0 or before) may
336 require some tweaking as some options have been changed or removed.
337 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
338 statement that you might find near the end of your configuration file.</p>
340 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
341 over <tt>config.inc.php</tt> because the default configuration file
342 is version-specific.</p>
344 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
345 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
346 you should run the SQL script found in
347 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
349 <h3 id="authentication_modes">Using authentication modes</h3>
351 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
352 authentication modes are recommended in a <b>multi-user environment</b>
353 where you want to give users access to their own database and don't want
354 them to play around with others.<br />
355 Nevertheless be aware that MS Internet Explorer seems to be really buggy
356 about cookies, at least till version 6, and PHP 4.1.1 is also a bit buggy
357 in this area!<br />
358 Even in a <b>single-user environment</b>, you might prefer to use
359 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
360 that your user/password pair are not in clear in the configuration file.
361 </li>
363 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
364 authentication modes are more secure: the MySQL login information does
365 not need to be set in the phpMyAdmin configuration file (except possibly
366 for the <a href="#controluser">controluser</a>).<br />
367 However, keep in mind that the password travels in plain text, unless
368 you are using the HTTPS protocol.<br />
369 In cookie mode, the password is stored, encrypted with the blowfish
370 algorithm, in a temporary cookie.</li>
372 <li>Note: starting with phpMyAdmin 2.6.1, this section is only applicable if
373 your MySQL server is previous to 4.1.2, or is running with
374 <tt>--skip-show-database</tt>.<br /><br />
376 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
377 modes, phpMyAdmin needs a controluser that has <b>only</b> the
378 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
379 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
380 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
381 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
382 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
383 file under the
384 <tt><a href="#cfg_Servers_controluser" class="configrule">
385 $cfg['Servers'][$i]['controluser']</a></tt> and
386 <tt><a href="#cfg_Servers_controlpass" class="configrule">
387 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
388 The following example assumes you want to use <tt>pma</tt> as the
389 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
390 only an example: use something else in your file!</b> Input these
391 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
392 client.<br />
393 Of course you have to replace <tt>localhost</tt> with the webserver's host
394 if it's not the same as the MySQL server's one.
396 <pre>
397 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
398 GRANT SELECT (
399 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
400 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
401 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
402 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
403 Execute_priv, Repl_slave_priv, Repl_client_priv
404 ) ON mysql.user TO 'pma'@'localhost';
405 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
406 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
407 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
408 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
410 If you are using an old MySQL version (below 4.0.2), please replace
411 the first GRANT SELECT query by this one:
413 <pre>
414 GRANT SELECT (
415 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
416 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
417 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv
418 ) ON mysql.user TO 'pma'@'localhost';</pre>
420 ... and if you want to use the many new relation and bookmark features:
422 <pre>
423 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
424 </pre>
426 (this of course requires that your <a href="#linked-tables">linked-tables
427 infrastructure</a> be set up).<br />
428 Of course, the above queries only work if your MySQL version supports
429 the GRANT command. This is the case since 3.22.11.</li>
431 <li>Then each of the <i>true</i> users should be granted a set of privileges
432 on a set of particular databases. Normally you shouldn't give global
433 privileges to an ordinary user, unless you understand the impact of those
434 privileges (for example, you are creating a superuser).<br />
435 For example, to grant the user <i>real_user</i> with all privileges on
436 the database <i>user_base</i>:<br />
438 <pre>
439 GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
440 </pre>
442 What the user may now do is controlled entirely by the MySQL user
443 management system.<br />
444 With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
445 authentication mode, you don't need to fill the user/password fields
446 inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
447 array.</li>
448 </ul>
450 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>

465 using the <i>.htaccess</i> mechanism along with
466 '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication
467 mode.</li>
468 </ul>
470 <h4>'cookie' authentication mode</h4>
472 <ul><li>You can use this method as a replacement for the
473 <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
474 (for example, if you're running
475 <abbr title="Internet Information Services">IIS</abbr>).</li>
476 <li>Obviously, the user must enable cookies in the browser, but this is
477 now a requirement for all authentication modes.</li>
478 <li>With this mode, the user can truly log out of phpMyAdmin and log in back
479 with the same username.</li>
480 <li>If you want to log in to arbitrary server see
481 <a href="#AllowArbitraryServer" class="configrule">
482 $cfg['AllowArbitraryServer']</a> directive.</li>
483 <li>As mentioned in the <a href="#require">requirements</a> section, having
484 the <tt>mcrypt</tt> extension will speed up access considerably, but is
485 not required.</li>
486 </ul>
488 <h4>'signon' authentication mode</h4>
490 <ul><li>This mode is a convenient way of using credentials from another
491 application to authenticate to phpMyAdmin.</li>
492 <li>The other application has to store login information into
493 session data.</li>
494 <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
495 section.</li>
496 </ul>
497 <h4>'config' authentication mode</h4>
499 <ul><li>This mode is the less secure one because it requires you to fill the
500 <a href="#servers_user" class="configrule">
501 $cfg['Servers'][$i]['user']</a> and
502 <a href="#servers_user" class="configrule">
503 $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
504 can read your config.inc.php can discover your username and password).
505 <br />
506 But you don't need to setup a &quot;controluser&quot; here: using the
507 <a href="#servers_only_db" class="configrule">
508 $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
509 <li>In the <a href="#faqmultiuser">
510 <abbr title="Internet service provider">ISP</abbr>
511 <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
512 is an entry explaining how to protect your configuration file.</li>
513 <li>For additional security in this mode, you may wish to consider the Host
514 authentication
515 <a href="#servers_allowdeny_order" class="configrule">
516 $cfg['Servers'][$i]['AllowDeny']['order']</a> and
517 <a href="#servers_allowdeny_rules" class="configrule">
518 $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
519 directives.</li>
520 <li>Unlike cookie and http, does not require a user to log in when first
521 loading the phpMyAdmin site. This is by design but could allow any
522 user to access your installation. Use of some restriction method is
523 suggested, perhaps a <a href="#glossary">.htaccess</a> file with the
524 HTTP-AUTH directive or disallowing incoming HTTP requests at
525 one&#8217;s router or firewall will suffice (both of which
526 are beyond the scope of this manual but easily searchable with Google).</li>

557 Don&#8217;t forget the trailing slash at the end.<br /><br />
559 Starting with version 2.3.0, it is advisable to try leaving this

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

694 <li>'cookie' authentication mode
695 (<tt>$auth_type&nbsp;=&nbsp;'cookie'</tt>) as introduced in
696 2.2.3 allows you to log in as any valid MySQL user with the
697 help of cookies. Username and password are stored in
698 cookies during the session and password is deleted when it
699 ends. This can also allow you to log in in arbitrary server if

705 <li>'signon' authentication mode
706 (<tt>$auth_type&nbsp;=&nbsp;'signon'</tt>)
707 as introduced in 2.10.0 allows you to log in from prepared PHP
708 session data. This is useful for implementing single signon
709 from another application. Sample way how to seed session is in
710 signon example: <code>scripts/signon.php</code>. You need to

744 If set to a (an array of) database name(s), only this (these) database(s)
745 will be shown to the user. Since phpMyAdmin 2.2.1, this/these
746 database(s) name(s) may contain MySQL wildcards characters
747 (&quot;_&quot; and &quot;%&quot;): if you want to use literal instances
748 of these characters, escape them (I.E. use <tt>'my\_db'</tt> and not
749 <tt>'my_db'</tt>).<br />
750 This setting is an efficient way to lower the server load since the
751 latter does not need to send MySQL requests to build the available
752 database list. But <span class="important">it does not replace the
753 privileges rules of the MySQL database server</span>. If set, it just
754 means only these databases will be displayed but
755 <span class="important">not that all other databases can't be used.</span>

758 An example of using more that one database:
759 <tt>$cfg['Servers'][$i]['only_db'] = array('db1', 'db2');</tt>
760 <br /><br />
762 As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the
763 databases in the left frame, so that you can individually arrange your databases.<br />
764 If you want to have certain databases at the top, but don't care about the others, you do not
765 need to specify all other databases. Use:
766 <tt>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</tt>
767 instead to tell phpMyAdmin that it should display db3 and db4 on top, and the rest in alphabetic

772 <dd>Regular expression for hiding some databases. This only hides them
773 from listing, but a user is still able to access them (using, for example,
774 the SQL query area). To limit access, use the MySQL privilege system.
775 <br /><br />
776 For example, to hide all databases starting with the letter &#34;a&#34;, use<br />
777 <pre>$cfg['Servers'][$i]['hide_db'] = '^a';</pre>
778 and to hide both &#34;db1&#34; and &#34;db2&#34; use <br />

916 <dd><!-- This part requires a content update! -->
917 Since release 2.3.0 you can store comments to describe each column for
918 each table. These will then be shown on the &quot;printview&quot;.
919 <br /><br />
921 Starting with release 2.5.0, comments are consequently used on the table
922 property pages and table browse view, showing up as tool-tips above the
923 column name (properties page) or embedded within the header of table in
924 browse view. They can also be shown in a table dump. Please see the
925 relevant configuration directives later on.<br /><br />
927 Also new in release 2.5.0 is a MIME-transformation system which is also
928 based on the following table structure. See <a href="#transformations">
929 Transformations</a> for further information. To use the
930 MIME-transformation system, your column_info table has to have the three
931 new fields 'mimetype', 'transformation', 'transformation_options'.
932 <br /><br />
934 To allow the usage of this functionality:
935 <ul><li>set up <a href="#pmadb">pmadb</a> and the linked-tables
936 infrastructure</li>
937 <li>put the table name in
938 <tt>$cfg['Servers'][$i]['column_info']</tt></li>
939 <li>to update your PRE-2.5.0 Column_comments Table use this:
941 <pre>
942 ALTER TABLE `pma_column_comments`
943 ADD `mimetype` VARCHAR( 255 ) NOT NULL,
944 ADD `transformation` VARCHAR( 255 ) NOT NULL,
945 ADD `transformation_options` VARCHAR( 255 ) NOT NULL;
946 </pre>
948 and remember that the Variable in <i>config.inc.php</i> has been
949 renamed from<br />
950 <tt>$cfg['Servers'][$i]['column_comments']</tt> to
951 <tt>$cfg['Servers'][$i]['column_info']</tt></li>

958 <dd>Since release 2.5.0 you can store your
959 <abbr title="structured query language">SQL</abbr> history, which means
960 all queries you entered manually into the phpMyAdmin interface. If you
961 don't want to use a table-based history, you can use the JavaScript-based
962 history. Using that, all your history items are deleted when closing the
963 window.<br /><br />
965 Using
966 <a href="#cfg_QueryHistoryMax" class="configrule">$cfg['QueryHistoryMax']</a>
967 you can specify an amount of history items you want to have on hold. On
968 every login, this list gets cut to the maximum amount.<br /><br />
970 The query history is only available if JavaScript is enabled in your
971 browser.<br /><br />
973 To allow the usage of this functionality:
975 <ul><li>set up <a href="#pmadb">pmadb</a> and the linked-tables

1002 is set to <tt>TRUE</tt> (default) phpMyAdmin will check if you have the
1003 latest table structure available. If not, it will emit a warning to the
1004 superuser.<br /><br />
1006 You can disable this checking behavior by setting the variable to false,
1007 which should offer a performance increase.<br /><br />
1009 Recommended to set to FALSE, when you are sure, your table structure is
1010 up to date.</dd>

1018 <dd>If your rule order is empty, then <abbr title="Internet Protocol">IP</abbr>
1019 authentication is disabled.<br /><br />
1021 If your rule order is set to <tt>'deny,allow'</tt> then the system applies
1022 all deny rules followed by allow rules. Access is allowed by default. Any
1023 client which does not match a Deny command or does match an Allow command
1024 will be allowed access to the server. <br /><br />
1026 If your rule order is set to <tt>'allow,deny'</tt> then the system
1027 applies all allow rules followed by deny rules. Access is denied by
1028 default. Any client which does not match an Allow directive or does
1029 match a Deny directive will be denied access to the server.<br /><br />
1031 If your rule order is set to 'explicit', the authentication is
1032 performed in a similar fashion to rule order 'deny,allow', with the
1033 added restriction that your host/username combination <b>must</b> be
1034 listed in the <i>allow</i> rules, and not listed in the <i>deny</i>
1035 rules. This is the <b>most</b> secure means of using Allow/Deny rules,
1036 and was available in Apache by specifying allow and deny rules without
1037 setting any order.<br /><br />

1050 </pre>
1052 If you wish to match all users, it is possible to use a <tt>'%'</tt> as
1053 a wildcard in the <i>username</i> field.<br />
1054 There are a few shortcuts you can use in the <i>ipmask</i> field as
1055 well (please note that those containing SERVER_ADDRESS might not be

1061 'localnetB' -&gt; SERVER_ADDRESS/16
1062 'localnetC' -&gt; SERVER_ADDRESS/24
1063 </pre>
1065 Having an empty rule list is equivalent to either using
1066 <tt>'allow % from all'</tt> if your rule order is set to
1067 <tt>'deny,allow'</tt> or <tt>'deny % from all'</tt> if your rule order

1774 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
1775 or icon is always displayed on the left panel. If JavaScript is enabled in
1776 your browser, a click on this opens a distinct query window, which is
1777 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
1778 changes to display a query box.<br /><br />
1780 The size of this query window can be customized with
1781 <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowWidth']</tt>
1782 - both integers for the size in pixels. Note that normally, those
1783 parameters will be modified in <tt>layout.inc.php</tt> for the
1784 theme you are using.<br /><br />
1786 If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
1787 from the results page (in the &quot;Showing Rows&quot; section)
1788 opens the query window and puts the current query
1789 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
1790 query in the right panel's query box.
1791 <br /><br />
1792 The usage of the JavaScript query window is recommended if you have a
1793 JavaScript enabled browser. Basic functions are used to exchange quite
1794 a few variables, so most 4th generation browsers should be capable to
1795 use that feature. It currently is only tested with Internet Explorer 6

1798 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
1799 to a table, which has to be created by you (see <a
1800 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
1801 all your queries will be appended to the form, but only as long as
1802 your window is opened they remain saved.
1803 <br /><br />
1804 When using the JavaScript based query window, it will always get
1805 updated when you click on a new table/db to browse and will focus if
1806 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
1807 the query window by checking the box "Do not overwrite this query from
1808 outside the window" below the query textarea. Then you can browse
1809 tables/databases in the background without losing the contents of the
1810 textarea, so this is especially useful when composing a query with
1811 tables you first have to look in. The checkbox will get automatically
1812 checked whenever you change the contents of the textarea. Please
1813 uncheck the button whenever you definitely want the query window to
1814 get updated even though you have made alterations.
1815 <br /><br />
1816 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
1817 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
1818 <br /><br />
1819 The query window also has a custom tabbed look to group the features.
1820 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
1821 default tab to be used when opening the query window. It can be set to
1822 either 'sql', 'files', 'history' or 'full'.</dd>

1846 page. By clicking on the button 'toggle scratchboard' on the page
1847 where you edit x/y coordinates of those elements you can activate a
1848 scratchboard where all your elements are placed. By clicking on an
1849 element, you can move them around in the pre-defined area and the x/y
1850 coordinates will get updated dynamically. Likewise, when entering a
1851 new position directly into the input field, the new position in the
1852 scratchboard changes after your cursor leaves the input field.<br />
1853 You have to click on the 'OK'-button below the tables to save the new
1854 positions. If you want to place a new element, first add it to the
1855 table of elements and then you can drag the new element around.<br />
1856 By changing the paper size and the orientation you can change the size
1857 of the scratchboard as well. You can do so by just changing the
1858 dropdown field below, and the scratchboard will resize automatically,
1859 without interfering with the current placement of the elements.<br />
1860 If ever an element gets out of range you can either enlarge the paper
1861 size or click on the 'reset' button to place all elements below each
1862 other.<br />

2075 <h2 id="transformations">Transformations</h2>
2077 <ol><li><a href="#transformationsintro">Introduction</a></li>
2078 <li><a href="#transformationshowto">Usage</a></li>
2079 <li><a href="#transformationsfiles">File structure</a></li>
2080 </ol>
2082 <h3 id="transformationsintro">1. Introduction</h3>
2084 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2085 and the proper directives. Please see the <a href="#config">Configuration
2086 section</a> on how to do so.</p>
2088 <p> You can apply different transformations to the contents of each field. The
2089 transformation will take the content of each field and transform it with
2090 certain rules defined in the selected transformation.</p>
2092 <p> Say you have a field 'filename' which contains a filename. Normally you would
2093 see in phpMyAdmin only this filename. Using transformations you can transform
2094 that filename into a HTML link, so you can click inside of the phpMyAdmin
2095 structure on the field's link and will see the file displayed in a new browser
2096 window. Using transformation options you can also specify strings to
2097 append/prepend to a string or the format you want the output stored in.</p>
2099 <p> For a general overview of all available transformations and their options,
2100 you can consult your
2101 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2102 installation.</p>
2104 <p> For a tutorial on how to effectively use transformations, see our
2105 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2106 the official phpMyAdmin homepage.</p>
2108 <h3 id="transformationshowto">2. Usage</h3>
2110 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2111 clicking on the 'Structure' link for a table). There click on
2112 &quot;Change&quot; (or change icon) and there you will see three new fields at
2113 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2114 'Transformation options'.</p>
2116 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2117 that corresponds to the column's contents. Please note that
2118 transformations are inactive as long as no MIME-type is selected.</li>
2120 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2121 hopefully growing amount of pre-defined transformations. See below for information on
2122 how to build your own transformation.<br />
2124 There are global transformations and mimetype-bound transformations. Global transformations
2125 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2126 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2127 transformations which operate on the main mimetype (like 'image'), which will most likely
2128 take the subtype into regard, and those who only operate on a
2129 specific subtype (like 'image/jpeg').<br />
2131 You can use transformations on mimetypes for which the function was not defined for. There
2132 is no security check for you selected the right transformation, so take care of what the
2133 output will be like.</li>
2135 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2136 transform-function specific options here. Usually the transforms can operate with default
2137 options, but it is generally a good idea to look up the overview to see which options are
2138 necessary.<br />
2140 Much like the ENUM/SET-Fields, you have to split up several options using the format
2141 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2142 parsed as an array, leaving the first value the first element in the array, and so
2143 forth.<br />
2145 If you want to specify a MIME character set you can define it in the transformation_options.
2146 You have to put that outside of the pre-defined options of the specific mime-transform,
2147 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2148 for which you can specify 2 options and you want to append a character set, enter "'first
2149 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2150 the parameters: "'','','charset=us-ascii'".</li>
2151 </ul>
2153 <h3 id="transformationsfiles">3. File structure</h3>
2155 <p> All mimetypes and their transformations are defined through single files in
2156 the directory 'libraries/transformations/'.</p>
2158 <p> They are stored in files to ease up customization and easy adding of new
2159 transformations.</p>
2161 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2162 always work. It makes no sense to apply a transformation to a mimetype, the
2163 transform-function doesn't know to handle.</p>
2165 <p> One can, however, use empty mime-types and global transformations which should work
2166 for many mimetypes. You can also use transforms on a different mimetype they where built
2167 for, but pay attention to option usage as well as what the transformation does to your
2168 field.</p>
2170 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2171 any other transform function and provides some basic functions.</p>
2173 <p> There are 5 possible file names:</p>
2175 <ol><li>A mimetype+subtype transform:<br /><br />
2177 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2179 Please not that mimetype and subtype are separated via '_', which shall
2180 not be contained in their names. The transform function/filename may
2181 contain only characters which cause no problems in the file system as
2182 well as the PHP function naming convention.<br /><br />
2184 The transform function will the be called
2185 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2187 <b>Example:</b><br /><br />
2189 <tt>text_html__formatted.inc.php</tt><br />
2190 <tt>PMA_transform_text_html__formatted()</tt></li>
2192 <li>A mimetype (w/o subtype) transform:<br /><br />
2194 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2196 Please note that there are no single '_' characters.
2197 The transform function/filename may contain only characters which cause
2198 no problems in the file system as well as the PHP function naming
2199 convention.<br /><br />
2201 The transform function will the be called
2202 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2204 <b>Example:</b><br /><br />
2206 <tt>text__formatted.inc.php</tt><br />
2207 <tt>PMA_transform_text__formatted()</tt></li>
2209 <li>A mimetype+subtype without specific transform function<br /><br />
2211 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2213 Please note that there are no '__' characters in the filename. Do not
2214 use special characters in the filename causing problems with the file
2215 system.<br /><br />
2217 No transformation function is defined in the file itself.<br /><br />
2219 <b>Example:</b><br /><br />
2221 <tt>text_plain.inc.php</tt><br />
2222 (No function)</li>
2224 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2226 <tt>[mimetype].inc.php</tt><br /><br />
2228 Please note that there are no '_' characters in the filename. Do not use
2229 special characters in the filename causing problems with the file system.
2230 <br /><br />
2232 No transformation function is defined in the file itself.<br /><br />
2234 <b>Example:</b><br /><br />
2236 <tt>text.inc.php</tt><br />
2237 (No function)</li>
2239 <li>A global transform function with no specific mimetype<br /><br />
2241 <tt>global__[transform].inc.php</tt><br /><br />
2243 The transform function will the be called
2244 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2246 <b>Example:</b><br /><br />
2248 <tt>global__formatted</tt><br />
2249 <tt>PMA_transform_global__formatted()</tt></li>
2250 </ol>
2252 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2253 transform function.</p>
2255 <p> All filenames containing no '__' in themselves are not shown as valid transform

2258 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2259 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2260 without a transform function. Also note the introduction of a function description in

2262 has to exist.</p>
2264 <p> You can use the template generator to generate new functions and entries in the
2265 language file.</p>
2267 <p> To create a new transform function please see

2269 To create a new, empty mimetype please see
2270 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2272 <p> A transform function always gets passed three variables:</p>
2274 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2275 you want to transform.</li>
2276 <li><b>$options</b> - Contains any user-passed options to a transform function
2277 as an array.</li>
2278 <li><b>$meta</b> - Contains an object with field information to your column.
2279 The data is drawn from the output of the
2280 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2281 function. This means, all object properties described on the
2282 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2283 available in this variable and can be used to transform a field accordingly
2284 to unsigned/zerofill/not_null/... properties.<br />
2285 The $meta-&gt;mimetype variable contains the original MIME-type of the
2286 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>

2395 defined in <i>php.ini</i> by the variable <tt>upload_tmp_dir</tt> (usually
2396 the system default is <i>/tmp</i>).<br />
2397 We recommend the following setup for Apache servers running in safe mode,

2401 <li>give ownership to the Apache server's user.group:

2415 So the problem is that this package has a serious bug that was corrected

2443 <p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir
2444 restrictions. Assuming that the restriction allows you to open files in the
2445 current directory ('.'), all you have to do is create a 'tmp' directory
2446 under the phpMyAdmin install directory, with permissions 777 and the same
2447 owner as the owner of your phpMyAdmin directory. The uploaded files will
2448 be moved there, and after execution of your

2483 <a href="#faq1_16">1.16 I cannot upload big dump files (memory,
2484 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or timeout problems).</a>
2485 </h4>
2487 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
2488 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2489 to take advantage of the new import features.</p>
2491 <p> The first things to check (or ask your host provider to check) are the
2492 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2493 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2494 All of these three settings limit the maximum size of data that can be
2495 submitted and handled by PHP. One user also said that post_max_size
2496 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2498 There exist several workarounds if your upload is too big or your
2499 hosting provider is unwilling to change the settings:</p>
2501 <ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
2502 feature. This allows one to
2503 upload a file to the server via scp, ftp, or your favorite file transfer
2504 method. PhpMyAdmin is then able to import the files from the temporary
2505 directory. More information is available in the <a href="#config">Configuration
2506 section</a> of this document.</li>
2507 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
2508 BigDump</a>) to split the files before uploading. We cannot support this
2509 or any third party applications, but are aware of users having success
2510 with it.</li>
2511 <li>If you have shell (command line) access, use MySQL to import the files
2512 directly. You can do this by issuing the &quot;source&quot; command from
2513 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2514 </ul>
2516 <h4 id="faq1_17">
2517 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2518 support?</a></h4>
2520 <p> All MySQL versions from 3.23.32 till 5.0 (except for 4.1.0 and 4.1.1) are
2521 fully supported. Please note that the older your MySQL version is, the more
2522 limitations you will have to face.<br />
2523 phpMyAdmin may connect to your MySQL server using php's classic
2524 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2525 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2526 is available in php 5.0.<br />
2527 Either way, the developers of both extensions recommend to use the classic
2528 extension for MySQL 4.0 and below and MySQLi for MySQL 4.1 and newer.<br />
2529 When compiling php, we strongly recommend that you manually link the MySQL
2530 extension of your choice to a MySQL client library of at least the same
2531 minor version since the one that is bundled with some php distributions is
2532 rather old and might cause problems <a href="#faq1_17a">
2533 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.
2534 If your webserver is running on a windows system, you might want to try
2535 MySQL's
2536 <a href="http://dev.mysql.com/downloads/connector/php/">Connector/PHP</a>
2537 instead of the MySQL / MySQLi extensions that are bundled with the official
2538 php Win32 builds.

2544 message, &quot;Client does not support authentication protocol requested
2545 by server; consider upgrading MySQL client&quot;</a></h5>
2547 <p> You tried to access MySQL with an old MySQL client library. The version of
2548 your MySQL client library can be checked in your phpinfo() output.
2549 In general, it should have at least the same minor version as your server
2550 - as mentioned in <a href="#faq1_17">
2551 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2553 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2554 changed the authentication hash and your PHP is trying to use the old method.
2555 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2556 with the proper client library to match your MySQL installation. Your
2557 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.

2586 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2587 &quot;MySQL extension&quot;. This extension may be part of the PHP
2588 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2589 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2590 to load the extension but failed.<br /><br />

2685 interpreting .php files.</p>
2687 <p> The problems occur when two different (and conflicting) set of directives
2688 are used:</p>
2690 <pre>
2691 SetOutputFilter PHP

2700 <tt>/etc/httpd/conf/httpd.conf</tt>, while
2701 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2702 The recommended way is with <tt>AddType</tt>, so just comment out
2703 the first set of lines and restart Apache:</p>

2841 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
2843 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
2844 In your <i>php.ini</i> you will find a line</p>
2846 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
2848 <p> change it to</p>
2850 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
2852 <p> Then restart apache and it will work.</p>
2854 <p> Here is a fix suggested by Brad Ummer:</p>
2856 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
2857 To do this, telnet to your server and go to the MySQL bin directory. In
2858 this directory there should be a file named <i>mysqladmin</i>. Type
2859 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
2860 info about your MySQL server, including the socket
2861 (<i>/tmp/mysql.sock</i>, for example).</li>
2862 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
2863 phpMyAdmin, you need to complete the socket information in the
2864 <i>config.inc.php</i>.<br />
2865 For example:
2866 <a href="#cfg_Servers_socket" class="configrule">
2867 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
2868 <br /><br />
2870 Please also make sure that the permissions of this file allow to be readable
2871 by your webserver (i.e. '0755').</li>
2872 </ul>
2874 <p> Have also a look at the
2875 <a href="http://www.mysql.com/doc/C/a/Can_not_connect_to_server.html">
2876 corresponding section of the MySQL documentation</a>.</p>

2903 <p> When you are using a port on your localhost, which you redirect via
2904 port-forwarding to another host, MySQL is not resolving the localhost
2905 as expected.<br />
2906 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
2907 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
2908 connection for speeding up things. And that doesn't work in this configuration
2909 with port forwarding.<br />

2917 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
2918 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
2919 <br />
2920 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
2921 should not delete the directory &quot;original&quot; or its underlying
2922 structure, because this is the system theme used by phpMyAdmin.
2923 &quot;original&quot; contains all images and styles, for backwards
2924 compatibility and for all themes that would not include images or css-files.
2925 <br /><br />
2927 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
2928 is enabled, you can select your favorite theme on the main page. Your
2929 selected theme will be stored in a cookie.<br /><br /></p>
2931 <p> To create a theme:</p>
2933 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
2934 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
2935 (by default <tt>themes</tt>)</li>
2936 <li>copy the files and directories from &quot;original&quot; to
2937 &quot;your_theme_name&quot;</li>
2938 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
2939 <li>put your new images in &quot;your_theme_name/img&quot;</li>
2940 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
2941 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
2942 contain your chosen theme name, that will be visible in user interface</li>
2943 <li>make a new screenshot of your theme and save it under
2944 &quot;your_theme_name/screen.png&quot;</li>
2945 </ul>
2947 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
2948 theme verbose name, theme generation and theme version. These versions and
2949 generations are enumerated from 1 and do not have any direct dependence on
2950 phpMyAdmin version. Themes within same generation should be backwards
2951 compatible - theme with version 2 should work in phpMyAdmin requiring
2952 version 1. Themes with different generation are incompatible.</p>
2954 <p> If you do not want to use your own symbols and buttons, remove the
2955 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
2956 use the default icons and buttons (from the system-theme &quot;original&quot;).

3160 Since version 2.0.3, you can setup a central copy of phpMyAdmin for all

3169 <a href="#faq4_2">4.2 What's the preferred way of making phpMyAdmin secure against evil
3170 access.
3171 </a></h4>
3173 This depends on your system.<br />
3174 If you're running a server which cannot be accessed by other people, it's
3175 sufficient to use the directory protection bundled with your webserver
3176 (with Apache you can use <i>.htaccess</i> files, for example).<br />
3177 If other people have telnet access to your server, you should use
3178 phpMyAdmin's <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication features.
3179 <br /><br />
3180 Suggestions:
3181 </p>
3182 <ul>
3183 <li>
3184 Your <i>config.inc.php</i> file should be <tt>chmod 660</tt>.
3185 </li>
3186 <li>
3187 All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
3188 is a user whose password is only known to you, and apache is the
3189 group under which Apache runs.
3190 </li>
3191 <li>
3192 You should use PHP safe mode, to protect from other users that try
3193 to include your <i>config.inc.php</i> in their scripts.
3194 </li>
3195 </ul>

3198 <a href="#faq4_3">4.3 I get errors about not being able to include a file in
3199 <i>/lang</i> or in <i>/libraries</i>.
3200 </a></h4>
3202 Check <i>php.ini</i>, or ask your sysadmin to check it. The
3203 <tt>include_path</tt> must contain &quot;.&quot; somewhere in it, and
3204 <tt>open_basedir</tt>, if used, must contain &quot;.&quot; and

3219 <li>The username/password you specify in the login dialog are invalid.</li>
3220 <li>You have already setup a security mechanism for the
3221 phpMyAdmin-directory, eg. a .htaccess file. This would interfere with

3226 <a href="#faq4_5">4.5 Is it possible to let users create their own databases?</a></h4>
3228 <p> Starting with 2.2.5, in the user management page, you can enter a wildcard
3229 database name for a user (for example &quot;joe%&quot;),
3230 and put the privileges you want. For example,
3231 adding <tt>SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER</tt>
3232 would let a user create/manage his/her database(s).</p>

3238 and add a username between the <tt>'deny'</tt>/<tt>'allow'</tt> and
3239 <tt>'from'</tt> strings. Using the username wildcard of <tt>'%'</tt> would
3240 be a major benefit here if your installation is suited to using it. Then

3595 &quot;table_coords&quot; and &quot;pdf_pages&quot; have to be filled in.
3596 <br /><br />
3597 Then you need to think about your schema layout. Which tables will go on
3598 which pages?
3599 </p>
3600 <ul>
3601 <li>Select your database in the left frame.</li>
3602 <li>Choose &quot;Operations&quot; in the navigation bar at the top.</li>
3603 <li>Choose &quot;Edit <abbr title="Portable Document Format">PDF</abbr>
3604 Pages&quot; near the bottom of the page.</li>
3605 <li>Enter a name for the first <abbr title="Portable Document Format">PDF</abbr>
3606 page and click Go. If you like, you
3607 can use the &quot;automatic layout,&quot; which will put all your
3608 linked tables onto the new page.</li>
3609 <li>Select the name of the new page (making sure the Edit radio button
3610 is selected) and click Go.</li>
3611 <li>Select a table from the list, enter its coordinates and click Save.<br />
3612 Coordinates are relative; your diagram will
3613 be automatically scaled to fit the page. When initially placing tables
3614 on the page, just pick any coordinates -- say, 50x50. After clicking
3615 Save, you can then use the <a href="#wysiwyg">graphical editor</a> to
3616 position the element correctly.</li>
3617 <li>When you'd like to look at your <abbr title="Portable Document Format">PDF</abbr>,
3618 first be sure to click the Save
3619 button beneath the list of tables and coordinates, to save any changes
3620 you made there. Then scroll all the way down, select the
3621 <abbr title="Portable Document Format">PDF</abbr> options
3622 you want, and click Go.</li>
3623 <li>Internet Explorer for Windows may suggest an incorrect filename when
3624 you try to save a generated <abbr title="Portable Document Format">PDF</abbr>.
3625 When saving a generated <abbr title="Portable Document Format">PDF</abbr>, be
3626 sure that the filename ends in &quot;.pdf&quot;, for example
3627 &quot;schema.pdf&quot;. Browsers on other operating systems, and other
3628 browsers on Windows, do not have this problem.</li>
3629 </ul>
3631 <h4 id="faq6_9">
3632 <a href="#faq6_9">6.9 phpMyAdmin is changing the type of one of my
3633 columns!</a></h4>
3635 <p> No, it's MySQL that is doing

3640 <a href="#underscore">6.10 When creating a privilege, what happens with
3641 underscores in the database name?</a></h4>
3643 <p> If you do not put a backslash before the underscore, this is a wildcard
3644 grant, and the underscore means &quot;any character&quot;. So, if the
3645 database name is &quot;john_db&quot;, the user would get rights to john1db,
3646 john2db ...<br /><br />
3648 If you put a backslash before the underscore, it means that the database
3649 name will have a real underscore.</p>

3658 <a href="#faqexport">6.12 I want to understand some Export options.</a></h4>
3660 <p><b>Structure:</b></p>
3662 <ul><li>&quot;Add DROP TABLE&quot; will add a line telling MySQL to
3663 <a href="http://dev.mysql.com/doc/mysql/en/drop-table.html">drop the table</a>,
3664 if it already exists during the import. It does NOT drop the table after
3665 your export, it only affects the import file.</li>
3666 <li>&quot;If Not Exists&quot; will only create the table if it doesn't exist.
3667 Otherwise, you may get an error if the table name exists but has a
3668 different structure.</li>
3669 <li>&quot;Add AUTO_INCREMENT value&quot; ensures that AUTO_INCREMENT value
3670 (if any) will be included in backup.</li>
3671 <li>&quot;Enclose table and field names with backquotes&quot; ensures that
3672 field and table names formed with special characters are protected.</li>
3673 <li>&quot;Add into comments&quot; includes column comments, relations, and MIME
3674 types set in the pmadb in the dump as
3675 <abbr title="structured query language">SQL</abbr> comments (<i>/* xxx */</i>).
3676 </li>
3677 </ul>
3679 <p><b>Data:</b></p>
3681 <ul><li>&quot;Complete inserts&quot; adds the column names on every INSERT
3682 command, for better documentation (but resulting file is bigger).</li>
3683 <li>&quot;Extended inserts&quot; provides a shorter dump file by using only
3684 once the INSERT verb and the table name.</li>
3685 <li>&quot;Delayed inserts&quot; are best explained in the
3686 <a href="http://dev.mysql.com/doc/mysql/en/insert-delayed.html">MySQL manual</a>.
3687 </li>
3688 <li>&quot;Ignore inserts&quot; treats errors as a warning instead. Again,
3689 more info is provided in the
3690 <a href="http://dev.mysql.com/doc/mysql/en/insert.html">MySQL manual</a>,
3691 but basically with this selected, invalid values are adjusted and
3692 inserted rather than causing the entire statement to fail.</li>
3693 </ul>
3695 <h4 id="faq6_13">
3696 <a href="#faq6_13">6.13 I would like to create a database with a dot
3697 in its name.</a></h4>
3699 <p> This is a bad idea, because in MySQL the syntax &quot;database.table&quot;
3700 is the normal way to reference a database and table name. Worse, MySQL
3701 will usually let you create a database with a dot, but then you cannot
3702 work with it, nor delete it.</p>
3704 <h4 id="faqsqlvalidator">
3705 <a href="#faqsqlvalidator">6.14 How do I set up the
3706 <abbr title="structured query language">SQL</abbr> Validator?</a></h4>
3708 <p> To use it, you need a very recent version of PHP, 4.3.0 recommended, with
3709 <abbr title="Extensible Markup Language">XML</abbr>,
3710 <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
3711 <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
3712 On your system command line, run <tt>"pear install Net_Socket Net_URL
3713 HTTP_Request Mail_Mime Net_DIME SOAP"</tt> to get the necessary
3714 <abbr title="PHP Extension and Application Repository">PEAR</abbr> modules
3715 for usage.<br />
3716 On a more recent pear version, I had problems with the state of Net_DIME
3717 being beta, so this single command
3718 <tt>"pear -d preferred_state=beta install -a SOAP"</tt> installed all the
3719 needed modules.<br />
3720 If you use the Validator, you should be aware that any
3721 <abbr title="structured query language">SQL</abbr> statement you
3722 submit will be stored anonymously (database/table/column names,
3723 strings, numbers replaced with generic values). The Mimer
3724 <abbr title="structured query language">SQL</abbr>
3725 Validator itself, is &copy; 2001 Upright Database Technology.
3726 We utilize it as free SOAP service.</p>
3728 <h4 id="faq6_15">
3729 <a href="#faq6_15">6.15 I want to add a BLOB field and put an index on
3730 it, but MySQL says &quot;BLOB column '...' used in key specification without
3731 a key length&quot;.</a></h4>
3733 <p> The right way to do this, is to create the field without any indexes,
3734 then display the table structure and use the &quot;Create an index&quot;
3735 dialog. On this page, you will be able to choose your BLOB field, and
3736 set a size to the index, which is the condition to create an index on
3737 a BLOB field.</p>
3739 <h4 id="faq6_16">
3740 <a href="#faq6_16">6.16 How can I simply move in page with plenty
3741 editing fields?</a></h4>
3743 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
3744 with many editing fields (table structure changes, row editing, etc.)
3745 (must be enabled in configuration - see.
3746 <a href="#CtrlArrowsMoving" class="configrule">$cfg['CtrlArrowsMoving']</a>).
3747 You can also have a look at the directive
3748 <a href="#DefaultPropDisplay" class="configrule">$cfg['DefaultPropDisplay']</a>
3749 ('vertical') and see if this eases up editing for you.</p>
3751 <h4 id="faq6_17">
3752 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
3753 WTF is this feature then useful for?</a></h4>
3755 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
3756 on them. Otherwise you could just put a comment on the field. Because entering
3757 your own mimetype will cause serious syntax checking issues and validation,
3758 this introduces a high-risk false-user-input situation. Instead you have to
3759 initialize mimetypes using functions or empty mimetype definitions.<br />
3760 Plus, you have a whole overview of available mimetypes. Who knows all those
3761 mimetypes by heart so he/she can enter it at will?</p>
3763 <h4 id="faqbookmark">
3764 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
3765 can't I see any bookmarks below the query box? What is this variable for?
3766 </a></h4>
3768 <p> Any query you have executed can be stored as a bookmark on the page where the
3769 results are displayed. You will find a button labeled 'Bookmark this query'
3770 just at the end of the page.<br />
3771 As soon as you have stored a bookmark, it is related to the database you run
3772 the query on. You can now access a bookmark dropdown on each page, the query
3773 box appears on for that database.<br /><br />
3775 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
3776 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
3777 which is put into the <i>value</i> input box on the query box page will
3778 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
3779 aware of that you HAVE to create a valid query, otherwise your query won't be
3780 even able to be stored in the database.<br />
3781 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
3782 for your query will remain the way it is, but will be stripped of the /**/
3783 chars. So you can use:<br /><br />
3785 <code>/*, [VARIABLE] AS myname */</code><br /><br />
3787 which will be expanded to<br /><br />
3789 <code>, VARIABLE as myname</code><br /><br />
3791 in your query, where VARIABLE is the string you entered in the input box. If
3792 an empty string is provided, no replacements are made.<br /><br />
3794 A more complex example. Say you have stored this query:<br /><br />
3795 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
3796 <br /><br />
3798 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
3799 the full query will be:<br /><br />
3801 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
3802 <br /><br />
3804 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query.<br />
3805 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
3806 spaces inserted there
3807 will be later also inserted as spaces in your query and may lead to unexpected
3808 results especially when
3809 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
3810 Your initial query which is going to be stored as a bookmark has to yield at
3811 least one result row so
3812 you can store the bookmark. You may have that to work around using well
3813 positioned &quot;/**/&quot; comments.</p>
3815 <h4 id="faq6_19">
3816 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
3817 include exported table?</a></h4>
3819 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
3820 document should look like following one (assuming you have table
3821 exported in file <code>table.tex</code>):</p>
3823 <pre>
3824 \documentclass{article} % or any class you want
3825 \usepackage{longtable} % for displaying table

3832 <a href="#faq6_20">6.20 In MySQL 4, I see a lot of databases which are not mine, and cannot
3833 access them.
3834 </a></h4>
3836 <p> Upgrading to MySQL 4 usually gives users those global privileges: CREATE
3837 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
3838 enable users to see all the database names.
3839 See this <a href="http://bugs.mysql.com/179">bug report</a>.<br /><br />

3850 <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
3851 6.6</a> for an example. Then, if there are 200 values or less in the
3852 foreign table, a drop-down list of values will be available.
3853 You will see two lists of values, the first list containing the key
3854 and the display field, the second list containing the display field
3855 and the key. The reason for this is to be able to type the first
3856 letter of either the key or the display field.<br /><br />
3858 For 200 values or more, a distinct window will appear, to browse foreign
3859 key values and choose one.</p>

3880 <a href="#cfg_TempDir" class="configrule">$cfg['TempDir']</a> to
3881 place where web server user can write (for example <tt>'./tmp'</tt>) and
3882 install <abbr title="PHP Extension and Application Repository">PEAR</abbr>

3985 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
3986 great features have been written by other people and you too can help to
3987 make phpMyAdmin a useful tool.</p>
3989 <p> If you're planning to contribute source, please read the following
3990 information:</p>
3992 <ul><li>All files include <i>libraries/header.inc.php</i> (layout),.
3993 <i>libraries/common.lib.php</i> (common functions) and
3994 <i>config.inc.php</i>.<br />
3995 Only configuration data should go in <i>config.inc.php</i>. Please keep
3996 it free from other code.<br />
3997 Commonly used functions should be added to
3998 <i>libraries/common.lib.php</i> and more specific ones may be added
3999 within a library stored into the <i>libraries</i> sub-directory.</li>
4000 <li>Obviously, you're free to use whatever coding style you want. But
4001 please try to keep your code as simple as possible: beginners are
4002 using phpMyAdmin as an example application.<br />
4003 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4004 compliant on one hand, they fit the

4188 Original Credits of Version 2.1.0
4189 ---------------------------------
4191 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4192 to create a web-based interface to MySQL using PHP3. Although I have not
4193 used any of his source-code, there are some concepts I've borrowed from
4194 him. phpMyAdmin was created because Peter told me he wasn't going to
4195 further develop his (great) tool.
4196 Thanks go to
4197 - Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4198 code for the check when dropping a table or database. He also suggested
4199 that you should be able to specify the primary key on tbl_create.php3. To
4200 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4201 well as a bug-report. Plus many smaller improvements.
4202 - Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4203 were introduced in 1.3.0 (including quite significant ones like the
4204 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4205 bug-fixes and help.
4206 - Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4207 language-independent by outsourcing the strings to a separate file. He
4208 also contributed the French translation.
4209 - Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4210 tbl_select.php3, a feature to display only some fields from a table.
4211 - Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4212 functions in tbl_change.php3. He also added the
4213 &quot;Query by Example&quot; feature in 2.0.
4214 - Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4215 servers and is a regular contributor for bug-fixes.
4216 - Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4217 features for 2.0.6.
4218 The following people have contributed minor changes, enhancements, bugfixes
4219 or support for a new language:
4220 Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
4221 Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
4222 Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
4223 G. Wieggers.
4225 And thanks to everyone else who sent me email with suggestions, bug-reports
4226 and or just some feedback.
