91 <!-- INTRODUCTION -->
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.

146 </ul>
149 <p> Many people have difficulty
150 understanding the concept of user management with regards to phpMyAdmin. When
151 a user logs in to phpMyAdmin, that username and password are passed directly
152 to MySQL. phpMyAdmin does no account management on its own (other than
153 allowing one to manipulate the MySQL user account information); all users
154 must be valid MySQL users.</p>
163 <!-- INSTALLATION -->
171 </ol>
174 phpMyAdmin does not apply any special security methods to the MySQL database
175 server. It is still the system administrator's job to grant permissions on
177 be used for this.
178 </p>
186 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
187 before uploading them to your server, as PHP seems not to like
192 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
193 Downloads page. Some kits contain only the English messages,
194 others contain all languages in UTF-8 format (this should be fine
195 in most situations), others contain all
196 languages and all character sets. We'll assume you chose a kit whose
198 </li>
199 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
201 document root. If you don't have direct access to your document root,
202 put the files in a directory on your local machine, and, after step 4,
203 transfer the directory on your web server using, for example, ftp.</li>
204 <li>Ensure that all the scripts have the appropriate owner (if PHP is
205 running in safe mode, having some scripts with an owner different
206 from the owner of other scripts will be a
211 <li>Now you must configure your installation. There are two methods that
212 can be used. Traditionally, users have hand-edited a copy of
214 provided for those who prefer a graphical installation. Creating a
215 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
216 <ul><li>To manually create the file, simply use your text editor to
219 file) in the main (top-level) phpMyAdmin directory (the one
223 default value is okay for a particular setting, there is no
225 few directives to get going, a simple configuration may look
226 like this:
227 <pre>
228 <?php
229 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
231 $i=0;
232 $i++;
233 $cfg['Servers'][$i]['auth_type'] = 'cookie';
234 ?>
235 </pre>
236 Or, if you prefer to not be prompted every time you log in:
237 <pre>
238 <?php
240 $i=0;
241 $i++;
242 $cfg['Servers'][$i]['user'] = 'root';
243 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
244 $cfg['Servers'][$i]['auth_type'] = 'config';
245 ?>
246 </pre>
247 For a full explanation of possible configuration values, see the
253 directory. This is a security measure. On a Linux/Unix system you
254 can use the following commands:
255 <pre>
256 cd phpMyAdmin
257 mkdir config # create directory for saving
258 chmod o+rw config # give it world writable permissions
259 </pre>
260 And to edit an existing configuration, copy it over first:
261 <pre>
262 cp config.inc.php config/ # copy current configuration for editing
263 chmod o+w config/config.inc.php # give it world writable permissions
264 </pre>
265 On other platforms, simply create the folder and ensure that your
274 the webserver does not have the proper permissions you may see the
276 config/</tt> directory exists and has the proper permissions -
278 and upload (via FTP or some similar means) to the proper location.<br /><br />
280 Once the file has been saved, it must be moved out of the <tt>
281 config/</tt> directory and the permissions must be reset, again
282 as a security measure:
283 <pre>
284 mv config/config.inc.php . # move file to current directory
285 chmod o-rw config.inc.php # remove world read and write permissions
286 rm -rf config # remove not needed directory
287 </pre>
288 Now the file is ready to be used. You can choose to review or edit
289 the file with your favorite editor, if you prefer to set some
290 advanced options which the setup script does not provide.</li></ul></li>
291 <li>If you are using the
293 protect the phpMyAdmin installation directory because using
294 config does not require a user to
295 enter a password to access the phpMyAdmin installation. Use of an alternate
296 authentication method is recommended, for example with
304 in your browser. phpMyAdmin should now display a welcome screen
305 and your databases, or a login dialog if using
307 authentication mode.</li>
310 Apache you can use supplied .htaccess file in that folder, for other
311 webservers, you should configure this yourself. Such configuration
312 prevents from possible path exposure and cross side scripting
313 vulnerabilities that might happen to be found in that code.</li>
314 <li>
315 It is generally good idea to protect public phpMyAdmin installation
316 against access by robots as they usually can not do anything good

326 <p> For a whole set of new features (bookmarks, comments,
328 tracking mechanism,
330 transformation, etc.) you need to create a set of special tables. Those
331 tables can be located in your own database, or in a central database for a
332 multi-user installation (this database would then be accessed by the
333 controluser, so no other user should have rights to it).</p>
344 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
345 that you may need special (administrator) privileges to create the database
346 and tables, and that the script may need some tuning, depending on the
347 database name.</p>

359 unpacked one. Configuration files from old versions may
360 require some tweaking as some options have been changed or removed; in

368 is version-specific.</p>
371 version 5.x or newer and if you use the phpMyAdmin configuration storage,
372 you should run the SQL script found in
379 where you want to give users access to their own database and don't want
380 them to play around with others.<br />
381 Nevertheless be aware that MS Internet Explorer seems to be really buggy
385 that your user/password pair are not in clear in the configuration file.
386 </li>
389 authentication modes are more secure: the MySQL login information does
390 not need to be set in the phpMyAdmin configuration file (except possibly
392 However, keep in mind that the password travels in plain text, unless
393 you are using the HTTPS protocol.<br />

544 web applications.<br /><br />
545 When Swekey authentication is activated, phpMyAdmin requires the
546 users's Swekey to be plugged before entering the login page (currently
547 supported for cookie authentication mode only). Swekey Authentication is

947 Since release 2.3.0 you can describe, in a special 'table_info'
948 table, which column is to be displayed as a tool-tip when moving the
949 cursor over the corresponding key.<br />
950 This configuration variable will hold the name of this special
951 table. To allow the usage of this functionality:
953 <li>put the table name in
955 'pma_table_info')</li>

996 Starting with release 2.5.0, comments are consequently used on the table
997 property pages and table browse view, showing up as tool-tips above the
998 column name (properties page) or embedded within the header of table in
999 browse view. They can also be shown in a table dump. Please see the
1000 relevant configuration directives later on.<br /><br />
1002 Also new in release 2.5.0 is a MIME-transformation system which is also
1004 Transformations</a> for further information. To use the
1005 MIME-transformation system, your column_info table has to have the three
1006 new columns 'mimetype', 'transformation', 'transformation_options'.

1036 don't want to use a table-based history, you can use the JavaScript-based
1037 history. Using that, all your history items are deleted when closing the
1038 window.<br /><br />
1040 Using
1042 you can specify an amount of history items you want to have on hold. On
1043 every login, this list gets cut to the maximum amount.<br /><br />

1061 Since release 3.5.0 you can show recently used tables in the left navigation frame.
1062 It helps you to jump across table directly, without the need to select the database,
1063 and then select the table. Using
1065 you can configure the maximum number of recent tables shown. When you select a table
1066 from the list, it will jump to the page specified in
1067 <a href="#cfg_LeftDefaultTabTable" class="configrule">$cfg['LeftDefaultTabTable']</a>.<br/><br/>
1069 Without configuring the storage, you can still access the recently used tables,

1103 Since release 3.3.x a tracking mechanism is available.
1105 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1106 and data definition statements. After enabling it you can create versions of tables.
1107 <br/><br/>
1108 The creation of a version has two effects:
1110 <ul>
1112 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1113 </ul>
1115 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1116 For the report you can use filters, for example you can get a list of statements within a date range.
1117 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1118 In addition you can export the (filtered) report to a file or to a temporary database.

1950 row on a horizontal line, the second rotates the headers by 90

1961 The HeaderFlipType can be set to 'auto', 'css' or 'fake'. When using

1963 CSS. The CSS transformation currently works only in Internet
1964 Explorer.If set to 'fake' PHP does the transformation for you, but of
1965 course this does not look as good as CSS. The 'auto' option enables

2136 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2137 or icon is always displayed on the left panel. If JavaScript is enabled in
2138 your browser, a click on this opens a distinct query window, which is
2139 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2140 changes to display a query box.<br /><br />

2167 updated when you click on a new table/db to browse and will focus if
2168 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2169 the query window by checking the box "Do not overwrite this query from
2170 outside the window" below the query textarea. Then you can browse
2171 tables/databases in the background without losing the contents of the

2385 <!-- TRANSFORMATIONS -->
2391 </ol>
2395 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2397 section</a> on how to do so.</p>
2399 <p> You can apply different transformations to the contents of each column. The
2400 transformation will take the content of each column and transform it with
2401 certain rules defined in the selected transformation.</p>
2403 <p> Say you have a column 'filename' which contains a filename. Normally you would
2404 see in phpMyAdmin only this filename. Using transformations you can transform
2405 that filename into a HTML link, so you can click inside of the phpMyAdmin
2406 structure on the column's link and will see the file displayed in a new browser
2407 window. Using transformation options you can also specify strings to
2408 append/prepend to a string or the format you want the output stored in.</p>
2410 <p> For a general overview of all available transformations and their options,
2411 you can consult your
2412 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2413 installation.</p>
2415 <p> For a tutorial on how to effectively use transformations, see our
2417 the official phpMyAdmin homepage.</p>
2421 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2422 clicking on the 'Structure' link for a table). There click on
2423 "Change" (or change icon) and there you will see three new
2424 fields at
2425 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2426 'Transformation options'.</p>
2428 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2429 that corresponds to the column's contents. Please note that
2430 transformations are inactive as long as no MIME-type is selected.</li>
2432 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2433 hopefully growing amount of pre-defined transformations. See below for information on
2434 how to build your own transformation.<br />
2436 There are global transformations and mimetype-bound transformations. Global transformations
2437 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2438 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2439 transformations which operate on the main mimetype (like 'image'), which will most likely
2440 take the subtype into regard, and those who only operate on a
2441 specific subtype (like 'image/jpeg').<br />
2443 You can use transformations on mimetypes for which the function was not defined for. There
2444 is no security check for you selected the right transformation, so take care of what the
2445 output will be like.</li>
2447 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2448 transform-function specific options here. Usually the transforms can operate with default
2449 options, but it is generally a good idea to look up the overview to see which options are
2450 necessary.<br />
2452 Much like the ENUM/SET-Fields, you have to split up several options using the format
2453 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2454 parsed as an array, leaving the first value the first element in the array, and so
2455 forth.<br />
2457 If you want to specify a MIME character set you can define it in the transformation_options.
2458 You have to put that outside of the pre-defined options of the specific mime-transform,
2460 for which you can specify 2 options and you want to append a character set, enter "'first
2461 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2463 </ul>
2467 <p> All mimetypes and their transformations are defined through single files in
2468 the directory 'libraries/transformations/'.</p>
2470 <p> They are stored in files to ease up customization and easy adding of new
2471 transformations.</p>
2473 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2474 always work. It makes no sense to apply a transformation to a mimetype the
2475 transform-function doesn't know to handle.</p>
2477 <p> One can, however, use empty mime-types and global transformations which should work
2478 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2479 for, but pay attention to option usage as well as what the transformation does to your
2480 column.</p>
2482 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2483 any other transform function and provides some basic functions.</p>
2485 <p> There are 5 possible file names:</p>
2487 <ol><li>A mimetype+subtype transform:<br /><br />
2489 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2491 Please not that mimetype and subtype are separated via '_', which shall
2492 not be contained in their names. The transform function/filename may
2493 contain only characters which cause no problems in the file system as
2494 well as the PHP function naming convention.<br /><br />
2496 The transform function will the be called
2497 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2499 <b>Example:</b><br /><br />
2501 <tt>text_html__formatted.inc.php</tt><br />
2502 <tt>PMA_transform_text_html__formatted()</tt></li>
2504 <li>A mimetype (w/o subtype) transform:<br /><br />
2506 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2508 Please note that there are no single '_' characters.
2509 The transform function/filename may contain only characters which cause
2510 no problems in the file system as well as the PHP function naming
2511 convention.<br /><br />
2513 The transform function will the be called
2514 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2516 <b>Example:</b><br /><br />
2518 <tt>text__formatted.inc.php</tt><br />
2519 <tt>PMA_transform_text__formatted()</tt></li>
2521 <li>A mimetype+subtype without specific transform function<br /><br />
2523 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2525 Please note that there are no '__' characters in the filename. Do not
2526 use special characters in the filename causing problems with the file
2527 system.<br /><br />
2529 No transformation function is defined in the file itself.<br /><br />
2531 <b>Example:</b><br /><br />
2533 <tt>text_plain.inc.php</tt><br />
2534 (No function)</li>
2536 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2538 <tt>[mimetype].inc.php</tt><br /><br />
2540 Please note that there are no '_' characters in the filename. Do not use
2541 special characters in the filename causing problems with the file system.
2542 <br /><br />
2544 No transformation function is defined in the file itself.<br /><br />
2546 <b>Example:</b><br /><br />
2548 <tt>text.inc.php</tt><br />
2549 (No function)</li>
2551 <li>A global transform function with no specific mimetype<br /><br />
2553 <tt>global__[transform].inc.php</tt><br /><br />
2555 The transform function will the be called
2556 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2558 <b>Example:</b><br /><br />
2560 <tt>global__formatted</tt><br />
2561 <tt>PMA_transform_global__formatted()</tt></li>
2562 </ol>
2564 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2565 transform function.</p>
2567 <p> All filenames containing no '__' in themselves are not shown as valid transform
2568 functions in the dropdown.</p>
2570 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2571 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2572 without a transform function.</p>
2574 <p> To create a new transform function please see
2575 <tt>libraries/transformations/template_generator.sh</tt>.
2576 To create a new, empty mimetype please see
2577 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2579 <p> A transform function always gets passed three variables:</p>
2581 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2582 you want to transform.</li>
2583 <li><b>$options</b> - Contains any user-passed options to a transform function
2584 as an array.</li>
2585 <li><b>$meta</b> - Contains an object with information about your column.
2586 The data is drawn from the output of the
2588 function. This means, all object properties described on the
2590 available in this variable and can be used to transform a column accordingly
2591 to unsigned/zerofill/not_null/... properties.<br />
2592 The $meta->mimetype variable contains the original MIME-type of the
2593 column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2594 </ol>
2596 <p> Additionally you should also provide additional function to provide
2597 information about the transformation to the user. This function should
2598 have same name as transformation function just with appended
2599 <code>_info</code> suffix. This function accepts no parameters and returns
2600 array with information about the transformation. Currently following keys

2679 <p> This seems to be a PWS bug. Filippo Simoncini found a workaround (at this
2680 time there is no better fix): remove or comment the <tt>DOCTYPE</tt>

2690 <p> These features are based on the <tt>gzencode()</tt> and <tt>bzcompress()</tt>
2691 PHP functions to be more independent of the platform (Unix/Windows, Safe Mode
2692 or not, and so on). So, you must have Zlib/Bzip2
2693 support (<tt>--with-zlib</tt> and <tt>--with-bz2</tt>).<br /></p>
2697 an error about safe mode being in effect.</a></h4>
2699 <p> Your uploaded file is saved by PHP in the "upload dir", as
2700 defined in <i>php.ini</i> by the variable <tt>upload_tmp_dir</tt> (usually
2701 the system default is <i>/tmp</i>).<br />
2702 We recommend the following setup for Apache servers running in safe mode,
2703 to enable uploads of files while being reasonably secure:</p>
2705 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2706 <li>give ownership to the Apache server's user.group:
2707 <tt>chown apache.apache /tmp/php</tt></li>
2708 <li>give proper permission: <tt>chmod 600 /tmp/php</tt></li>
2709 <li>put <tt>upload_tmp_dir = /tmp/php</tt> in <i>php.ini</i></li>

2730 uploading a file from the query box.</a></h4>
2732 <p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir
2733 restrictions. However you need to create temporary directory and

2756 were named <tt>user</tt> and <tt>password</tt>. Please modify your column
2757 names to align with current standards.</p>
2762 </h4>
2764 <p> Starting with version 2.7.0, the import engine has been re–written and these
2765 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2766 to take advantage of the new import features.</p>
2768 <p> The first things to check (or ask your host provider to check) are the
2769 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2770 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2771 All of these three settings limit the maximum size of data that can be
2772 submitted and handled by PHP. One user also said that post_max_size
2773 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2775 There exist several workarounds if your upload is too big or your
2776 hosting provider is unwilling to change the settings:</p>
2779 feature. This allows one to
2780 upload a file to the server via scp, ftp, or your favorite file transfer

2786 or any third party applications, but are aware of users having success
2787 with it.</li>
2788 <li>If you have shell (command line) access, use MySQL to import the files
2789 directly. You can do this by issuing the "source" command from
2790 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2791 </ul>
2795 support?</a></h4>
2797 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2798 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
2799 connect to your MySQL server using PHP's classic
2802 is available in php 5.0. The latter one should be used unless you have a
2803 good reason not to do so.<br />
2804 When compiling PHP, we strongly recommend that you manually link the MySQL
2805 extension of your choice to a MySQL client library of at least the same
2806 minor version since the one that is bundled with some PHP distributions is
2809 MariaDB is also supported (versions 5.1 and 5.2 were tested).

2817 <p> You tried to access MySQL with an old MySQL client library. The version of
2818 your MySQL client library can be checked in your phpinfo() output.
2819 In general, it should have at least the same minor version as your server

2848 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2849 "MySQL extension". This extension may be part of the PHP
2850 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2851 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2852 to load the extension but failed.<br /><br />
2854 Usually, the problem is solved by installing a software package called
2855 "PHP-MySQL" or something similar.</p>

2875 <p> This happens because the MySQL directive <tt>lower_case_table_names</tt>
2876 defaults to 1 (<tt>ON</tt>) in the Win32 version of MySQL. You can change
2877 this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
2878 Just edit your <tt>my.ini</tt> file that should be located in your Windows
2879 directory and add the following line to the group [mysqld]:</p>
2881 <pre>set-variable = lower_case_table_names=0</pre>
2883 <p> Next, save the file and restart the MySQL service. You can always check the
2884 value of this directive using the query</p>

2902 </pre>
2904 <p> as this version of mod_gzip on Apache (Windows) has problems handling
2905 PHP scripts. Of course you have to restart Apache.</p>
2910 I get the error "No input file specified" when trying to
2911 run phpMyAdmin.</a></h4>
2913 <p> This is a permission problem. Right-click on the phpmyadmin folder

2926 PHP 5.0.0.</p>
2930 message 'Errorcode: 13'. What does this mean?</a></h4>
2932 <p> This can happen due to a MySQL bug when having database / table names with
2933 upper case characters although <tt>lower_case_table_names</tt> is set to 1.
2934 To fix this, turn off this directive, convert all database and table names
2935 to lower case and turn it on again. Alternatively, there's a bug-fix
2936 available starting with MySQL 3.23.56 / 4.0.11-gamma.</p>
2940 and the columns are duplicated.</a></h4>
2942 <p> It is possible to configure Apache in such a way that PHP has problems
2943 interpreting .php files.</p>
2945 <p> The problems occur when two different (and conflicting) set of directives
2946 are used:</p>
2948 <pre>
2949 SetOutputFilter PHP

2957 <p> In the case we saw, one set of directives was in
2958 <tt>/etc/httpd/conf/httpd.conf</tt>, while
2959 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2960 The recommended way is with <tt>AddType</tt>, so just comment out
2961 the first set of lines and restart Apache:</p>
2963 <pre>
2964 #SetOutputFilter PHP
2965 #SetInputFilter PHP

2971 <p> This problem is known to happen when the server is running Turck MMCache
2972 but upgrading MMCache to version 2.3.21 solves the problem.</p>
2977 <p>Yes.</p>

3011 the order of the server paragraph in <tt>config.inc.php</tt>.
3012 Table and script parts are optional. If you want
3013 http://server/phpMyAdmin/database[/table][/script] <abbr title="Uniform Resource Locator">URL</abbr>s, you need to do
3014 some configuration. Following lines apply only for <a
3016 that you have enabled some features within global configuration. You need
3017 <code>Options FollowSymLinks</code> and <code>AllowOverride
3018 FileInfo</code> enabled for directory where phpMyAdmin is installed and
3019 you need mod_rewrite to be enabled. Then you just need to create following
3020 <code>.htaccess</code> file in root folder of phpMyAdmin installation
3021 (don't forget to change directory name inside of it):</p>

3053 password encryption in cookie auth doesn't work.</a></h4>
3055 <p> If your cluster consist of different architectures, PHP code used for
3056 encryption/decryption won't work correct. This is caused by use of
3057 pack/unpack functions in code. Only solution is to use mcrypt extension
3058 which works fine in this case.</p>
3063 <p> Yes but the default configuration values of Suhosin are known to cause
3064 problems with some operations, for example editing a table with many
3065 columns and no primary key or with textual primary key.
3066 </p>
3067 <p>
3068 Suhosin configuration might lead to malfunction in some cases and it can
3069 not be fully avoided as phpMyAdmin is kind of application which needs to
3070 transfer big amounts of columns in single HTTP request, what is something
3071 what Suhosin tries to prevent. Generally all
3072 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3073 <code>suhosin.get.*</code> directives can have negative effect on
3074 phpMyAdmin usability. You can always find in your error logs which limit
3075 did cause dropping of variable, so you can diagnose the problem and adjust
3076 matching configuration variable.
3077 </p>
3078 <p>
3079 The default values for most Suhosin configuration options will work in most
3080 scenarios, however you might want to adjust at least following parameters:

3083 <ul>
3084 <li><a href="http://www.hardened-php.net/suhosin/configuration.html#suhosin.request.max_vars">suhosin.request.max_vars</a> should be increased (eg. 2048)</li>

3102 behavior?</a></h4>
3104 <p> Be sure that you have enabled <tt>SSLOptions</tt> and <tt>StdEnvVars</tt>
3105 in your Apache configuration. See <a href="http://httpd.apache.org/docs/2.0/mod/mod_ssl.html#ssloptions">http://httpd.apache.org/docs/2.0/mod/mod_ssl.html#ssloptions</a>.</p>
3108 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>
3110 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />
3111 Example from the Apache 2.2 documentation:</p>
3112 <pre>
3113 ProxyPass /mirror/foo/ http://backend.example.com/
3114 ProxyPassReverse /mirror/foo/ http://backend.example.com/
3115 ProxyPassReverseCookieDomain backend.example.com public.example.com
3116 ProxyPassReverseCookiePath / /mirror/foo/
3117 </pre>
3119 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3120 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
3121 This is not specific to phpmyadmin, it's just the behavior of Apache.

3124 <pre>
3125 ProxyPass /mirror/foo/ http://backend.example.com/~user/phpmyadmin

3159 <p> Either there is an error with your PHP setup or your username/password is

3162 into PHP.</p>
3166 connect to local MySQL server through socket '/tmp/mysql.sock'
3167 (111) ..." is displayed. What can I do?</a></h4>
3169 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3171 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3172 In your <i>php.ini</i> you will find a line</p>
3174 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3176 <p> change it to</p>
3178 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3180 <p> Then restart apache and it will work.</p>
3182 <p> Here is a fix suggested by Brad Ummer:</p>
3184 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3185 To do this, telnet to your server and go to the MySQL bin directory. In
3186 this directory there should be a file named <i>mysqladmin</i>. Type
3187 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3188 info about your MySQL server, including the socket
3189 (<i>/tmp/mysql.sock</i>, for example).</li>
3190 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3191 phpMyAdmin, you need to complete the socket information in the
3192 <i>config.inc.php</i>.<br />
3193 For example:
3195 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3196 <br /><br />
3198 Please also make sure that the permissions of this file allow to be readable
3199 by your webserver (i.e. '0755').</li>

3231 <p> When you are using a port on your localhost, which you redirect via
3232 port-forwarding to another host, MySQL is not resolving the localhost
3233 as expected.<br />
3234 Erik Wasser explains: The solution is: if your host is "localhost"
3235 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3236 connection for speeding up things. And that doesn't work in this configuration
3237 with port forwarding.<br />

3250 structure, because this is the system theme used by phpMyAdmin.
3251 "original" contains all images and styles, for backwards
3252 compatibility and for all themes that would not include images or css-files.
3253 <br /><br />
3256 is enabled, you can select your favorite theme on the main page. Your
3257 selected theme will be stored in a cookie.<br /><br /></p>
3259 <p> To create a theme:</p>
3261 <ul><li>make a new subdirectory (for example "your_theme_name") under
3263 (by default <tt>themes</tt>)</li>
3264 <li>copy the files and directories from "original" to
3265 "your_theme_name"</li>
3266 <li>edit the css-files in "your_theme_name/css"</li>
3267 <li>put your new images in "your_theme_name/img"</li>
3268 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
3269 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
3270 contain your chosen theme name, that will be visible in user interface</li>
3271 <li>make a new screenshot of your theme and save it under
3272 "your_theme_name/screen.png"</li>
3273 </ul>
3275 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3276 theme verbose name, theme generation and theme version. These versions and
3277 generations are enumerated from 1 and do not have any direct dependence on
3278 phpMyAdmin version. Themes within same generation should be backwards
3279 compatible - theme with version 2 should work in phpMyAdmin requiring
3280 version 1. Themes with different generation are incompatible.</p>
3282 <p> If you do not want to use your own symbols and buttons, remove the
3283 directory "img" in "your_theme_name". phpMyAdmin will
3284 use the default icons and buttons (from the system-theme "original").
3285 </p>
3289 what can I do?</a></h4>
3291 <p> Here are a few points to check:</p>
3293 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3295 directive empty. See also
3297 </li>
3298 <li>Maybe you have a broken PHP installation or you need to upgrade
3299 your Zend Optimizer. See
3301 http://bugs.php.net/bug.php?id=31134</a>.
3302 </li>
3303 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3304 set to the default (200) or another low value, you could get this
3305 error if your table has a high number of columns. Adjust this setting
3306 accordingly. (Thanks to Klaus Dorninger for the hint).
3307 </li>
3308 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3309 of ";" will cause this error. Replace it with "&;".
3310 </li>
3312 you might want to increase
3314 </li>
3315 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3316 </li>
3317 </ul>
3322 <p> To be able to see a progress bar during your uploads, your server must
3325 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3326 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3333 who logged out can not log in again in with the same nick.</a></h4>
3335 <p> This is related to the authentication mechanism (protocol) used by
3336 phpMyAdmin. To bypass this problem: just close all the opened
3337 browser windows and then go back to phpMyAdmin. You should be able to
3338 log in again.</p>
3342 limit error or a time limit error.</a></h4>
3344 <p> Compressed dumps are built in memory and because of this are limited to
3345 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3346 using
3348 (enabled by default). Zip exports can not be handled this way, so if you need
3349 Zip files for larger dump, you have to use another way.</p>
3353 when I rename a table or a column.</a></h4>
3355 <p> This is an InnoDB bug, see <a href="http://bugs.mysql.com/bug.php?id=21704">http://bugs.mysql.com/bug.php?id=21704</a>.</p>
3359 bundled with the MySQL server distribution.</a></h4>
3361 <p> The problem is that older versions of <code>mysqldump</code> created invalid comments like this:</p>
3363 <pre>
3364 -- MySQL dump 8.22
3365 --
3366 -- Host: localhost Database: database
3367 ---------------------------------------------------------
3368 -- Server version 3.23.54
3369 </pre>
3371 <p> The invalid part of the code is the horizontal line made of dashes that
3372 appears once in every dump created with mysqldump. If you want to run your
3373 dump you have to turn it into valid MySQL. This means, you have to add a
3374 whitespace after the first two dashes of the line or add a # before it:
3375 <br />
3376 <code>
3377 -- -------------------------------------------------------<br />
3378 </code>
3379 or<br />
3380 <code>
3381 #---------------------------------------------------------
3382 </code>
3383 </p>
3390 <p> Please note that you should not use the separating string multiple times
3391 without any characters between them, or at the beginning/end of your table
3392 name. If you have to, think about using another TableSeparator or disabling
3393 that feature</p>
3398 <p> In Relation view, being able to choose a table in another database,
3399 or having more than one index column in the foreign key.<br /><br/>
3400 In Query-by-example (Query), automatic generation of the query
3401 LEFT JOIN from the foreign table.<br /><br/>
3402 </p>
3406 I get series of errors like "Warning: unable to parse url". How
3407 can this be fixed?</a></h4>
3408 <p>
3409 Your table neither have a primary key nor an unique one, so we must use a
3410 long expression to identify this row. This causes problems to parse_url
3411 function. The workaround is to create a primary or unique key.
3412 <br />
3413 </p>
3417 a MIME-Transformation onto!</a></h4>
3419 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3420 nested forms can be put inside the table where phpMyAdmin displays the results.
3421 You can, however, use any form inside of a table if keep the parent
3422 form-container with the target to tbl_row_delete.php and just put your own
3423 input-elements inside. If you use a custom submit input field, the form will
3424 submit itself to the displaying page again, where you can validate the
3425 $HTTP_POST_VARS in a transformation.
3427 For a tutorial on how to effectively use transformations, see our
3429 on the official phpMyAdmin-homepage.</p>
3433 MySQL server</a></h4>
3435 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3438 http://dev.mysql.com/doc/mysql/en/ansi-mode.html</a>). Most important of all,
3439 the quote-character (") is interpreted as an identifier quote character and
3440 not as a string quote character, which makes many internal phpMyAdmin
3442 statements. There is no workaround to this behaviour. News to this item will
3443 be posted in Bug report
3444 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>

3449 more that one column with the same value
3450 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3451 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3453 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3454 can use it for the Edit and Delete links.</p>
3459 <p> phpMyAdmin uses a quick method to get the row count, and this method
3460 only returns an approximate count in the case of InnoDB tables. See
3462 a way to modify those results, but
3463 this could have a serious impact on performance.</p>

3480 This has been a known limitation of phpMyAdmin since the beginning and
3481 it's not likely to be solved in the future.

3484 <!-- Begin: Excel import limitations -->
3487 <a href="#faq3_15">3.15 When I import an Excel spreadsheet, some cells with calculations do not display correctly.</a></h4>
3488 <p>
3489 phpMyAdmin uses the <a href="http://www.codeplex.com/PHPExcel/">PHPExcel</a> library to parse Excel XLS and XLSX spreadsheets.
3490 Therefore, any limitations that are listed on their page regarding Excel calculations will also apply here.
3491 <br /><br />
3492 PHPExcel will be kept up to date so as to make all improvements available to phpMyAdmin users.

3496 <a href="#faq3_16">3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import it, nothing happens.</a></h4>
3497 <p>
3498 Since Excel XLSX workbooks are already compressed, there is often times only a small benefit from compressing them yet again.
3499 Support for compressed Excel XLSX and XLS workbooks may be added in the future.
3500 </p>
3503 <a href="#faq3_17">3.17 When I import an Excel spreadsheet, my custom cell types are not represented as they are in Excel.</a></h4>
3504 <p>
3505 Excel's internal representation of custom cell types is rather muddled (especially in Excel 97-2003 binary XLS files). If possible,
3506 consider using a built-in type. These are almost always guarenteed to import correctly.
3507 </p>
3509 <!-- End: Excel import limitations -->
3510 <!-- Begin: CSV import limitations -->
3513 <a href="#faq3_18">3.18 When I import a CSV file that contains multiple tables, they are lumped together into a single table.</a></h4>
3514 <p>
3515 There is no reliable way to differetiate tables in CSV format. For the time being, you will have to break apart CSV files containing multiple tables.

3519 <!-- Begin: Import type-detection limitations -->
3522 <a href="#faq3_19">3.19 When I import a file and have phpMyAdmin determine the appropriate data structure it only uses int, decimal, and varchar types.</a></h4>
3523 <p>
3524 Currently, the import type-detection system can only assign these MySQL types to columns. In future, more will likely be added but for the time being
3525 you will have to edit the structure to your liking post-import.
3526 <br /><br />
3527 Also, you should note the fact that phpMyAdmin will use the size of the largest item in any given column as the column size for the appropriate type. If you
3528 know you will be adding larger items to that column then you should manually adjust the column sizes accordingly. This is done for the sake of efficiency.

3975 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3976 <p>
3979 <br /><br />
3980 Then you need to think about your schema layout. Which tables will go on
3981 which pages?
3982 </p>
3983 <ul>
3989 page and click Go. If you like, you
3991 linked tables onto the new page.</li>
3992 <li>Select the name of the new page (making sure the Edit radio button
3993 is selected) and click Go.</li>
3995 Coordinates are relative; your diagram will
3996 be automatically scaled to fit the page. When initially placing tables
3997 on the page, just pick any coordinates -- say, 50x50. After clicking
3999 position the element correctly.</li>
4001 first be sure to click the Save
4002 button beneath the list of tables and coordinates, to save any changes
4003 you made there. Then scroll all the way down, select the
4005 you want, and click Go.</li>
4006 <li>Internet Explorer for Windows may suggest an incorrect filename when
4011 browsers on Windows, do not have this problem.</li>
4012 </ul>
4016 columns!</a></h4>
4018 <p> No, it's MySQL that is doing
4024 underscores in the database name?</a></h4>
4026 <p> If you do not put a backslash before the underscore, this is a wildcard
4029 john2db ...<br /><br />
4031 If you put a backslash before the underscore, it means that the database
4032 name will have a real underscore.</p>
4036 statistics pages?</a></h4>
4047 if it already exists during the import. It does NOT drop the table after
4048 your export, it only affects the import file.</li>
4050 Otherwise, you may get an error if the table name exists but has a
4051 different structure.</li>
4053 (if any) will be included in backup.</li>
4055 column and table names formed with special characters are protected.</li>
4057 types set in the pmadb in the dump as
4059 </li>
4060 </ul>
4065 command, for better documentation (but resulting file is bigger).</li>
4067 once the INSERT verb and the table name.</li>
4070 </li>
4072 more info is provided in the
4074 but basically with this selected, invalid values are adjusted and
4075 inserted rather than causing the entire statement to fail.</li>
4076 </ul>
4080 in its name.</a></h4>
4083 is the normal way to reference a database and table name. Worse, MySQL
4084 will usually let you create a database with a dot, but then you cannot
4085 work with it, nor delete it.</p>
4091 <p>
4092 To use SQL Validator, you need PHP with
4098 module.
4099 </p>
4101 <p>
4107 usage.
4108 </p>
4110 <p>
4111 If you use the Validator, you should be aware that any
4113 submit will be stored anonymously (database/table/column names,
4114 strings, numbers replaced with generic values). The Mimer
4117 We utilize it as free SOAP service.
4118 </p>
4122 it, but MySQL says "BLOB column '...' used in key specification without
4125 <p> The right way to do this, is to create the column without any indexes,
4127 dialog. On this page, you will be able to choose your BLOB column, and
4128 set a size to the index, which is the condition to create an index on
4129 a BLOB column.</p>
4133 editing fields?</a></h4>
4135 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4136 with many editing fields (table structure changes, row editing, etc.).
4137 You can also have a look at the directive
4139 ('vertical') and see if this eases up editing for you.</p>
4143 WTF is this feature then useful for?</a></h4>
4145 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4146 on them. Otherwise you could just put a comment on the column. Because entering
4147 your own mimetype will cause serious syntax checking issues and validation,
4148 this introduces a high-risk false-user-input situation. Instead you have to
4149 initialize mimetypes using functions or empty mimetype definitions.<br />
4150 Plus, you have a whole overview of available mimetypes. Who knows all those
4151 mimetypes by heart so he/she can enter it at will?</p>
4155 can't I see any bookmarks below the query box? What is this variable for?
4156 </a></h4>
4158 <p> Any query you have executed can be stored as a bookmark on the page where the
4159 results are displayed. You will find a button labeled 'Bookmark this query'
4160 just at the end of the page.<br />
4161 As soon as you have stored a bookmark, it is related to the database you run
4162 the query on. You can now access a bookmark dropdown on each page, the query
4163 box appears on for that database.<br /><br />
4165 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4169 aware of that you HAVE to create a valid query, otherwise your query won't be
4170 even able to be stored in the database.<br />
4172 for your query will remain the way it is, but will be stripped of the /**/
4173 chars. So you can use:<br /><br />
4177 which will be expanded to<br /><br />
4181 in your query, where VARIABLE is the string you entered in the input box. If
4182 an empty string is provided, no replacements are made.<br /><br />
4184 A more complex example. Say you have stored this query:<br /><br />
4186 <br /><br />
4189 the full query will be:<br /><br />
4192 <br /><br />
4194 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
4196 spaces inserted there
4197 will be later also inserted as spaces in your query and may lead to unexpected
4198 results especially when
4200 Your initial query which is going to be stored as a bookmark has to yield at
4201 least one result row so
4202 you can store the bookmark. You may have that to work around using well
4206 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4207 include exported table?</a></h4>
4209 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4210 document should look like following one (assuming you have table
4213 <pre>
4214 \documentclass{article} % or any class you want
4215 \usepackage{longtable} % for displaying table
4216 \begin{document} % start of document
4217 \include{table} % including exported table
4218 \end{document} % end of document
4219 </pre>
4223 access them.
4224 </a></h4>
4226 <p> You have one of these global privileges: CREATE
4227 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4228 enable users to see all the database names.
4231 So if your users do not need those privileges, you can remove them and their
4232 databases list will shorten.</p>
4236 possible values for a column, based on some foreign table?</a></h4>
4238 <p> You have to setup appropriate links between the tables, and also
4242 foreign table, a drop-down list of values will be available.
4243 You will see two lists of values, the first list containing the key
4244 and the display column, the second list containing the display column
4245 and the key. The reason for this is to be able to type the first
4246 letter of either the key or the display column.<br /><br />
4248 For 100 values or more, a distinct window will appear, to browse foreign
4249 key values and choose one. To change the default limit of 100, see
4250 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4254 automatically when entering Browse mode for a table?</a></h4>
4256 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
4257 </p>
4261 Excel files, how can I enable that?</a></h4>
4263 <p> You can use
4265 which works out of the box, but phpMyAdmin supports direct export
4266 to Microsoft Excel version 97 and newer. For this to work, you need to set
4271 <pre>
4272 cd phpMyAdmin
4273 mkdir tmp
4274 chmod o+rwx tmp
4275 </pre>
4279 what happens to my column comments stored in pmadb?</a></h4>
4281 <p> Automatic migration of a table's pmadb-style column comments to the native
4282 ones is done whenever you enter Structure page for this table.</p>
4287 <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
4288 <ul>
4291 later)</li>
4294 </ul>
4298 <ol>
4299 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of "localhost".</li>
4300 <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>
4301 <li>When you insert or update a row in this table, put a checkmark on the "Upload to BLOB repository" optional choice; otherwise, the upload will be done directly in your LONGBLOB column instead of the repository.</li>
4302 <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example "View image". A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time.</li>
4303 </ol>
4308 <p> Click the first row of the range, hold the shift key and click the last row of the range. This works everywhere you see rows, for example in Browse mode or on the Structure page.</p>
4314 <p>
4315 In all places where phpMyAdmin accepts format strings, you can use
4318 expanded variables depend on a context (for example, if you haven't chosen a
4319 table, you can not get the table name), but the following variables can be used:
4320 </p>
4321 <dl>
4327 <dd>Verbose MySQL server name as defined in <a href="#cfg_Servers_verbose">server configuration</a></dd>
4338 </dl>
4343 <p>
4344 By clicking on the button 'toggle scratchboard' on the page
4345 where you edit x/y coordinates of those elements you can activate a
4346 scratchboard where all your elements are placed. By clicking on an
4347 element, you can move them around in the pre-defined area and the x/y
4348 coordinates will get updated dynamically. Likewise, when entering a
4349 new position directly into the input field, the new position in the
4350 scratchboard changes after your cursor leaves the input field.
4351 </p>
4352 <p>
4353 You have to click on the 'OK'-button below the tables to save the new
4354 positions. If you want to place a new element, first add it to the
4355 table of elements and then you can drag the new element around.
4356 </p>
4357 <p>
4358 By changing the paper size and the orientation you can change the size
4359 of the scratchboard as well. You can do so by just changing the
4360 dropdown field below, and the scratchboard will resize automatically,
4361 without interfering with the current placement of the elements.
4362 </p>
4363 <p>
4364 If ever an element gets out of range you can either enlarge the paper
4365 size or click on the 'reset' button to place all elements below each
4366 other.
4367 </p>
4372 <p> Not every table can be put to the chart. Only tables with one, two or three columns can be visualised as a chart. Moreover the table must be in a special format for chart script to understand it. Currently supported formats can be found in the <a href="http://wiki.phpmyadmin.net/pma/Charts#Data_formats_for_query_results_chart">wiki</a>.</p>

4390 existing language, where do I start?</a></h4>
4392 <p> Always use latest Git version of the po file to translate. You can optionally
4394 server</a> where you can also get the latest po files and merge them
4395 with your translations. For creating a new translation simply use
4399 to do this) or ask on the mailing list to add the translation to the web
4400 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Gettext_for_translators">our wiki</a>.
4401 </p>
4402 <p>
4403 Please note that we try not to use HTML entities like &eacute; in
4404 the translations, since we define the right character set in the file.
4405 With HTML entities, the text on JavaScript messages would not
4406 display correctly.
4407 However there are some entities that need to be there: quotes,
4408 non-breakable spaces, ampersands, less than, greater than.
4409 </p>
4410 <p>
4411 You can then put your translations, as a zip file to avoid losing special
4412 characters, on the sourceforge.net <a href="https://sourceforge.net/tracker/?group_id=23067&atid=387645">translation tracker.</a>
4413 </p>
4414 <p>
4415 It would be a good idea to subscribe to the <a href="https://lists.sourceforge.net/lists/listinfo/phpmyadmin-translators">phpmyadmin-translators</a> mailing
4416 list, because this is where we ask for translations of new messages.
4417 </p>
4419 <p>
4420 Documentation is being translated using po4a and gettext (see
4422 for existing translations). To start, checkout
4423 <a href="http://phpmyadmin.git.sourceforge.net/git/gitweb.cgi?p=phpmyadmin/localized_docs;a=tree;f=po"><code>localized_docs/po</code></a>
4424 from Git, or just go to the <a href="https://l10n.cihar.com/projects/pmadoc/">translation server</a>
4425 and translate it online. If your language is missing, just contact
4427 you prefer to directly translate the po files, please put updated ones into our

4454 have already contributed something useful to phpMyAdmin.<br />
4460 <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>
4462 <p> Please refer to

4464 </p>
4469 <p> If you use Apache web server, phpMyAdmin exports information about
4470 authentication to the Apache environment and it can be used in Apache logs.
4471 Currently there are two variables available:
4472 </p>
4473 <dl>
4475 <dd>User name of currently active user (he does not have to be logged
4476 in).</dd>
4483 </dl>
4484 <p>
4486 </p>
4487 <pre>
4490 </pre>
4491 <p>
4492 You can then use any log analyzing tools to detect possible break-in
4493 attempts.
4494 </p>
4500 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4501 It allows you to connect to local as well as remote servers. This requires you to enter
4502 server host name, username, password, port and the name of the database. Therefore you can
4503 now synchronize your databases placed on the same server or some remote server.
4504 </p>
4506 <p>
4507 This feature is helpful for developers who need to replicate their
4508 database’s structure as well as data. Moreover, this feature not only
4509 helps replication but also facilitates the user to keep his/her database
4510 in sync with another database. Other than the full database, certain
4511 tables of the databases can also be synchronized.
4512 </p>
4514 <p>
4515 You need to fill in the host name of the server, the username and
4516 password of an user account already there in MySQL. Port is by default
4517 populated with 3306 (MySQL default port). Then the name of the database
4518 should be mentioned at the end. All the information other than the port
4519 needs to be filled explicitly for the source as well as target servers.
4520 </p>
4522 <p>
4523 After successfully passing through the authentication phase, the source and
4524 target database table names will be displayed. It will be a tabular
4525 representation.
4526 </p>
4528 <p>
4529 On the left, are listed the source database table names. Some of the
4531 are only present in source database and they need to be added to the
4532 target database in order to synchronize the target database. The tables
4534 target database.
4535 </p>
4537 <p>
4538 On the right, are listed the target database table names. There are few
4540 means that these tables are to be created in target database in order to
4541 synchronize target database with source database. Some table names
4543 only present in target database and they will remain unchanged in the
4544 target database. The column in the middle shows the difference between
4545 the source and target corresponding tables.
4546 </p>
4548 <p>
4550 letters, indicating that either Structure or Data are not up to date. By
4551 clicking on them, they will turn grey, what means that they will be synchronized.

4933 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4934 to create a web-based interface to MySQL using PHP3. Although I have not
4935 used any of his source-code, there are some concepts I've borrowed from
4936 him. phpMyAdmin was created because Peter told me he wasn't going to
4937 further develop his (great) tool.

4944 code for the check when dropping a table or database. He also suggested
4945 that you should be able to specify the primary key on tbl_create.php3. To
4946 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4947 well as a bug-report. Plus many smaller improvements.
4948 </li>

4952 bug-fixes and help.
4953 </li>
