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.

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

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

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

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

549 supported for cookie authentication mode only). Swekey Authentication is

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

1002 Starting with release 2.5.0, comments are consequently used on the table
1003 property pages and table browse view, showing up as tool-tips above the
1004 column name (properties page) or embedded within the header of table in
1005 browse view. They can also be shown in a table dump. Please see the
1006 relevant configuration directives later on.<br /><br />
1008 Also new in release 2.5.0 is a MIME-transformation system which is also
1010 Transformations</a> for further information. To use the
1011 MIME-transformation system, your column_info table has to have the three
1012 new columns 'mimetype', 'transformation', 'transformation_options'.

1041 all queries you entered manually into the phpMyAdmin interface. If you
1042 don't want to use a table-based history, you can use the JavaScript-based
1043 history. Using that, all your history items are deleted when closing the
1044 window.<br /><br />
1046 Using
1048 you can specify an amount of history items you want to have on hold. On
1049 every login, this list gets cut to the maximum amount.<br /><br />

1067 Since release 3.5.0 you can show recently used tables in the left navigation frame.
1068 It helps you to jump across table directly, without the need to select the database,
1069 and then select the table. Using
1071 you can configure the maximum number of recent tables shown. When you select a table
1072 from the list, it will jump to the page specified in
1073 <a href="#cfg_LeftDefaultTabTable" class="configrule">$cfg['LeftDefaultTabTable']</a>.<br/><br/>
1075 Without configuring the storage, you can still access the recently used tables,

1109 Since release 3.3.x a tracking mechanism is available.
1111 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1112 and data definition statements. After enabling it you can create versions of tables.
1113 <br/><br/>
1114 The creation of a version has two effects:
1116 <ul>
1118 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1119 </ul>
1121 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1122 For the report you can use filters, for example you can get a list of statements within a date range.
1123 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1124 In addition you can export the (filtered) report to a file or to a temporary database.

2170 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2171 or icon is always displayed on the left panel. If JavaScript is enabled in
2172 your browser, a click on this opens a distinct query window, which is
2173 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2174 changes to display a query box.<br /><br />

2187 <br /><br />
2188 The usage of the JavaScript query window is recommended if you have a
2189 JavaScript enabled browser. Basic functions are used to exchange quite
2190 a few variables, so most 4th generation browsers should be capable to

2200 When using the JavaScript based query window, it will always get
2201 updated when you click on a new table/db to browse and will focus if
2202 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2203 the query window by checking the box "Do not overwrite this query from
2204 outside the window" below the query textarea. Then you can browse
2205 tables/databases in the background without losing the contents of the
2206 textarea, so this is especially useful when composing a query with
2207 tables you first have to look in. The checkbox will get automatically
2208 checked whenever you change the contents of the textarea. Please

2402 <!-- TRANSFORMATIONS -->
2408 </ol>
2412 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2414 section</a> on how to do so.</p>
2416 <p> You can apply different transformations to the contents of each column. The
2417 transformation will take the content of each column and transform it with
2418 certain rules defined in the selected transformation.</p>
2420 <p> Say you have a column 'filename' which contains a filename. Normally you would
2421 see in phpMyAdmin only this filename. Using transformations you can transform
2422 that filename into a HTML link, so you can click inside of the phpMyAdmin
2423 structure on the column's link and will see the file displayed in a new browser
2424 window. Using transformation options you can also specify strings to
2425 append/prepend to a string or the format you want the output stored in.</p>
2427 <p> For a general overview of all available transformations and their options,
2428 you can consult your
2429 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2430 installation.</p>
2432 <p> For a tutorial on how to effectively use transformations, see our
2434 the official phpMyAdmin homepage.</p>
2438 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2439 clicking on the 'Structure' link for a table). There click on
2440 "Change" (or change icon) and there you will see three new
2441 fields at
2442 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2443 'Transformation options'.</p>
2445 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2446 that corresponds to the column's contents. Please note that
2447 transformations are inactive as long as no MIME-type is selected.</li>
2449 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2450 hopefully growing amount of pre-defined transformations. See below for information on
2451 how to build your own transformation.<br />
2453 There are global transformations and mimetype-bound transformations. Global transformations
2454 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2455 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2456 transformations which operate on the main mimetype (like 'image'), which will most likely
2457 take the subtype into regard, and those who only operate on a
2458 specific subtype (like 'image/jpeg').<br />
2460 You can use transformations on mimetypes for which the function was not defined for. There
2461 is no security check for you selected the right transformation, so take care of what the
2462 output will be like.</li>
2464 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2465 transform-function specific options here. Usually the transforms can operate with default
2466 options, but it is generally a good idea to look up the overview to see which options are
2467 necessary.<br />
2469 Much like the ENUM/SET-Fields, you have to split up several options using the format
2470 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2471 parsed as an array, leaving the first value the first element in the array, and so
2472 forth.<br />
2474 If you want to specify a MIME character set you can define it in the transformation_options.
2475 You have to put that outside of the pre-defined options of the specific mime-transform,
2477 for which you can specify 2 options and you want to append a character set, enter "'first
2478 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2480 </ul>
2484 <p> All mimetypes and their transformations are defined through single files in
2485 the directory 'libraries/transformations/'.</p>
2487 <p> They are stored in files to ease up customization and easy adding of new
2488 transformations.</p>
2490 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2491 always work. It makes no sense to apply a transformation to a mimetype the
2492 transform-function doesn't know to handle.</p>
2494 <p> One can, however, use empty mime-types and global transformations which should work
2495 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2496 for, but pay attention to option usage as well as what the transformation does to your
2497 column.</p>
2499 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2500 any other transform function and provides some basic functions.</p>
2502 <p> There are 5 possible file names:</p>
2504 <ol><li>A mimetype+subtype transform:<br /><br />
2506 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2508 Please not that mimetype and subtype are separated via '_', which shall
2509 not be contained in their names. The transform function/filename may
2510 contain only characters which cause no problems in the file system as
2511 well as the PHP function naming convention.<br /><br />
2513 The transform function will the be called
2514 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2516 <b>Example:</b><br /><br />
2518 <tt>text_html__formatted.inc.php</tt><br />
2519 <tt>PMA_transform_text_html__formatted()</tt></li>
2521 <li>A mimetype (w/o subtype) transform:<br /><br />
2523 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2525 Please note that there are no single '_' characters.
2526 The transform function/filename may contain only characters which cause
2527 no problems in the file system as well as the PHP function naming
2528 convention.<br /><br />
2530 The transform function will the be called
2531 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2533 <b>Example:</b><br /><br />
2535 <tt>text__formatted.inc.php</tt><br />
2536 <tt>PMA_transform_text__formatted()</tt></li>
2538 <li>A mimetype+subtype without specific transform function<br /><br />
2540 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2542 Please note that there are no '__' characters in the filename. Do not
2543 use special characters in the filename causing problems with the file
2544 system.<br /><br />
2546 No transformation function is defined in the file itself.<br /><br />
2548 <b>Example:</b><br /><br />
2550 <tt>text_plain.inc.php</tt><br />
2551 (No function)</li>
2553 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2555 <tt>[mimetype].inc.php</tt><br /><br />
2557 Please note that there are no '_' characters in the filename. Do not use
2558 special characters in the filename causing problems with the file system.
2559 <br /><br />
2561 No transformation function is defined in the file itself.<br /><br />
2563 <b>Example:</b><br /><br />
2565 <tt>text.inc.php</tt><br />
2566 (No function)</li>
2568 <li>A global transform function with no specific mimetype<br /><br />
2570 <tt>global__[transform].inc.php</tt><br /><br />
2572 The transform function will the be called
2573 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2575 <b>Example:</b><br /><br />
2577 <tt>global__formatted</tt><br />
2578 <tt>PMA_transform_global__formatted()</tt></li>
2579 </ol>
2581 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2582 transform function.</p>
2584 <p> All filenames containing no '__' in themselves are not shown as valid transform
2585 functions in the dropdown.</p>
2587 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2588 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2589 without a transform function.</p>
2591 <p> To create a new transform function please see
2592 <tt>libraries/transformations/template_generator.sh</tt>.
2593 To create a new, empty mimetype please see
2594 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2596 <p> A transform function always gets passed three variables:</p>
2598 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2599 you want to transform.</li>
2600 <li><b>$options</b> - Contains any user-passed options to a transform function
2601 as an array.</li>

2779 </h4>
2781 <p> Starting with version 2.7.0, the import engine has been re–written and these
2782 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2783 to take advantage of the new import features.</p>
2785 <p> The first things to check (or ask your host provider to check) are the
2786 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2787 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2788 All of these three settings limit the maximum size of data that can be
2789 submitted and handled by PHP. One user also said that post_max_size
2790 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2792 There exist several workarounds if your upload is too big or your
2793 hosting provider is unwilling to change the settings:</p>

2806 directly. You can do this by issuing the "source" command from
2807 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2808 </ul>
2812 support?</a></h4>
2814 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2815 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
2816 connect to your MySQL server using PHP's classic

2820 good reason not to do so.<br />
2821 When compiling PHP, we strongly recommend that you manually link the MySQL
2822 extension of your choice to a MySQL client library of at least the same
2823 minor version since the one that is bundled with some PHP distributions is

2865 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2866 "MySQL extension". This extension may be part of the PHP
2867 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2868 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2869 to load the extension but failed.<br /><br />

2894 this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
2895 Just edit your <tt>my.ini</tt> file that should be located in your Windows
2896 directory and add the following line to the group [mysqld]:</p>

2949 <p> This can happen due to a MySQL bug when having database / table names with

2951 To fix this, turn off this directive, convert all database and table names

2959 <p> It is possible to configure Apache in such a way that PHP has problems
2960 interpreting .php files.</p>
2962 <p> The problems occur when two different (and conflicting) set of directives

2976 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2977 The recommended way is with <tt>AddType</tt>, so just comment out
2978 the first set of lines and restart Apache:</p>

3072 <p> If your cluster consist of different architectures, PHP code used for
3073 encryption/decryption won't work correct. This is caused by use of
3074 pack/unpack functions in code. Only solution is to use mcrypt extension
3075 which works fine in this case.</p>
3080 <p> Yes but the default configuration values of Suhosin are known to cause
3081 problems with some operations, for example editing a table with many
3082 columns and no primary key or with textual primary key.
3083 </p>
3084 <p>
3085 Suhosin configuration might lead to malfunction in some cases and it can
3086 not be fully avoided as phpMyAdmin is kind of application which needs to
3087 transfer big amounts of columns in single HTTP request, what is something
3088 what Suhosin tries to prevent. Generally all
3089 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3090 <code>suhosin.get.*</code> directives can have negative effect on
3091 phpMyAdmin usability. You can always find in your error logs which limit
3092 did cause dropping of variable, so you can diagnose the problem and adjust
3093 matching configuration variable.
3094 </p>
3095 <p>
3096 The default values for most Suhosin configuration options will work in most
3097 scenarios, however you might want to adjust at least following parameters:

3125 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>
3127 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />
3128 Example from the Apache 2.2 documentation:</p>
3129 <pre>
3130 ProxyPass /mirror/foo/ http://backend.example.com/
3131 ProxyPassReverse /mirror/foo/ http://backend.example.com/
3132 ProxyPassReverseCookieDomain backend.example.com public.example.com

3134 </pre>
3136 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3137 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
3138 This is not specific to phpmyadmin, it's just the behavior of Apache.

3186 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3188 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3189 In your <i>php.ini</i> you will find a line</p>
3191 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3193 <p> change it to</p>
3195 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3197 <p> Then restart apache and it will work.</p>
3199 <p> Here is a fix suggested by Brad Ummer:</p>
3201 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3202 To do this, telnet to your server and go to the MySQL bin directory. In
3203 this directory there should be a file named <i>mysqladmin</i>. Type
3204 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3205 info about your MySQL server, including the socket
3206 (<i>/tmp/mysql.sock</i>, for example).</li>
3207 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3208 phpMyAdmin, you need to complete the socket information in the
3209 <i>config.inc.php</i>.<br />
3210 For example:
3212 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3213 <br /><br />
3215 Please also make sure that the permissions of this file allow to be readable
3216 by your webserver (i.e. '0755').</li>

3241 directive in the phpMyAdmin configuration file.</p>
3245 password: YES)"-error when trying to access a MySQL-Server on a
3246 host which is port-forwarded for my localhost.</a></h4>
3248 <p> When you are using a port on your localhost, which you redirect via
3249 port-forwarding to another host, MySQL is not resolving the localhost
3250 as expected.<br />
3251 Erik Wasser explains: The solution is: if your host is "localhost"
3252 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3253 connection for speeding up things. And that doesn't work in this configuration
3254 with port forwarding.<br />
3260 <p> Themes are configured with
3264 <br />
3266 should not delete the directory "original" or its underlying
3267 structure, because this is the system theme used by phpMyAdmin.
3268 "original" contains all images and styles, for backwards
3269 compatibility and for all themes that would not include images or css-files.
3270 <br /><br />
3273 is enabled, you can select your favorite theme on the main page. Your
3274 selected theme will be stored in a cookie.<br /><br /></p>
3276 <p> To create a theme:</p>
3278 <ul><li>make a new subdirectory (for example "your_theme_name") under
3280 (by default <tt>themes</tt>)</li>
3281 <li>copy the files and directories from "original" to
3282 "your_theme_name"</li>
3283 <li>edit the css-files in "your_theme_name/css"</li>
3284 <li>put your new images in "your_theme_name/img"</li>
3285 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
3286 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
3287 contain your chosen theme name, that will be visible in user interface</li>
3288 <li>make a new screenshot of your theme and save it under
3289 "your_theme_name/screen.png"</li>
3290 </ul>
3292 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3293 theme verbose name, theme generation and theme version. These versions and
3294 generations are enumerated from 1 and do not have any direct dependence on
3295 phpMyAdmin version. Themes within same generation should be backwards
3296 compatible - theme with version 2 should work in phpMyAdmin requiring
3297 version 1. Themes with different generation are incompatible.</p>
3299 <p> If you do not want to use your own symbols and buttons, remove the
3300 directory "img" in "your_theme_name". phpMyAdmin will
3301 use the default icons and buttons (from the system-theme "original").
3302 </p>
3306 what can I do?</a></h4>
3308 <p> Here are a few points to check:</p>
3310 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3312 directive empty. See also
3314 </li>
3315 <li>Maybe you have a broken PHP installation or you need to upgrade
3316 your Zend Optimizer. See
3318 http://bugs.php.net/bug.php?id=31134</a>.
3319 </li>
3320 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3321 set to the default (200) or another low value, you could get this
3322 error if your table has a high number of columns. Adjust this setting
3323 accordingly. (Thanks to Klaus Dorninger for the hint).
3324 </li>
3325 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3326 of ";" will cause this error. Replace it with "&;".
3327 </li>
3329 you might want to increase
3331 </li>
3332 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3333 </li>
3334 </ul>
3339 <p> To be able to see a progress bar during your uploads, your server must
3342 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3343 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3350 who logged out can not log in again in with the same nick.</a></h4>
3352 <p> This is related to the authentication mechanism (protocol) used by
3353 phpMyAdmin. To bypass this problem: just close all the opened
3354 browser windows and then go back to phpMyAdmin. You should be able to
3355 log in again.</p>
3359 limit error or a time limit error.</a></h4>
3361 <p> Compressed dumps are built in memory and because of this are limited to
3362 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3363 using
3365 (enabled by default). Zip exports can not be handled this way, so if you need
3366 Zip files for larger dump, you have to use another way.</p>
3370 when I rename a table or a column.</a></h4>
3372 <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>
3376 bundled with the MySQL server distribution.</a></h4>
3378 <p> The problem is that older versions of <code>mysqldump</code> created invalid comments like this:</p>
3380 <pre>
3381 -- MySQL dump 8.22
3382 --
3383 -- Host: localhost Database: database
3384 ---------------------------------------------------------
3385 -- Server version 3.23.54
3386 </pre>
3388 <p> The invalid part of the code is the horizontal line made of dashes that
3389 appears once in every dump created with mysqldump. If you want to run your
3390 dump you have to turn it into valid MySQL. This means, you have to add a
3391 whitespace after the first two dashes of the line or add a # before it:
3392 <br />
3393 <code>
3394 -- -------------------------------------------------------<br />
3395 </code>
3396 or<br />
3397 <code>
3398 #---------------------------------------------------------
3399 </code>
3400 </p>
3407 <p> Please note that you should not use the separating string multiple times
3408 without any characters between them, or at the beginning/end of your table
3409 name. If you have to, think about using another TableSeparator or disabling
3410 that feature</p>
3415 <p> In Relation view, being able to choose a table in another database,
3416 or having more than one index column in the foreign key.<br /><br/>
3417 In Query-by-example (Query), automatic generation of the query
3418 LEFT JOIN from the foreign table.<br /><br/>
3419 </p>
3423 I get series of errors like "Warning: unable to parse url". How
3424 can this be fixed?</a></h4>
3425 <p>
3426 Your table neither have a primary key nor an unique one, so we must use a
3427 long expression to identify this row. This causes problems to parse_url
3428 function. The workaround is to create a primary or unique key.
3429 <br />
3430 </p>
3434 a MIME-Transformation onto!</a></h4>
3436 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3437 nested forms can be put inside the table where phpMyAdmin displays the results.
3438 You can, however, use any form inside of a table if keep the parent
3439 form-container with the target to tbl_row_delete.php and just put your own
3440 input-elements inside. If you use a custom submit input field, the form will
3441 submit itself to the displaying page again, where you can validate the
3442 $HTTP_POST_VARS in a transformation.
3444 For a tutorial on how to effectively use transformations, see our
3446 on the official phpMyAdmin-homepage.</p>
3450 MySQL server</a></h4>
3452 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3455 http://dev.mysql.com/doc/mysql/en/ansi-mode.html</a>). Most important of all,
3456 the quote-character (") is interpreted as an identifier quote character and
3457 not as a string quote character, which makes many internal phpMyAdmin
3459 statements. There is no workaround to this behaviour. News to this item will
3460 be posted in Bug report
3461 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>

3466 more that one column with the same value
3467 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3468 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3470 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3471 can use it for the Edit and Delete links.</p>
3476 <p> phpMyAdmin uses a quick method to get the row count, and this method
3477 only returns an approximate count in the case of InnoDB tables. See
3479 a way to modify those results, but
3480 this could have a serious impact on performance.</p>

3497 This has been a known limitation of phpMyAdmin since the beginning and
3498 it's not likely to be solved in the future.

3501 <!-- Begin: Excel import limitations -->
3504 <a href="#faq3_15">3.15 When I import an Excel spreadsheet, some cells with calculations do not display correctly.</a></h4>
3505 <p>
3506 phpMyAdmin uses the <a href="http://www.codeplex.com/PHPExcel/">PHPExcel</a> library to parse Excel XLS and XLSX spreadsheets.
3507 Therefore, any limitations that are listed on their page regarding Excel calculations will also apply here.
3508 <br /><br />
3509 PHPExcel will be kept up to date so as to make all improvements available to phpMyAdmin users.

3513 <a href="#faq3_16">3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import it, nothing happens.</a></h4>
3514 <p>
3515 Since Excel XLSX workbooks are already compressed, there is often times only a small benefit from compressing them yet again.
3516 Support for compressed Excel XLSX and XLS workbooks may be added in the future.
3517 </p>
3520 <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>
3521 <p>
3522 Excel's internal representation of custom cell types is rather muddled (especially in Excel 97-2003 binary XLS files). If possible,
3523 consider using a built-in type. These are almost always guarenteed to import correctly.

3530 <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>
3531 <p>
3532 There is no reliable way to differentiate tables in CSV format. For the time being, you will have to break apart CSV files containing multiple tables.

3540 <p>
3541 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
3542 you will have to edit the structure to your liking post-import.
3543 <br /><br />
3544 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
3545 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.

3987 See also <a href="#faq6_21"><abbr title="Frequently Asked Questions">FAQ</abbr> 6.21</a> for an additional feature that "display column"
3988 enables: drop-down list of possible values.

3992 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3993 <p>
3996 <br /><br />
3997 Then you need to think about your schema layout. Which tables will go on
3998 which pages?
3999 </p>
4000 <ul>
4006 page and click Go. If you like, you
4008 linked tables onto the new page.</li>
4009 <li>Select the name of the new page (making sure the Edit radio button
4010 is selected) and click Go.</li>
4012 Coordinates are relative; your diagram will
4013 be automatically scaled to fit the page. When initially placing tables
4014 on the page, just pick any coordinates -- say, 50x50. After clicking
4016 position the element correctly.</li>
4018 first be sure to click the Save
4019 button beneath the list of tables and coordinates, to save any changes
4020 you made there. Then scroll all the way down, select the
4022 you want, and click Go.</li>
4023 <li>Internet Explorer for Windows may suggest an incorrect filename when
4028 browsers on Windows, do not have this problem.</li>
4029 </ul>
4033 columns!</a></h4>
4035 <p> No, it's MySQL that is doing
4041 underscores in the database name?</a></h4>
4043 <p> If you do not put a backslash before the underscore, this is a wildcard
4046 john2db ...<br /><br />
4048 If you put a backslash before the underscore, it means that the database
4049 name will have a real underscore.</p>
4053 statistics pages?</a></h4>
4064 if it already exists during the import. It does NOT drop the table after
4065 your export, it only affects the import file.</li>
4067 Otherwise, you may get an error if the table name exists but has a
4068 different structure.</li>
4070 (if any) will be included in backup.</li>
4072 column and table names formed with special characters are protected.</li>
4074 types set in the pmadb in the dump as
4076 </li>
4077 </ul>
4082 command, for better documentation (but resulting file is bigger).</li>
4084 once the INSERT verb and the table name.</li>
4087 </li>
4089 more info is provided in the
4091 but basically with this selected, invalid values are adjusted and
4092 inserted rather than causing the entire statement to fail.</li>
4093 </ul>
4097 in its name.</a></h4>
4100 is the normal way to reference a database and table name. Worse, MySQL
4101 will usually let you create a database with a dot, but then you cannot
4102 work with it, nor delete it.</p>
4108 <p>
4109 To use SQL Validator, you need PHP with
4115 module.
4116 </p>
4118 <p>
4124 usage.
4125 </p>
4127 <p>
4128 If you use the Validator, you should be aware that any
4130 submit will be stored anonymously (database/table/column names,
4131 strings, numbers replaced with generic values). The Mimer
4134 We utilize it as free SOAP service.
4135 </p>
4139 it, but MySQL says "BLOB column '...' used in key specification without
4142 <p> The right way to do this, is to create the column without any indexes,
4144 dialog. On this page, you will be able to choose your BLOB column, and
4145 set a size to the index, which is the condition to create an index on
4146 a BLOB column.</p>
4150 editing fields?</a></h4>
4152 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4153 with many editing fields (table structure changes, row editing, etc.).
4154 You can also have a look at the directive
4156 ('vertical') and see if this eases up editing for you.</p>
4160 WTF is this feature then useful for?</a></h4>
4162 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4163 on them. Otherwise you could just put a comment on the column. Because entering
4164 your own mimetype will cause serious syntax checking issues and validation,
4165 this introduces a high-risk false-user-input situation. Instead you have to
4166 initialize mimetypes using functions or empty mimetype definitions.<br />
4167 Plus, you have a whole overview of available mimetypes. Who knows all those
4168 mimetypes by heart so he/she can enter it at will?</p>
4172 can't I see any bookmarks below the query box? What is this variable for?
4173 </a></h4>
4175 <p> Any query you have executed can be stored as a bookmark on the page where the
4176 results are displayed. You will find a button labeled 'Bookmark this query'
4177 just at the end of the page.<br />
4178 As soon as you have stored a bookmark, it is related to the database you run
4179 the query on. You can now access a bookmark dropdown on each page, the query
4180 box appears on for that database.<br /><br />
4182 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4186 aware of that you HAVE to create a valid query, otherwise your query won't be
4187 even able to be stored in the database.<br />
4189 for your query will remain the way it is, but will be stripped of the /**/
4190 chars. So you can use:<br /><br />
4194 which will be expanded to<br /><br />
4198 in your query, where VARIABLE is the string you entered in the input box. If
4199 an empty string is provided, no replacements are made.<br /><br />
4201 A more complex example. Say you have stored this query:<br /><br />
4203 <br /><br />
4206 the full query will be:<br /><br />
4209 <br /><br />
4211 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
4213 spaces inserted there
4214 will be later also inserted as spaces in your query and may lead to unexpected
4215 results especially when
4217 Your initial query which is going to be stored as a bookmark has to yield at
4218 least one result row so
4219 you can store the bookmark. You may have that to work around using well
4223 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4224 include exported table?</a></h4>
4226 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4227 document should look like following one (assuming you have table
4230 <pre>
4231 \documentclass{article} % or any class you want
4232 \usepackage{longtable} % for displaying table
4233 \begin{document} % start of document
4234 \include{table} % including exported table
4235 \end{document} % end of document
4236 </pre>
4240 access them.
4241 </a></h4>
4243 <p> You have one of these global privileges: CREATE
4244 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4245 enable users to see all the database names.
4248 So if your users do not need those privileges, you can remove them and their
4249 databases list will shorten.</p>
4253 possible values for a column, based on some foreign table?</a></h4>
4255 <p> You have to setup appropriate links between the tables, and also
4259 foreign table, a drop-down list of values will be available.
4260 You will see two lists of values, the first list containing the key
4261 and the display column, the second list containing the display column
4262 and the key. The reason for this is to be able to type the first
4263 letter of either the key or the display column.<br /><br />
4265 For 100 values or more, a distinct window will appear, to browse foreign
4266 key values and choose one. To change the default limit of 100, see
4267 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4271 automatically when entering Browse mode for a table?</a></h4>
4273 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
4274 </p>
4278 Excel files, how can I enable that?</a></h4>
4280 <p> You can use
4282 which works out of the box, but phpMyAdmin supports direct export
4283 to Microsoft Excel version 97 and newer. For this to work, you need to set
4288 <pre>
4289 cd phpMyAdmin
4290 mkdir tmp
4291 chmod o+rwx tmp
4292 </pre>
4296 what happens to my column comments stored in pmadb?</a></h4>
4298 <p> Automatic migration of a table's pmadb-style column comments to the native
4299 ones is done whenever you enter Structure page for this table.</p>
4304 <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
4305 <ul>
4308 later)</li>
4311 </ul>
4315 <ol>
4316 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of "localhost".</li>
4317 <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>
4318 <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>
4319 <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>
4320 </ol>
4325 <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>
4331 <p>
4332 In all places where phpMyAdmin accepts format strings, you can use
4335 expanded variables depend on a context (for example, if you haven't chosen a
4336 table, you can not get the table name), but the following variables can be used:
4337 </p>
4338 <dl>
4344 <dd>Verbose MySQL server name as defined in <a href="#cfg_Servers_verbose">server configuration</a></dd>
4355 </dl>
4360 <p>
4361 By clicking on the button 'toggle scratchboard' on the page
4362 where you edit x/y coordinates of those elements you can activate a
4363 scratchboard where all your elements are placed. By clicking on an
4364 element, you can move them around in the pre-defined area and the x/y
4365 coordinates will get updated dynamically. Likewise, when entering a
4366 new position directly into the input field, the new position in the
4367 scratchboard changes after your cursor leaves the input field.
4368 </p>
4369 <p>
4370 You have to click on the 'OK'-button below the tables to save the new
4371 positions. If you want to place a new element, first add it to the
4372 table of elements and then you can drag the new element around.
4373 </p>
4374 <p>
4375 By changing the paper size and the orientation you can change the size
4376 of the scratchboard as well. You can do so by just changing the
4377 dropdown field below, and the scratchboard will resize automatically,
4378 without interfering with the current placement of the elements.
4379 </p>
4380 <p>
4381 If ever an element gets out of range you can either enlarge the paper
4382 size or click on the 'reset' button to place all elements below each
4383 other.
4384 </p>
4389 <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>

4407 existing language, where do I start?</a></h4>
4409 <p> Always use latest Git version of the po file to translate. You can optionally
4411 server</a> where you can also get the latest po files and merge them
4412 with your translations. For creating a new translation simply use
4416 to do this) or ask on the mailing list to add the translation to the web
4417 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Gettext_for_translators">our wiki</a>.
4418 </p>
4419 <p>
4420 Please note that we try not to use HTML entities like &eacute; in
4421 the translations, since we define the right character set in the file.
4422 With HTML entities, the text on JavaScript messages would not
4423 display correctly.
4424 However there are some entities that need to be there: quotes,
4425 non-breakable spaces, ampersands, less than, greater than.
4426 </p>
4427 <p>
4428 You can then put your translations, as a zip file to avoid losing special
4429 characters, on the sourceforge.net <a href="https://sourceforge.net/tracker/?group_id=23067&atid=387645">translation tracker.</a>
4430 </p>
4431 <p>
4432 It would be a good idea to subscribe to the <a href="https://lists.sourceforge.net/lists/listinfo/phpmyadmin-translators">phpmyadmin-translators</a> mailing
4433 list, because this is where we ask for translations of new messages.
4434 </p>
4436 <p>
4437 Documentation is being translated using po4a and gettext (see
4439 for existing translations). To start, checkout
4440 <a href="http://phpmyadmin.git.sourceforge.net/git/gitweb.cgi?p=phpmyadmin/localized_docs;a=tree;f=po"><code>localized_docs/po</code></a>
4441 from Git, or just go to the <a href="https://l10n.cihar.com/projects/pmadoc/">translation server</a>
4442 and translate it online. If your language is missing, just contact
4444 you prefer to directly translate the po files, please put updated ones into our

4468 <p>More details on git are available on <a href="http://wiki.phpmyadmin.net/pma/Git">our wiki</a>.</p>
4470 <p> Write access to the repository is granted only to experienced developers who
4471 have already contributed something useful to phpMyAdmin.<br />
4477 <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>
4479 <p> Please refer to
4480 <a href="http://www.phpmyadmin.net/home_page/security.php">http://www.phpmyadmin.net/home_page/security.php</a>
4481 </p>
4486 <p> If you use Apache web server, phpMyAdmin exports information about
4487 authentication to the Apache environment and it can be used in Apache logs.
4488 Currently there are two variables available:
4489 </p>
4490 <dl>
4492 <dd>User name of currently active user (he does not have to be logged
4493 in).</dd>
4500 </dl>
4501 <p>
4503 </p>
4504 <pre>
4507 </pre>
4508 <p>
4509 You can then use any log analyzing tools to detect possible break-in
4510 attempts.
4511 </p>
4517 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4518 It allows you to connect to local as well as remote servers. This requires you to enter
4519 server host name, username, password, port and the name of the database. Therefore you can
4520 now synchronize your databases placed on the same server or some remote server.
4521 </p>
4523 <p>
4524 This feature is helpful for developers who need to replicate their
4525 database’s structure as well as data. Moreover, this feature not only
4526 helps replication but also facilitates the user to keep his/her database
4527 in sync with another database. Other than the full database, certain
4528 tables of the databases can also be synchronized.
4529 </p>
4531 <p>
4532 You need to fill in the host name of the server, the username and
4533 password of an user account already there in MySQL. Port is by default
4534 populated with 3306 (MySQL default port). Then the name of the database
4535 should be mentioned at the end. All the information other than the port
4536 needs to be filled explicitly for the source as well as target servers.
4537 </p>
4539 <p>
4540 After successfully passing through the authentication phase, the source and
4541 target database table names will be displayed. It will be a tabular
4542 representation.
4543 </p>
4545 <p>
4546 On the left, are listed the source database table names. Some of the
4548 are only present in source database and they need to be added to the
4549 target database in order to synchronize the target database. The tables
4551 target database.
4552 </p>
4554 <p>
4555 On the right, are listed the target database table names. There are few
4557 means that these tables are to be created in target database in order to
4558 synchronize target database with source database. Some table names
4560 only present in target database and they will remain unchanged in the
4561 target database. The column in the middle shows the difference between
4562 the source and target corresponding tables.
4563 </p>
4565 <p>
4567 letters, indicating that either Structure or Data are not up to date. By
4568 clicking on them, they will turn grey, what means that they will be synchronized.

4950 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4951 to create a web-based interface to MySQL using PHP3. Although I have not
4952 used any of his source-code, there are some concepts I've borrowed from
4953 him. phpMyAdmin was created because Peter told me he wasn't going to
4954 further develop his (great) tool.
