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/>

1084 Since release 3.3.x a tracking mechanism is available.
1086 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1087 and data definition statements. After enabling it you can create versions of tables.
1088 <br/><br/>
1089 The creation of a version has two effects:
1091 <ul>
1093 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1094 </ul>
1096 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1097 For the report you can use filters, for example you can get a list of statements within a date range.
1098 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1099 In addition you can export the (filtered) report to a file or to a temporary database.

1942 Explorer.If set to 'fake' PHP does the transformation for you, but of
1943 course this does not look as good as CSS. The 'auto' option enables

2115 or icon is always displayed on the left panel. If JavaScript is enabled in
2116 your browser, a click on this opens a distinct query window, which is
2117 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2118 changes to display a query box.<br /><br />

2132 The usage of the JavaScript query window is recommended if you have a

2145 updated when you click on a new table/db to browse and will focus if
2146 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2147 the query window by checking the box "Do not overwrite this query from
2148 outside the window" below the query textarea. Then you can browse
2149 tables/databases in the background without losing the contents of the

2363 <!-- TRANSFORMATIONS -->
2369 </ol>
2373 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2375 section</a> on how to do so.</p>
2377 <p> You can apply different transformations to the contents of each column. The
2378 transformation will take the content of each column and transform it with
2379 certain rules defined in the selected transformation.</p>
2381 <p> Say you have a column 'filename' which contains a filename. Normally you would
2382 see in phpMyAdmin only this filename. Using transformations you can transform
2383 that filename into a HTML link, so you can click inside of the phpMyAdmin
2384 structure on the column's link and will see the file displayed in a new browser
2385 window. Using transformation options you can also specify strings to
2386 append/prepend to a string or the format you want the output stored in.</p>
2388 <p> For a general overview of all available transformations and their options,
2389 you can consult your
2390 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2391 installation.</p>
2393 <p> For a tutorial on how to effectively use transformations, see our
2395 the official phpMyAdmin homepage.</p>
2399 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2400 clicking on the 'Structure' link for a table). There click on
2401 "Change" (or change icon) and there you will see three new
2402 fields at
2403 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2404 'Transformation options'.</p>
2406 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2407 that corresponds to the column's contents. Please note that
2408 transformations are inactive as long as no MIME-type is selected.</li>
2410 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2411 hopefully growing amount of pre-defined transformations. See below for information on
2412 how to build your own transformation.<br />
2414 There are global transformations and mimetype-bound transformations. Global transformations
2415 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2416 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2417 transformations which operate on the main mimetype (like 'image'), which will most likely
2418 take the subtype into regard, and those who only operate on a
2419 specific subtype (like 'image/jpeg').<br />
2421 You can use transformations on mimetypes for which the function was not defined for. There
2422 is no security check for you selected the right transformation, so take care of what the
2423 output will be like.</li>
2425 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2426 transform-function specific options here. Usually the transforms can operate with default
2427 options, but it is generally a good idea to look up the overview to see which options are
2428 necessary.<br />
2430 Much like the ENUM/SET-Fields, you have to split up several options using the format
2431 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2432 parsed as an array, leaving the first value the first element in the array, and so
2433 forth.<br />
2435 If you want to specify a MIME character set you can define it in the transformation_options.
2436 You have to put that outside of the pre-defined options of the specific mime-transform,
2438 for which you can specify 2 options and you want to append a character set, enter "'first
2439 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2441 </ul>
2445 <p> All mimetypes and their transformations are defined through single files in
2446 the directory 'libraries/transformations/'.</p>
2448 <p> They are stored in files to ease up customization and easy adding of new
2449 transformations.</p>
2451 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2452 always work. It makes no sense to apply a transformation to a mimetype the
2453 transform-function doesn't know to handle.</p>
2455 <p> One can, however, use empty mime-types and global transformations which should work
2456 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2457 for, but pay attention to option usage as well as what the transformation does to your
2458 column.</p>
2460 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2461 any other transform function and provides some basic functions.</p>
2463 <p> There are 5 possible file names:</p>
2465 <ol><li>A mimetype+subtype transform:<br /><br />
2467 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2469 Please not that mimetype and subtype are separated via '_', which shall
2470 not be contained in their names. The transform function/filename may
2471 contain only characters which cause no problems in the file system as
2472 well as the PHP function naming convention.<br /><br />
2474 The transform function will the be called
2475 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2477 <b>Example:</b><br /><br />
2479 <tt>text_html__formatted.inc.php</tt><br />
2480 <tt>PMA_transform_text_html__formatted()</tt></li>
2482 <li>A mimetype (w/o subtype) transform:<br /><br />
2484 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2486 Please note that there are no single '_' characters.
2487 The transform function/filename may contain only characters which cause
2488 no problems in the file system as well as the PHP function naming
2489 convention.<br /><br />
2491 The transform function will the be called
2492 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2494 <b>Example:</b><br /><br />
2496 <tt>text__formatted.inc.php</tt><br />
2497 <tt>PMA_transform_text__formatted()</tt></li>
2499 <li>A mimetype+subtype without specific transform function<br /><br />
2501 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2503 Please note that there are no '__' characters in the filename. Do not
2504 use special characters in the filename causing problems with the file
2505 system.<br /><br />
2507 No transformation function is defined in the file itself.<br /><br />
2509 <b>Example:</b><br /><br />
2511 <tt>text_plain.inc.php</tt><br />
2512 (No function)</li>
2514 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2516 <tt>[mimetype].inc.php</tt><br /><br />
2518 Please note that there are no '_' characters in the filename. Do not use
2519 special characters in the filename causing problems with the file system.
2520 <br /><br />
2522 No transformation function is defined in the file itself.<br /><br />
2524 <b>Example:</b><br /><br />
2526 <tt>text.inc.php</tt><br />
2527 (No function)</li>
2529 <li>A global transform function with no specific mimetype<br /><br />
2531 <tt>global__[transform].inc.php</tt><br /><br />
2533 The transform function will the be called
2534 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2536 <b>Example:</b><br /><br />
2538 <tt>global__formatted</tt><br />
2539 <tt>PMA_transform_global__formatted()</tt></li>
2540 </ol>
2542 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2543 transform function.</p>
2545 <p> All filenames containing no '__' in themselves are not shown as valid transform
2546 functions in the dropdown.</p>
2548 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2549 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2550 without a transform function.</p>
2552 <p> To create a new transform function please see
2553 <tt>libraries/transformations/template_generator.sh</tt>.
2554 To create a new, empty mimetype please see
2555 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2557 <p> A transform function always gets passed three variables:</p>
2559 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2560 you want to transform.</li>
2561 <li><b>$options</b> - Contains any user-passed options to a transform function
2562 as an array.</li>
2563 <li><b>$meta</b> - Contains an object with information about your column.
2564 The data is drawn from the output of the
2566 function. This means, all object properties described on the
2568 available in this variable and can be used to transform a column accordingly
2569 to unsigned/zerofill/not_null/... properties.<br />
2570 The $meta->mimetype variable contains the original MIME-type of the
2571 column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2572 </ol>
2574 <p> Additionally you should also provide additional function to provide
2575 information about the transformation to the user. This function should
2576 have same name as transformation function just with appended
2577 <code>_info</code> suffix. This function accepts no parameters and returns
2578 array with information about the transformation. Currently following keys
2579 can be used:
2580 </p>
2581 <dl>
2582 <dt><code>info</code></dt>
2583 <dd>Long description of the transformation.</dd>

2677 <p> Your uploaded file is saved by PHP in the "upload dir", as

2679 the system default is <i>/tmp</i>).<br />
2680 We recommend the following setup for Apache servers running in safe mode,
2681 to enable uploads of files while being reasonably secure:</p>
2683 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2684 <li>give ownership to the Apache server's user.group:

2740 </h4>
2742 <p> Starting with version 2.7.0, the import engine has been re–written and these
2743 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2744 to take advantage of the new import features.</p>
2746 <p> The first things to check (or ask your host provider to check) are the
2747 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2748 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2749 All of these three settings limit the maximum size of data that can be
2750 submitted and handled by PHP. One user also said that post_max_size
2751 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2753 There exist several workarounds if your upload is too big or your
2754 hosting provider is unwilling to change the settings:</p>

2766 <li>If you have shell (command line) access, use MySQL to import the files
2767 directly. You can do this by issuing the "source" command from
2768 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2769 </ul>
2773 support?</a></h4>
2775 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2776 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
2777 connect to your MySQL server using PHP's classic

2781 good reason not to do so.<br />

2783 extension of your choice to a MySQL client library of at least the same
2784 minor version since the one that is bundled with some PHP distributions is

2826 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2827 "MySQL extension". This extension may be part of the PHP
2828 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2829 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2830 to load the extension but failed.<br /><br />

2910 <p> This can happen due to a MySQL bug when having database / table names with

2912 To fix this, turn off this directive, convert all database and table names
2913 to lower case and turn it on again. Alternatively, there's a bug-fix

2920 <p> It is possible to configure Apache in such a way that PHP has problems
2921 interpreting .php files.</p>
2923 <p> The problems occur when two different (and conflicting) set of directives

2937 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2938 The recommended way is with <tt>AddType</tt>, so just comment out
2939 the first set of lines and restart Apache:</p>

3031 password encryption in cookie auth doesn't work.</a></h4>
3033 <p> If your cluster consist of different architectures, PHP code used for

3035 pack/unpack functions in code. Only solution is to use mcrypt extension
3036 which works fine in this case.</p>
3041 <p> Yes but the default configuration values of Suhosin are known to cause
3042 problems with some operations, for example editing a table with many
3043 columns and no primary key or with textual primary key.
3044 </p>
3045 <p>
3046 Suhosin configuration might lead to malfunction in some cases and it can
3047 not be fully avoided as phpMyAdmin is kind of application which needs to
3048 transfer big amounts of columns in single HTTP request, what is something
3049 what Suhosin tries to prevent. Generally all
3050 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3051 <code>suhosin.get.*</code> directives can have negative effect on
3052 phpMyAdmin usability. You can always find in your error logs which limit
3053 did cause dropping of variable, so you can diagnose the problem and adjust
3054 matching configuration variable.
3055 </p>
3056 <p>
3057 The default values for most Suhosin configuration options will work in most
3058 scenarios, however you might want to adjust at least following parameters:

3086 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>
3088 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />
3089 Example from the Apache 2.2 documentation:</p>

3091 ProxyPass /mirror/foo/ http://backend.example.com/
3092 ProxyPassReverse /mirror/foo/ http://backend.example.com/
3093 ProxyPassReverseCookieDomain backend.example.com public.example.com

3097 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3098 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
3099 This is not specific to phpmyadmin, it's just the behavior of Apache.

3140 into PHP.</p>
3144 connect to local MySQL server through socket '/tmp/mysql.sock'
3145 (111) ..." is displayed. What can I do?</a></h4>
3147 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3149 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3150 In your <i>php.ini</i> you will find a line</p>
3152 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3154 <p> change it to</p>
3156 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3158 <p> Then restart apache and it will work.</p>
3160 <p> Here is a fix suggested by Brad Ummer:</p>
3162 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3163 To do this, telnet to your server and go to the MySQL bin directory. In
3164 this directory there should be a file named <i>mysqladmin</i>. Type
3165 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3166 info about your MySQL server, including the socket
3167 (<i>/tmp/mysql.sock</i>, for example).</li>
3168 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3169 phpMyAdmin, you need to complete the socket information in the
3170 <i>config.inc.php</i>.<br />
3171 For example:
3173 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3174 <br /><br />
3176 Please also make sure that the permissions of this file allow to be readable
3177 by your webserver (i.e. '0755').</li>

3209 <p> When you are using a port on your localhost, which you redirect via
3210 port-forwarding to another host, MySQL is not resolving the localhost
3211 as expected.<br />
3212 Erik Wasser explains: The solution is: if your host is "localhost"
3213 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3214 connection for speeding up things. And that doesn't work in this configuration
3215 with port forwarding.<br />

3244 <li>edit the css-files in "your_theme_name/css"</li>
3245 <li>put your new images in "your_theme_name/img"</li>
3246 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
3247 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
3248 contain your chosen theme name, that will be visible in user interface</li>
3249 <li>make a new screenshot of your theme and save it under
3250 "your_theme_name/screen.png"</li>
3251 </ul>
3253 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3254 theme verbose name, theme generation and theme version. These versions and
3255 generations are enumerated from 1 and do not have any direct dependence on
3256 phpMyAdmin version. Themes within same generation should be backwards
3257 compatible - theme with version 2 should work in phpMyAdmin requiring
3258 version 1. Themes with different generation are incompatible.</p>
3260 <p> If you do not want to use your own symbols and buttons, remove the
3261 directory "img" in "your_theme_name". phpMyAdmin will
3262 use the default icons and buttons (from the system-theme "original").
3263 </p>
3267 what can I do?</a></h4>
3269 <p> Here are a few points to check:</p>
3271 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3273 directive empty. See also
3275 </li>
3276 <li>Maybe you have a broken PHP installation or you need to upgrade
3277 your Zend Optimizer. See
3279 http://bugs.php.net/bug.php?id=31134</a>.
3280 </li>
3281 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3282 set to the default (200) or another low value, you could get this
3283 error if your table has a high number of columns. Adjust this setting
3284 accordingly. (Thanks to Klaus Dorninger for the hint).
3285 </li>
3286 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3287 of ";" will cause this error. Replace it with "&;".
3288 </li>
3290 you might want to increase
3292 </li>
3293 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3294 </li>
3295 </ul>
3300 <p> To be able to see a progress bar during your uploads, your server must
3303 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3304 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3311 who logged out can not log in again in with the same nick.</a></h4>
3313 <p> This is related to the authentication mechanism (protocol) used by
3314 phpMyAdmin. To bypass this problem: just close all the opened
3315 browser windows and then go back to phpMyAdmin. You should be able to
3316 log in again.</p>
3320 limit error or a time limit error.</a></h4>
3322 <p> Compressed dumps are built in memory and because of this are limited to
3323 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3324 using
3326 (enabled by default). Zip exports can not be handled this way, so if you need
3327 Zip files for larger dump, you have to use another way.</p>
3331 when I rename a table or a column.</a></h4>
3333 <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>
3337 bundled with the MySQL server distribution.</a></h4>
3339 <p> The problem is that older versions of <code>mysqldump</code> created invalid comments like this:</p>
3341 <pre>
3342 -- MySQL dump 8.22
3343 --
3344 -- Host: localhost Database: database
3345 ---------------------------------------------------------
3346 -- Server version 3.23.54
3347 </pre>
3349 <p> The invalid part of the code is the horizontal line made of dashes that
3350 appears once in every dump created with mysqldump. If you want to run your
3351 dump you have to turn it into valid MySQL. This means, you have to add a
3352 whitespace after the first two dashes of the line or add a # before it:
3353 <br />
3354 <code>
3355 -- -------------------------------------------------------<br />
3356 </code>
3357 or<br />
3358 <code>
3359 #---------------------------------------------------------
3360 </code>
3361 </p>
3368 <p> Please note that you should not use the separating string multiple times
3369 without any characters between them, or at the beginning/end of your table
3370 name. If you have to, think about using another TableSeparator or disabling
3371 that feature</p>
3376 <p> In Relation view, being able to choose a table in another database,
3377 or having more than one index column in the foreign key.<br /><br/>

3379 LEFT JOIN from the foreign table.<br /><br/>
3380 </p>
3384 I get series of errors like "Warning: unable to parse url". How
3385 can this be fixed?</a></h4>
3386 <p>
3387 Your table neither have a primary key nor an unique one, so we must use a
3388 long expression to identify this row. This causes problems to parse_url
3389 function. The workaround is to create a primary or unique key.
3390 <br />
3391 </p>
3395 a MIME-Transformation onto!</a></h4>
3397 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3398 nested forms can be put inside the table where phpMyAdmin displays the results.
3399 You can, however, use any form inside of a table if keep the parent
3400 form-container with the target to tbl_row_delete.php and just put your own
3401 input-elements inside. If you use a custom submit input field, the form will
3402 submit itself to the displaying page again, where you can validate the
3403 $HTTP_POST_VARS in a transformation.
3405 For a tutorial on how to effectively use transformations, see our
3407 on the official phpMyAdmin-homepage.</p>
3411 MySQL server</a></h4>
3413 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3416 http://dev.mysql.com/doc/mysql/en/ansi-mode.html</a>). Most important of all,
3417 the quote-character (") is interpreted as an identifier quote character and
3418 not as a string quote character, which makes many internal phpMyAdmin
3420 statements. There is no workaround to this behaviour. News to this item will
3421 be posted in Bug report
3422 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>

3428 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3429 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3431 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3432 can use it for the Edit and Delete links.</p>
3437 <p> phpMyAdmin uses a quick method to get the row count, and this method
3438 only returns an approximate count in the case of InnoDB tables. See
3440 a way to modify those results, but
3441 this could have a serious impact on performance.</p>

3458 This has been a known limitation of phpMyAdmin since the beginning and
3459 it's not likely to be solved in the future.

3462 <!-- Begin: Excel import limitations -->
3465 <a href="#faq3_15">3.15 When I import an Excel spreadsheet, some cells with calculations do not display correctly.</a></h4>
3466 <p>
3467 phpMyAdmin uses the <a href="http://www.codeplex.com/PHPExcel/">PHPExcel</a> library to parse Excel XLS and XLSX spreadsheets.
3468 Therefore, any limitations that are listed on their page regarding Excel calculations will also apply here.
3469 <br /><br />
3470 PHPExcel will be kept up to date so as to make all improvements available to phpMyAdmin users.

3474 <a href="#faq3_16">3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import it, nothing happens.</a></h4>
3475 <p>
3476 Since Excel XLSX workbooks are already compressed, there is often times only a small benefit from compressing them yet again.
3477 Support for compressed Excel XLSX and XLS workbooks may be added in the future.
3478 </p>
3481 <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>
3482 <p>
3483 Excel's internal representation of custom cell types is rather muddled (especially in Excel 97-2003 binary XLS files). If possible,
3484 consider using a built-in type. These are almost always guarenteed to import correctly.

3491 <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>
3492 <p>
3493 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.

3500 <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>
3501 <p>
3502 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
3503 you will have to edit the structure to your liking post-import.
3504 <br /><br />
3505 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
3506 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 on the page, just pick any coordinates -- say, 50x50. After clicking
3977 position the element correctly.</li>
3979 first be sure to click the Save
3980 button beneath the list of tables and coordinates, to save any changes
3981 you made there. Then scroll all the way down, select the
3983 you want, and click Go.</li>
3984 <li>Internet Explorer for Windows may suggest an incorrect filename when
3989 browsers on Windows, do not have this problem.</li>
3990 </ul>
3994 columns!</a></h4>
3996 <p> No, it's MySQL that is doing
4002 underscores in the database name?</a></h4>
4004 <p> If you do not put a backslash before the underscore, this is a wildcard
4007 john2db ...<br /><br />
4009 If you put a backslash before the underscore, it means that the database
4010 name will have a real underscore.</p>
4014 statistics pages?</a></h4>
4025 if it already exists during the import. It does NOT drop the table after
4026 your export, it only affects the import file.</li>
4028 Otherwise, you may get an error if the table name exists but has a
4029 different structure.</li>
4031 (if any) will be included in backup.</li>
4033 column and table names formed with special characters are protected.</li>
4035 types set in the pmadb in the dump as
4037 </li>
4038 </ul>
4043 command, for better documentation (but resulting file is bigger).</li>
4045 once the INSERT verb and the table name.</li>
4048 </li>
4050 more info is provided in the
4052 but basically with this selected, invalid values are adjusted and
4053 inserted rather than causing the entire statement to fail.</li>
4054 </ul>
4058 in its name.</a></h4>
4061 is the normal way to reference a database and table name. Worse, MySQL
4062 will usually let you create a database with a dot, but then you cannot
4063 work with it, nor delete it.</p>
4069 <p>
4070 To use SQL Validator, you need PHP with
4076 module.
4077 </p>
4079 <p>
4085 usage.
4086 </p>
4088 <p>
4089 If you use the Validator, you should be aware that any
4091 submit will be stored anonymously (database/table/column names,
4092 strings, numbers replaced with generic values). The Mimer
4095 We utilize it as free SOAP service.
4096 </p>
4100 it, but MySQL says "BLOB column '...' used in key specification without
4103 <p> The right way to do this, is to create the column without any indexes,
4105 dialog. On this page, you will be able to choose your BLOB column, and
4106 set a size to the index, which is the condition to create an index on
4107 a BLOB column.</p>
4111 editing fields?</a></h4>
4113 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4114 with many editing fields (table structure changes, row editing, etc.).
4115 You can also have a look at the directive
4117 ('vertical') and see if this eases up editing for you.</p>
4121 WTF is this feature then useful for?</a></h4>
4123 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4124 on them. Otherwise you could just put a comment on the column. Because entering
4125 your own mimetype will cause serious syntax checking issues and validation,
4126 this introduces a high-risk false-user-input situation. Instead you have to
4127 initialize mimetypes using functions or empty mimetype definitions.<br />
4128 Plus, you have a whole overview of available mimetypes. Who knows all those
4129 mimetypes by heart so he/she can enter it at will?</p>
4133 can't I see any bookmarks below the query box? What is this variable for?
4134 </a></h4>
4136 <p> Any query you have executed can be stored as a bookmark on the page where the
4137 results are displayed. You will find a button labeled 'Bookmark this query'
4138 just at the end of the page.<br />
4139 As soon as you have stored a bookmark, it is related to the database you run
4140 the query on. You can now access a bookmark dropdown on each page, the query
4141 box appears on for that database.<br /><br />
4143 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4147 aware of that you HAVE to create a valid query, otherwise your query won't be
4148 even able to be stored in the database.<br />
4150 for your query will remain the way it is, but will be stripped of the /**/
4151 chars. So you can use:<br /><br />
4155 which will be expanded to<br /><br />
4159 in your query, where VARIABLE is the string you entered in the input box. If
4160 an empty string is provided, no replacements are made.<br /><br />
4162 A more complex example. Say you have stored this query:<br /><br />
4164 <br /><br />
4167 the full query will be:<br /><br />
4170 <br /><br />
4172 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
4174 spaces inserted there
4175 will be later also inserted as spaces in your query and may lead to unexpected
4176 results especially when
4178 Your initial query which is going to be stored as a bookmark has to yield at
4179 least one result row so
4180 you can store the bookmark. You may have that to work around using well
4184 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4185 include exported table?</a></h4>
4187 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4188 document should look like following one (assuming you have table
4191 <pre>
4192 \documentclass{article} % or any class you want
4193 \usepackage{longtable} % for displaying table
4194 \begin{document} % start of document
4195 \include{table} % including exported table
4196 \end{document} % end of document
4197 </pre>
4201 access them.
4202 </a></h4>
4204 <p> You have one of these global privileges: CREATE
4205 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4206 enable users to see all the database names.
4209 So if your users do not need those privileges, you can remove them and their
4210 databases list will shorten.</p>
4214 possible values for a column, based on some foreign table?</a></h4>
4216 <p> You have to setup appropriate links between the tables, and also
4220 foreign table, a drop-down list of values will be available.
4221 You will see two lists of values, the first list containing the key
4222 and the display column, the second list containing the display column
4223 and the key. The reason for this is to be able to type the first
4224 letter of either the key or the display column.<br /><br />
4226 For 100 values or more, a distinct window will appear, to browse foreign
4227 key values and choose one. To change the default limit of 100, see
4228 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4232 automatically when entering Browse mode for a table?</a></h4>
4234 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
4235 </p>
4239 Excel files, how can I enable that?</a></h4>
4241 <p> You can use
4243 which works out of the box, but phpMyAdmin supports direct export
4244 to Microsoft Excel version 97 and newer. For this to work, you need to set
4249 <pre>
4250 cd phpMyAdmin
4251 mkdir tmp
4252 chmod o+rwx tmp
4253 </pre>
4257 what happens to my column comments stored in pmadb?</a></h4>
4259 <p> Automatic migration of a table's pmadb-style column comments to the native
4260 ones is done whenever you enter Structure page for this table.</p>
4265 <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
4266 <ul>
4269 later)</li>
4272 </ul>
4276 <ol>
4277 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of "localhost".</li>
4278 <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>
4279 <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>
4280 <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>
4281 </ol>
4286 <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>
4292 <p>
4293 In all places where phpMyAdmin accepts format strings, you can use
4296 expanded variables depend on a context (for example, if you haven't chosen a
4297 table, you can not get the table name), but the following variables can be used:
4298 </p>
4299 <dl>
4305 <dd>Verbose MySQL server name as defined in <a href="#cfg_Servers_verbose">server configuration</a></dd>
4316 </dl>
4321 <p>
4322 By clicking on the button 'toggle scratchboard' on the page
4323 where you edit x/y coordinates of those elements you can activate a
4324 scratchboard where all your elements are placed. By clicking on an
4325 element, you can move them around in the pre-defined area and the x/y
4326 coordinates will get updated dynamically. Likewise, when entering a
4327 new position directly into the input field, the new position in the
4328 scratchboard changes after your cursor leaves the input field.
4329 </p>
4330 <p>
4331 You have to click on the 'OK'-button below the tables to save the new
4332 positions. If you want to place a new element, first add it to the
4333 table of elements and then you can drag the new element around.
4334 </p>
4335 <p>
4336 By changing the paper size and the orientation you can change the size
4337 of the scratchboard as well. You can do so by just changing the
4338 dropdown field below, and the scratchboard will resize automatically,
4339 without interfering with the current placement of the elements.
4340 </p>
4341 <p>
4342 If ever an element gets out of range you can either enlarge the paper
4343 size or click on the 'reset' button to place all elements below each
4344 other.
4345 </p>
4350 <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>

4368 existing language, where do I start?</a></h4>
4370 <p> Always use latest Git version of the po file to translate. You can optionally
4372 server</a> where you can also get the latest po files and merge them
4373 with your translations. For creating a new translation simply use
4377 to do this) or ask on the mailing list to add the translation to the web
4378 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Gettext_for_translators">our wiki</a>.
4379 </p>
4380 <p>
4381 Please note that we try not to use HTML entities like &eacute; in
4382 the translations, since we define the right character set in the file.
4383 With HTML entities, the text on JavaScript messages would not
4384 display correctly.
4385 However there are some entities that need to be there: quotes,
4386 non-breakable spaces, ampersands, less than, greater than.
4387 </p>
4388 <p>
4389 You can then put your translations, as a zip file to avoid losing special
4390 characters, on the sourceforge.net <a href="https://sourceforge.net/tracker/?group_id=23067&atid=387645">translation tracker.</a>
4391 </p>
4392 <p>
4393 It would be a good idea to subscribe to the <a href="https://lists.sourceforge.net/lists/listinfo/phpmyadmin-translators">phpmyadmin-translators</a> mailing
4394 list, because this is where we ask for translations of new messages.
4395 </p>
4397 <p>
4398 Documentation is being translated using po4a and gettext (see
4400 for existing translations). To start, checkout
4401 <a href="http://phpmyadmin.git.sourceforge.net/git/gitweb.cgi?p=phpmyadmin/localized_docs;a=tree;f=po"><code>localized_docs/po</code></a>
4402 from Git, or just go to the <a href="https://l10n.cihar.com/projects/pmadoc/">translation server</a>
4403 and translate it online. If your language is missing, just contact
4405 you prefer to directly translate the po files, please put updated ones into our

4429 <p>More details on git are available on <a href="http://wiki.phpmyadmin.net/pma/Git">our wiki</a>.</p>
4431 <p> Write access to the repository is granted only to experienced developers who
4432 have already contributed something useful to phpMyAdmin.<br />
4438 <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>
4440 <p> Please refer to

4442 </p>
4447 <p> If you use Apache web server, phpMyAdmin exports information about
4448 authentication to the Apache environment and it can be used in Apache logs.
4449 Currently there are two variables available:
4450 </p>
4451 <dl>
4453 <dd>User name of currently active user (he does not have to be logged
4454 in).</dd>
4461 </dl>
4462 <p>
4464 </p>
4465 <pre>
4468 </pre>
4469 <p>
4470 You can then use any log analyzing tools to detect possible break-in
4471 attempts.
4472 </p>
4478 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4479 It allows you to connect to local as well as remote servers. This requires you to enter
4480 server host name, username, password, port and the name of the database. Therefore you can
4481 now synchronize your databases placed on the same server or some remote server.
4482 </p>
4484 <p>
4485 This feature is helpful for developers who need to replicate their
4486 database’s structure as well as data. Moreover, this feature not only
4487 helps replication but also facilitates the user to keep his/her database
4488 in sync with another database. Other than the full database, certain
4489 tables of the databases can also be synchronized.
4490 </p>
4492 <p>
4493 You need to fill in the host name of the server, the username and
4494 password of an user account already there in MySQL. Port is by default
4495 populated with 3306 (MySQL default port). Then the name of the database
4496 should be mentioned at the end. All the information other than the port
4497 needs to be filled explicitly for the source as well as target servers.
4498 </p>
4500 <p>
4501 After successfully passing through the authentication phase, the source and
4502 target database table names will be displayed. It will be a tabular
4503 representation.
4504 </p>
4506 <p>
4507 On the left, are listed the source database table names. Some of the
4509 are only present in source database and they need to be added to the
4510 target database in order to synchronize the target database. The tables
4512 target database.
4513 </p>
4515 <p>
4516 On the right, are listed the target database table names. There are few
4518 means that these tables are to be created in target database in order to
4519 synchronize target database with source database. Some table names
4521 only present in target database and they will remain unchanged in the
4522 target database. The column in the middle shows the difference between
4523 the source and target corresponding tables.
4524 </p>
4526 <p>
4528 letters, indicating that either Structure or Data are not up to date. By
4529 clicking on them, they will turn grey, what means that they will be synchronized.

4911 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4912 to create a web-based interface to MySQL using PHP3. Although I have not
4913 used any of his source-code, there are some concepts I've borrowed from
4914 him. phpMyAdmin was created because Peter told me he wasn't going to
4915 further develop his (great) tool.
