93 <!-- INTRODUCTION -->
96 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
97 a single database. To accomplish the latter you'll need a properly set up
98 MySQL user who can read/write only the desired database. It's up to you to
99 look up the appropriate part in the MySQL manual.

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>

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>
345 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
346 that you may need special (administrator) privileges to create the database
347 and tables, and that the script may need some tuning, depending on the
348 database name.</p>

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

369 is version-specific.</p>
372 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
373 you should run the SQL script found in
380 where you want to give users access to their own database and don't want
381 them to play around with others.<br />
382 Nevertheless be aware that MS Internet Explorer seems to be really buggy
384 in this area!<br />
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 />

544 The Swekey is a low cost authentication USB key that can be used in
545 web applications.<br /><br />
546 When Swekey authentication is activated, phpMyAdmin requires the
547 users's Swekey to be plugged before entering the login page (currently
548 supported for cookie authentication mode only). Swekey Authentication is
549 disabled by default.<br /><br />

1045 Since release 3.3.x a tracking mechanism is available.
1047 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1048 and data definition statements. After enabling it you can create versions of tables.
1049 <br/><br/>
1050 The creation of a version has two effects:
1052 <ul>
1054 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1055 </ul>
1057 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1058 For the report you can use filters, for example you can get a list of statements within a date range.
1059 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1060 In addition you can export the (filtered) report to a file or to a temporary database.

1863 each row on a vertical lineup.<br /><br />
1865 The HeaderFlipType can be set to 'css' or 'fake'. When using 'css'
1866 the rotation of the header for horizontalflipped is done via CSS. If

1877 no longer have to scroll. If you set this to integer, editing of fewer

2027 or icon is always displayed on the left panel. If JavaScript is enabled in
2028 your browser, a click on this opens a distinct query window, which is
2029 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2030 changes to display a query box.<br /><br />

2044 The usage of the JavaScript query window is recommended if you have a
2045 JavaScript enabled browser. Basic functions are used to exchange quite
2046 a few variables, so most 4th generation browsers should be capable to

2056 When using the JavaScript based query window, it will always get
2057 updated when you click on a new table/db to browse and will focus if
2058 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2059 the query window by checking the box "Do not overwrite this query from
2060 outside the window" below the query textarea. Then you can browse
2061 tables/databases in the background without losing the contents of the
2062 textarea, so this is especially useful when composing a query with
2063 tables you first have to look in. The checkbox will get automatically
2064 checked whenever you change the contents of the textarea. Please
2065 uncheck the button whenever you definitely want the query window to
2066 get updated even though you have made alterations.

2100 scratchboard where all your elements are placed. By clicking on an
2101 element, you can move them around in the pre-defined area and the x/y
2102 coordinates will get updated dynamically. Likewise, when entering a
2103 new position directly into the input field, the new position in the
2104 scratchboard changes after your cursor leaves the input field.<br />
2105 You have to click on the 'OK'-button below the tables to save the new
2106 positions. If you want to place a new element, first add it to the
2107 table of elements and then you can drag the new element around.<br />
2108 By changing the paper size and the orientation you can change the size
2109 of the scratchboard as well. You can do so by just changing the
2110 dropdown field below, and the scratchboard will resize automatically,
2111 without interfering with the current placement of the elements.<br />

2336 <!-- TRANSFORMATIONS -->
2342 </ol>
2346 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2348 section</a> on how to do so.</p>
2350 <p> You can apply different transformations to the contents of each field. The
2351 transformation will take the content of each field and transform it with
2352 certain rules defined in the selected transformation.</p>
2354 <p> Say you have a field 'filename' which contains a filename. Normally you would
2355 see in phpMyAdmin only this filename. Using transformations you can transform
2356 that filename into a HTML link, so you can click inside of the phpMyAdmin
2357 structure on the field's link and will see the file displayed in a new browser
2358 window. Using transformation options you can also specify strings to
2359 append/prepend to a string or the format you want the output stored in.</p>
2361 <p> For a general overview of all available transformations and their options,
2362 you can consult your
2363 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2364 installation.</p>
2366 <p> For a tutorial on how to effectively use transformations, see our
2368 the official phpMyAdmin homepage.</p>
2372 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2373 clicking on the 'Structure' link for a table). There click on
2374 "Change" (or change icon) and there you will see three new fields at
2375 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2376 'Transformation options'.</p>
2378 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2379 that corresponds to the column's contents. Please note that
2380 transformations are inactive as long as no MIME-type is selected.</li>
2382 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2383 hopefully growing amount of pre-defined transformations. See below for information on
2384 how to build your own transformation.<br />
2386 There are global transformations and mimetype-bound transformations. Global transformations
2387 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2388 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2389 transformations which operate on the main mimetype (like 'image'), which will most likely
2390 take the subtype into regard, and those who only operate on a
2391 specific subtype (like 'image/jpeg').<br />
2393 You can use transformations on mimetypes for which the function was not defined for. There
2394 is no security check for you selected the right transformation, so take care of what the
2395 output will be like.</li>
2397 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2398 transform-function specific options here. Usually the transforms can operate with default
2399 options, but it is generally a good idea to look up the overview to see which options are
2400 necessary.<br />
2402 Much like the ENUM/SET-Fields, you have to split up several options using the format
2403 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2404 parsed as an array, leaving the first value the first element in the array, and so
2405 forth.<br />
2407 If you want to specify a MIME character set you can define it in the transformation_options.
2408 You have to put that outside of the pre-defined options of the specific mime-transform,
2410 for which you can specify 2 options and you want to append a character set, enter "'first
2411 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2413 </ul>
2417 <p> All mimetypes and their transformations are defined through single files in
2418 the directory 'libraries/transformations/'.</p>
2420 <p> They are stored in files to ease up customization and easy adding of new
2421 transformations.</p>
2423 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2424 always work. It makes no sense to apply a transformation to a mimetype, the
2425 transform-function doesn't know to handle.</p>
2427 <p> One can, however, use empty mime-types and global transformations which should work
2428 for many mimetypes. You can also use transforms on a different mimetype they where built
2429 for, but pay attention to option usage as well as what the transformation does to your
2430 field.</p>
2432 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2433 any other transform function and provides some basic functions.</p>
2435 <p> There are 5 possible file names:</p>
2437 <ol><li>A mimetype+subtype transform:<br /><br />
2439 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2441 Please not that mimetype and subtype are separated via '_', which shall
2442 not be contained in their names. The transform function/filename may
2443 contain only characters which cause no problems in the file system as
2444 well as the PHP function naming convention.<br /><br />
2446 The transform function will the be called
2447 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2449 <b>Example:</b><br /><br />
2451 <tt>text_html__formatted.inc.php</tt><br />
2452 <tt>PMA_transform_text_html__formatted()</tt></li>
2454 <li>A mimetype (w/o subtype) transform:<br /><br />
2456 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2458 Please note that there are no single '_' characters.
2459 The transform function/filename may contain only characters which cause
2460 no problems in the file system as well as the PHP function naming
2461 convention.<br /><br />
2463 The transform function will the be called
2464 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2466 <b>Example:</b><br /><br />
2468 <tt>text__formatted.inc.php</tt><br />
2469 <tt>PMA_transform_text__formatted()</tt></li>
2471 <li>A mimetype+subtype without specific transform function<br /><br />
2473 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2475 Please note that there are no '__' characters in the filename. Do not
2476 use special characters in the filename causing problems with the file
2477 system.<br /><br />
2479 No transformation function is defined in the file itself.<br /><br />
2481 <b>Example:</b><br /><br />
2483 <tt>text_plain.inc.php</tt><br />
2484 (No function)</li>
2486 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2488 <tt>[mimetype].inc.php</tt><br /><br />
2490 Please note that there are no '_' characters in the filename. Do not use
2491 special characters in the filename causing problems with the file system.
2492 <br /><br />
2494 No transformation function is defined in the file itself.<br /><br />
2496 <b>Example:</b><br /><br />
2498 <tt>text.inc.php</tt><br />
2499 (No function)</li>
2501 <li>A global transform function with no specific mimetype<br /><br />
2503 <tt>global__[transform].inc.php</tt><br /><br />
2505 The transform function will the be called
2506 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2508 <b>Example:</b><br /><br />
2510 <tt>global__formatted</tt><br />
2511 <tt>PMA_transform_global__formatted()</tt></li>
2512 </ol>
2514 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2515 transform function.</p>
2517 <p> All filenames containing no '__' in themselves are not shown as valid transform
2518 functions in the dropdown.</p>
2520 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2521 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2522 without a transform function. Also note the introduction of a function description in
2523 the language files. For each function a $strTransformation_[filename without .inc.php]
2524 has to exist.</p>
2526 <p> You can use the template generator to generate new functions and entries in the
2527 language file.</p>
2529 <p> To create a new transform function please see
2530 <tt>libraries/transformations/template_generator.sh</tt>.
2531 To create a new, empty mimetype please see
2532 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2534 <p> A transform function always gets passed three variables:</p>
2536 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2537 you want to transform.</li>
2538 <li><b>$options</b> - Contains any user-passed options to a transform function
2539 as an array.</li>
2540 <li><b>$meta</b> - Contains an object with field information to your column.
2541 The data is drawn from the output of the
2543 function. This means, all object properties described on the
2545 available in this variable and can be used to transform a field accordingly
2546 to unsigned/zerofill/not_null/... properties.<br />
2547 The $meta->mimetype variable contains the original MIME-type of the
2548 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>

2649 We faced PHP crashes when trying to download a dump with MS Internet

2660 We recommend the following setup for Apache servers running in safe mode,
2661 to enable uploads of files while being reasonably secure:</p>
2663 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2664 <li>give ownership to the Apache server's user.group:
2665 <tt>chown apache.apache /tmp/php</tt></li>
2666 <li>give proper permission: <tt>chmod 600 /tmp/php</tt></li>

2678 So the problem is that this package has a serious bug that was corrected
2679 ages ago in PHP (2001-01-28: see

2746 </h4>
2748 <p> Starting with version 2.7.0, the import engine has been re–written and these
2749 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2750 to take advantage of the new import features.</p>
2752 <p> The first things to check (or ask your host provider to check) are the
2753 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2754 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2755 All of these three settings limit the maximum size of data that can be
2756 submitted and handled by PHP. One user also said that post_max_size
2757 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2759 There exist several workarounds if your upload is too big or your
2760 hosting provider is unwilling to change the settings:</p>

2772 <li>If you have shell (command line) access, use MySQL to import the files
2773 directly. You can do this by issuing the "source" command from
2774 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2775 </ul>
2779 support?</a></h4>
2781 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2782 older MySQL versions, you need to use 2.8.x branch. phpMyAdmin can
2783 connect to your MySQL server using PHP's classic

2787 good reason not to do so.<br />

2790 minor version since the one that is bundled with some PHP distributions is

2843 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called

2846 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried

2931 <p> This can happen due to a MySQL bug when having database / table names with

2933 To fix this, turn off this directive, convert all database and table names

2941 <p> It is possible to configure Apache in such a way that PHP has problems
2942 interpreting .php files.</p>
2944 <p> The problems occur when two different (and conflicting) set of directives
2945 are used:</p>

2958 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2959 The recommended way is with <tt>AddType</tt>, so just comment out
2960 the first set of lines and restart Apache:</p>

2976 <p> Yes.<br />
2977 However, phpMyAdmin needs to be backwards compatible to php4. This is why

3054 <p> If your cluster consist of different architectures, PHP code used for

3056 pack/unpack functions in code. Only solution is to use mcrypt extension
3057 which works fine in this case.</p>
3062 <p> Yes but the default configuration values of Suhosin are known to cause
3063 problems with some operations, for example editing a table with many
3064 columns and no primary key or with textual primary key.
3065 </p>
3066 <p>
3067 Suhosin configuration might lead to malfunction in some cases and it can
3068 not be fully avoided as phpMyAdmin is kind of application which needs to
3069 transfer big amounts of fields in single HTTP request, what is something
3070 what Suhosin tries to prevent. Generally all
3071 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3072 <code>suhosin.get.*</code> directives can have negative effect on
3073 phpMyAdmin usability. You can always find in your error logs which limit
3074 did cause dropping of variable, so you can diagnose the problem and adjust
3075 matching configuration variable.
3076 </p>
3077 <p>
3078 The default values for most Suhosin configuration options will work in most

3107 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work,</a></h4>
3109 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />

3118 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3119 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.

3168 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3170 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3171 In your <i>php.ini</i> you will find a line</p>
3173 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3175 <p> change it to</p>
3177 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3179 <p> Then restart apache and it will work.</p>
3181 <p> Here is a fix suggested by Brad Ummer:</p>
3183 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3184 To do this, telnet to your server and go to the MySQL bin directory. In
3185 this directory there should be a file named <i>mysqladmin</i>. Type
3186 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3187 info about your MySQL server, including the socket
3188 (<i>/tmp/mysql.sock</i>, for example).</li>

3211 sometime.<br />
3212 Also have a look at your PHP version number: if it contains "4.0b..."
3213 it means you're running a beta version of PHP. That's not a so good idea,

3223 directive in the phpMyAdmin configuration file.</p>
3227 password: YES)"-error when trying to access a MySQL-Server on a
3228 host which is port-forwarded for my localhost.</a></h4>
3230 <p> When you are using a port on your localhost, which you redirect via
3231 port-forwarding to another host, MySQL is not resolving the localhost
3232 as expected.<br />
3233 Erik Wasser explains: The solution is: if your host is "localhost"
3234 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
3235 connection for speeding up things. And that doesn't work in this configuration
3236 with port forwarding.<br />
3242 <p> Themes are configured with
3246 <br />
3248 should not delete the directory "original" or its underlying
3249 structure, because this is the system theme used by phpMyAdmin.
3250 "original" contains all images and styles, for backwards
3251 compatibility and for all themes that would not include images or css-files.
3252 <br /><br />
3255 is enabled, you can select your favorite theme on the main page. Your
3256 selected theme will be stored in a cookie.<br /><br /></p>
3258 <p> To create a theme:</p>
3260 <ul><li>make a new subdirectory (for example "your_theme_name") under
3262 (by default <tt>themes</tt>)</li>
3263 <li>copy the files and directories from "original" to
3264 "your_theme_name"</li>
3265 <li>edit the css-files in "your_theme_name/css"</li>
3266 <li>put your new images in "your_theme_name/img"</li>
3267 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
3268 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
3269 contain your chosen theme name, that will be visible in user interface</li>
3270 <li>make a new screenshot of your theme and save it under
3271 "your_theme_name/screen.png"</li>
3272 </ul>
3274 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3275 theme verbose name, theme generation and theme version. These versions and
3276 generations are enumerated from 1 and do not have any direct dependence on
3277 phpMyAdmin version. Themes within same generation should be backwards
3278 compatible - theme with version 2 should work in phpMyAdmin requiring
3279 version 1. Themes with different generation are incompatible.</p>
3281 <p> If you do not want to use your own symbols and buttons, remove the
3282 directory "img" in "your_theme_name". phpMyAdmin will
3283 use the default icons and buttons (from the system-theme "original").
3284 </p>
3288 what can I do?</a></h4>
3290 <p> Here are a few points to check:</p>
3292 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3294 directive empty. See also
3296 </li>
3297 <li>Maybe you have a broken PHP installation or you need to upgrade
3298 your Zend Optimizer. See
3300 http://bugs.php.net/bug.php?id=31134</a>.
3301 </li>
3302 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3303 set to the default (200) or another low value, you could get this
3304 error if your table has a high number of columns. Adjust this setting
3305 accordingly. (Thanks to Klaus Dorninger for the hint).
3306 </li>
3307 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3308 of ";" will cause this error. Replace it with "&;".
3309 </li>
3311 you might want to increase
3313 </li>
3314 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3315 </li>
3316 </ul>
3321 <p> To be able to see a progress bar during your uploads, your server must
3324 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3325 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3332 who logged out can not log in again in with the same nick.</a></h4>
3334 <p> This is related to the authentication mechanism (protocol) used by
3335 phpMyAdmin. To bypass this problem: just close all the opened
3336 browser windows and then go back to phpMyAdmin. You should be able to
3337 log in again.</p>
3341 limit error or a time limit error.</a></h4>
3343 <p> Compressed dumps are built in memory and because of this are limited to
3344 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3345 using
3347 (enabled by default). Zip exports can not be handled this way, so if you need
3348 Zip files for larger dump, you have to use another way.</p>
3352 when I rename a table or a column.</a></h4>
3354 <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>
3358 bundled with the MySQL server distribution.</a></h4>
3360 <p> The problem is that older versions of mysqldump created invalid comments like this:</p>
3362 <pre>
3363 -- MySQL dump 8.22
3364 --
3365 -- Host: localhost Database: database
3366 ---------------------------------------------------------
3367 -- Server version 3.23.54
3368 </pre>
3370 <p> The invalid part of the code is the horizontal line made of dashes that
3371 appears once in every dump created with mysqldump. If you want to run your
3372 dump you have to turn it into valid MySQL. This means, you have to add a
3373 whitespace after the first two dashes of the line or add a # before it:
3374 <br />
3375 <code>
3376 -- -------------------------------------------------------<br />
3377 </code>
3378 or<br />
3379 <code>
3380 #---------------------------------------------------------
3381 </code>
3382 </p>
3389 <p> Please note that you should not use the separating string multiple times
3390 without any characters between them, or at the beginning/end of your table
3391 name. If you have to, think about using another TableSeparator or disabling
3392 that feature</p>

3398 or having more than one index field in the foreign key.<br /><br/>

3400 LEFT JOIN from the foreign table.<br /><br/>
3401 </p>
3405 I get series of errors like "Warning: unable to parse url". How
3406 can this be fixed?</a></h4>
3407 <p>
3408 Your table neither have a primary key nor an unique one, so we must use a
3409 long expression to identify this row. This causes problems to parse_url
3410 function. The workaround is to create a primary or unique key.
3411 <br />
3412 </p>
3416 a MIME-Transformation onto!</a></h4>
3418 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3419 nested forms can be put inside the table where phpMyAdmin displays the results.
3420 You can, however, use any form inside of a table if keep the parent
3421 form-container with the target to tbl_row_delete.php and just put your own
3422 input-elements inside. If you use a custom submit input field, the form will
3423 submit itself to the displaying page again, where you can validate the
3424 $HTTP_POST_VARS in a transformation.
3426 For a tutorial on how to effectively use transformations, see our
3428 on the official phpMyAdmin-homepage.</p>
3432 MySQL server</a></h4>
3434 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3437 http://dev.mysql.com/doc/mysql/en/ANSI_mode.html</a>). Most important of all,
3438 the quote-character (") is interpreted as an identifier quote character and
3439 not as a string quote character, which makes many internal phpMyAdmin
3441 statements. There is no workaround to this behaviour. News to this item will
3442 be posted in Bug report
3443 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>

3448 more that one column with the same value
3449 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3450 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3452 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3453 can use it for the Edit and Delete links.</p>
3458 <p> phpMyAdmin uses a quick method to get the row count, and this method
3459 only returns an approximate count in the case of InnoDB tables. See
3461 a way to modify those results, but
3462 this could have a serious impact on performance.</p>
3467 <p> The number of records in queries containing COUNT and GROUP BY is
3468 not correctly calculated. Also, sorting results of a query like
3473 containing an hyphen.
3474 </a></h4>
3475 <p>
3476 The tests I have made with current MySQL 4.1.11 API shows that the
3477 API does not accept this syntax for the USE command. Enclosing the
3478 db name with backquotes works. For further confusion, no backquotes
3479 are needed with command-line mysql.

3483 <a href="#faq3_14">3.14 I am not able to browse a table when I don't have the right to SELECT one of the columns.</a></h4>
3484 <p>
3485 This has been a known limitation of phpMyAdmin since the beginning and
3486 it's not likely to be solved in the future.

3489 <!-- Begin: Excel import limitations -->
3492 <a href="#faq3_15">3.15 When I import an Excel spreadsheet, some cells with calculations do not display correctly.</a></h4>
3493 <p>
3494 phpMyAdmin uses the <a href="http://www.codeplex.com/PHPExcel/" target="_blank">PHPExcel</a> library to parse Excel XLS and XLSX spreadsheets.
3495 Therefore, any limitations that are listed on their page regarding Excel calculations will also apply here.
3496 <br /><br />
3497 PHPExcel will be kept up to date so as to make all improvements available to phpMyAdmin users.

3501 <a href="#faq3_16">3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import it, nothing happens.</a></h4>
3502 <p>
3503 Since Excel XLSX workbooks are already compressed, there is often times only a small benefit from compressing them yet again.
3504 Support for compressed Excel XLSX and XLS workbooks may be added in the future.
3505 </p>
3508 <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>
3509 <p>
3510 Excel's internal representation of custom cell types is rather muddled (especially in Excel 97-2003 binary XLS files). If possible,
3511 consider using a built-in type. These are almost always guarenteed to import correctly.

3518 <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>
3519 <p>
3520 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.

3527 <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>
3528 <p>
3529 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
3530 you will have to edit the structure to your liking post-import.
3531 <br /><br />
3532 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
3533 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.

3904 in this document.
3905 </p>
3910 <p> Here is an example with the tables persons, towns and countries, all
3912 table, create it as explained in the configuration section. Then create the
3913 example tables:</p>
3915 <pre>
3916 CREATE TABLE REL_countries (
3917 country_code char(1) NOT NULL default '',
3918 description varchar(10) NOT NULL default '',
3919 PRIMARY KEY (country_code)
3920 ) TYPE=MyISAM;
3922 INSERT INTO REL_countries VALUES ('C', 'Canada');
3924 CREATE TABLE REL_persons (
3925 id tinyint(4) NOT NULL auto_increment,
3926 person_name varchar(32) NOT NULL default '',
3928 country_code char(1) NOT NULL default '',
3929 PRIMARY KEY (id)
3930 ) TYPE=MyISAM;
3932 INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
3933 INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');
3935 CREATE TABLE REL_towns (
3937 description varchar(30) NOT NULL default '',
3938 PRIMARY KEY (town_code)
3939 ) TYPE=MyISAM;
3941 INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
3942 INSERT INTO REL_towns VALUES ('M', 'Montréal');
3943 </pre>
3949 <li>in Links, for "country_code" choose "REL_countries->country_code"</li>
3953 </ul>
3961 <li>In the fields row, choose persons.person_name and click the
3963 <li>Do the same for towns.description and countries.descriptions in the
3966 the correct joins have been generated</li>
3968 </ul>
3972 <p>
3973 Starting from the previous example, create the pma_table_info as explained
3974 in the configuration section, then browse your persons table,
3975 and move the mouse over a town code or country code.
3976 <br /><br />
3977 See also <a href="#faq6_21"><abbr title="Frequently Asked Questions">FAQ</abbr> 6.21</a> for an additional feature that "display field"
3978 enables: drop-down list of possible values.
3979 </p>
3982 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3983 <p>
3986 <br /><br />
3987 Then you need to think about your schema layout. Which tables will go on
3988 which pages?
3989 </p>
3990 <ul>
3996 page and click Go. If you like, you
3998 linked tables onto the new page.</li>
3999 <li>Select the name of the new page (making sure the Edit radio button
4000 is selected) and click Go.</li>
4002 Coordinates are relative; your diagram will
4003 be automatically scaled to fit the page. When initially placing tables
4004 on the page, just pick any coordinates -- say, 50x50. After clicking
4006 position the element correctly.</li>
4008 first be sure to click the Save
4009 button beneath the list of tables and coordinates, to save any changes
4010 you made there. Then scroll all the way down, select the
4012 you want, and click Go.</li>
4013 <li>Internet Explorer for Windows may suggest an incorrect filename when
4018 browsers on Windows, do not have this problem.</li>
4019 </ul>
4023 columns!</a></h4>
4025 <p> No, it's MySQL that is doing
4031 underscores in the database name?</a></h4>
4033 <p> If you do not put a backslash before the underscore, this is a wildcard
4036 john2db ...<br /><br />
4038 If you put a backslash before the underscore, it means that the database
4039 name will have a real underscore.</p>
4043 statistics pages?</a></h4>
4054 if it already exists during the import. It does NOT drop the table after
4055 your export, it only affects the import file.</li>
4057 Otherwise, you may get an error if the table name exists but has a
4058 different structure.</li>
4060 (if any) will be included in backup.</li>
4062 field and table names formed with special characters are protected.</li>
4064 types set in the pmadb in the dump as
4066 </li>
4067 </ul>
4072 command, for better documentation (but resulting file is bigger).</li>
4074 once the INSERT verb and the table name.</li>
4077 </li>
4079 more info is provided in the
4081 but basically with this selected, invalid values are adjusted and
4082 inserted rather than causing the entire statement to fail.</li>
4083 </ul>
4087 in its name.</a></h4>
4090 is the normal way to reference a database and table name. Worse, MySQL
4091 will usually let you create a database with a dot, but then you cannot
4092 work with it, nor delete it.</p>
4105 for usage.<br />
4106 On a more recent pear version, I had problems with the state of Net_DIME
4107 being beta, so this single command
4109 needed modules.<br />
4110 If you use the Validator, you should be aware that any
4112 submit will be stored anonymously (database/table/column names,
4113 strings, numbers replaced with generic values). The Mimer
4116 We utilize it as free SOAP service.</p>
4120 it, but MySQL says "BLOB column '...' used in key specification without
4123 <p> The right way to do this, is to create the field without any indexes,
4125 dialog. On this page, you will be able to choose your BLOB field, and
4126 set a size to the index, which is the condition to create an index on
4127 a BLOB field.</p>
4131 editing fields?</a></h4>
4133 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4134 with many editing fields (table structure changes, row editing, etc.)
4135 (must be enabled in configuration - see.
4137 You can also have a look at the directive
4139 ('vertical') and see if this eases up editing for you.</p>
4143 WTF is this feature then useful for?</a></h4>
4145 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4146 on them. Otherwise you could just put a comment on the field. Because entering
4147 your own mimetype will cause serious syntax checking issues and validation,
4148 this introduces a high-risk false-user-input situation. Instead you have to
4149 initialize mimetypes using functions or empty mimetype definitions.<br />
4150 Plus, you have a whole overview of available mimetypes. Who knows all those
4151 mimetypes by heart so he/she can enter it at will?</p>
4155 can't I see any bookmarks below the query box? What is this variable for?
4156 </a></h4>
4158 <p> Any query you have executed can be stored as a bookmark on the page where the
4159 results are displayed. You will find a button labeled 'Bookmark this query'
4160 just at the end of the page.<br />
4161 As soon as you have stored a bookmark, it is related to the database you run
4162 the query on. You can now access a bookmark dropdown on each page, the query
4163 box appears on for that database.<br /><br />
4165 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4169 aware of that you HAVE to create a valid query, otherwise your query won't be
4170 even able to be stored in the database.<br />
4172 for your query will remain the way it is, but will be stripped of the /**/
4173 chars. So you can use:<br /><br />
4177 which will be expanded to<br /><br />
4181 in your query, where VARIABLE is the string you entered in the input box. If
4182 an empty string is provided, no replacements are made.<br /><br />
4184 A more complex example. Say you have stored this query:<br /><br />
4186 <br /><br />
4189 the full query will be:<br /><br />
4192 <br /><br />
4196 spaces inserted there
4197 will be later also inserted as spaces in your query and may lead to unexpected
4198 results especially when
4200 Your initial query which is going to be stored as a bookmark has to yield at
4201 least one result row so
4202 you can store the bookmark. You may have that to work around using well
4206 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4207 include exported table?</a></h4>
4209 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4210 document should look like following one (assuming you have table
4213 <pre>
4214 \documentclass{article} % or any class you want
4215 \usepackage{longtable} % for displaying table
4216 \begin{document} % start of document
4217 \include{table} % including exported table
4218 \end{document} % end of document
4219 </pre>
4223 access them.
4224 </a></h4>
4227 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4228 enable users to see all the database names.
4231 So if your users do not need those privileges, you can remove them and their
4232 databases list will shorten.</p>
4236 possible values for a field, based on some foreign table?</a></h4>
4238 <p> You have to setup appropriate links between the tables, and also
4242 foreign table, a drop-down list of values will be available.
4243 You will see two lists of values, the first list containing the key
4244 and the display field, the second list containing the display field
4245 and the key. The reason for this is to be able to type the first
4246 letter of either the key or the display field.<br /><br />
4248 For 100 values or more, a distinct window will appear, to browse foreign
4249 key values and choose one. To change the default limit of 100, see
4250 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4254 automatically when entering Browse mode for a table?</a></h4>
4256 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
4257 </p>
4261 Excel files, how can I enable that?</a></h4>
4263 <p> Current version does support direct export to Microsoft Excel and Word
4264 versions 2000 and newer. If you need export older versions, you can use
4266 which works out of the box or you can
4268 several problems, most important are limitation of cell content to 255
4269 chars and no support for charsets, so think carefully whether you want to
4270 enable this.</b>. For enabling this you need to set
4274 module Spreadsheet_Excel_Writer into php include path. The
4275 installation can be done by following command:</p>
4277 <pre>
4278 pear -d preferred_state=beta install -a Spreadsheet_Excel_Writer
4279 </pre>
4281 <p> First part of switches set we want to install beta version of that module
4282 (no stable version available yet) and then we tell pear we want to satisfy
4283 dependencies.</p>
4285 <p> If you are running in PHP safe mode, you will have to set
4288 modules are located, for example:</p>
4290 <pre>
4291 safe_mode_include_dir = /usr/local/lib/php
4292 </pre>
4296 <pre>
4297 cd phpMyAdmin
4298 mkdir tmp
4299 chmod o+rwx tmp
4300 </pre>
4304 what happens to my column comments stored in pmadb?</a></h4>
4306 <p> Automatic migration of a table's pmadb-style column comments to the native
4307 ones is done whenever you enter Structure page for this table.</p>
4312 <p> First, for general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. We currently support streaming if you are running MySQL 5.1 with the PBXT and PBMS storage engines.</p>
4314 <ol>
4315 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of something like "localhost".</li>
4316 <li>A current limitation is that your first login via phpMyAdmin to a freshly-started server must be done with an account that has the SUPER privilege.</li>
4317 <li>On your target database, go to Operations and in the "BLOB Repository" section, click "Enable". This creates the PBMS system tables inside your database.</li>
4318 <li>Ensure that your target table is under the PBXT storage engine and has a LONGBLOB column.</li>
4319 <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 column instead of the repository.</li>
4320 <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 but in case it's incorrect, it's possible to edit it by clicking on the displayed MIME-type.</li>
4321 </ol>
4328 <p> Our Bug Tracker is located at
4330 under the Bugs section.<br /><br />
4332 But please first discuss your bug with other users:<br />
4338 existing language, where do I start?</a></h4>
4340 <p> Always use the current SVN version of your language file.
4342 don't know how to get the SVN version, please ask one of the developers.
4343 <br />
4344 Please note that we try not to use HTML entities like &eacute; in
4345 the translations, since we define the right character set in the file.
4346 With HTML entities, the text on JavaScript messages would not
4347 display correctly.
4348 However there are some entities that need to be there, for quotes
4349 ,non-breakable spaces, ampersands, less than, greater than.<br />
4350 You can then put your translations, as a zip file to avoid losing special
4351 characters, on the sourceforge.net translation tracker.<br />
4352 It would be a good idea to subscribe to the phpmyadmin-translators mailing
4353 list, because this is where we ask for translations of new messages.</p>
4357 phpMyAdmin. How should I proceed?</a></h4>
4362 <tt>git clone
4363 git://phpmyadmin.git.sourceforge.net/gitroot/phpmyadmin/phpmyadmin</tt><br />
4364 </li>
4366 <li>generate patch with your changes:

4372 </li>
4373 </ol>
4375 <p>More details on git are available on <a href="http://wiki.phpmyadmin.net/pma/Devel:Git">our wiki</a>.</p>
4377 <p> Write access to the repository is granted only to experienced developers who
4378 have already contributed something useful to phpMyAdmin.<br />
4384 <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>
4386 <p> Please refer to
4387 <a href="http://www.phpmyadmin.net/home_page/security.php">http://www.phpmyadmin.net/home_page/security.php</a>
4388 </p>
4393 <p> If you use Apache web server, phpMyAdmin exports information about
4394 authentication to Apache environment and it can be used in Apache logs.
4395 Currently there are two variables available:
4396 </p>
4397 <dl>
4399 <dd>User name of currently active user (he does not have to be logged
4400 in).</dd>
4407 </dl>
4408 <p>
4410 </p>
4411 <pre>
4414 </pre>
4415 <p>
4416 You can then use any log analyzing tools to detect possible break-in
4417 attempts.
4418 </p>
4424 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4425 It allows you to connect to local as well as remote servers.This requires you to enter
4426 server host name, username, password, port and the name of the database. Therefore you can
4427 now synchronize your databases placed on the same server or some remote server.
4428 </p>
4430 <p>For more details see <a href="./documentation-gsoc/Synchronization_User_Manual.htm">How to synchronize</a>

4768 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4769 to create a web-based interface to MySQL using PHP3. Although I have not
4770 used any of his source-code, there are some concepts I've borrowed from
4771 him. phpMyAdmin was created because Peter told me he wasn't going to
4772 further develop his (great) tool.

4774 <p>
4775 Thanks go to
4776 </p>
4777 <ul>
4779 code for the check when dropping a table or database. He also suggested
4780 that you should be able to specify the primary key on tbl_create.php3. To
4781 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4782 well as a bug-report. Plus many smaller improvements.
4783 </li>
4785 were introduced in 1.3.0 (including quite significant ones like the
4786 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4787 bug-fixes and help.
4788 </li>
4790 language-independent by outsourcing the strings to a separate file. He
4791 also contributed the French translation.
4792 </li>
4794 tbl_select.php3, a feature to display only some fields from a table.
4795 </li>
4797 functions in tbl_change.php3. He also added the
4799 </li>
4801 servers and is a regular contributor for bug-fixes.
4802 </li>
4804 features for 2.0.6.
