Your PHP installation appears to be missing the MySQL …

If you have a debian system, it’s as easy as:
apt-get install php5-mysql

Restart apache, and that is it!!

I am getting this error message on OS X 10.4.7 trying to install WordPress 2.0.3. I’ve got the default version of Apache 1.3.33 but with PHP 5.1.4 and MySQL 4.1.20.

I started up another thread as this is so Windows specific and I have an odd combination of versions.

I just want to note that for most applications you’re not going to notice a difference between PHP4 and PHP5 EXCEPT when PHP5 breaks things. For example, last I checked phpBB did not support PHP5, and I am fairly certain there are other major applications which don’t support it either.

Thank you all for your helpful diagnostic advice above. I used a combination of posts to solve the problem so here is a brief recount of what I did.

I have installations of
– PHP 5.1.4 (using the Windows Binaries PHP 5.1.4 installer)
– MySQL 5.0.22
– Microsoft IIS 5.1
all running on Windows XP locally.

Do the following steps:
1. See reply from “llbbl” (posted on 2005-09-27 22:25:00) and do steps 1, 2 and 3 (the explanatory paragraph at the end is useful also)
2. See post from “chebolsk” (posted on 2006-02-24 03:11:06) and do step 2.

That’s all that is required for this particular configuration.

I found the following to be useful when configuring WordPress to work with Windows XP, IIS 5.0 and PHP 5.1.6. I assume that IIS already serves up PHP pages and you’re getting the “Your PHP installation appears to be missing the MySQL which is required for WordPress” error.

1. Go to https://dev.mysql.com/downloads/ and select “MySQL Connector/PHP”

2. Download both the mysqli and mysql extensions.

3. Move the files that begin with “php_” to your extensions directory (usually c:\php\ext). Overwrite the existing files since these are NEWER and the LATEST from MySQL.

4. Move libmysql.dll to your PHP directory (C:\php). Overwrite the existing file (the one you’ve downloaded is NEWER). Both ZIP files will have the same libmysql.dll since after PHP 5.0.2 both the mysql and mysqli extensions use the same file.

5. Edit your php.ini file (in C:\php). Ensure the following lines exist and are NOT commented out:

extension=php_mysql.dll
extension=php_mysqli.dll

6. Ensure your extensions directory is set as well in the php.ini file:

extension_dir = “C:\php\ext”

7. Configure Windows so it can find PHP, its DLLS, and the php.ini file (this was the CRITICAL step for me, especially the PHPRC variable I describe):

Click Start -> Control Panel
Double-click System
Select the “Advanced” tab
Click the “Environment Variables” button
Under the “System variables” section, click the “Path” variable
Click the “Edit” button
Add “C:\php” to the path (no quotes). Note that each path is separated by a semicolon. Also, you should preferably add this EARLY in the path, since some of the MySQL DLLs may be included in other locations on your computer, and you’d like PHP to find the one installed in C:\php before it finds any other.
Click “OK”
Now, click the “New” button (again, in the “System variables” section)
For variable name, supply “PHPRC”
For variable value, supply “C:\php”
Click “OK” repeatedly until you’ve got all the windows closed.

8. Restart the computer so that these settings will be loaded and recognized by PHP. You can verify that your correct php.ini file is being loaded by testing a simple PHP page with the following:

<?php

phpinfo();

?>

If your settings are correct, you should see that “Configuration File (php.ini) Path” is “C:\php\php.ini” on the resulting page.

Hello all,

I had the same problem and it took me ages to identify the root cause of this issue. Here’s the solution on my blog:

PS: Check under PHP or WordPress section

All I had to do was install the PHP-MySQL+++++++.rpm file on the server and all was fine. I didn’t have to do any of the other stuff, it just worked after that.

I don’t know if any of you is still facing that problem, but what worked for me is copying libmysql.dll from MySQL Server 5.0\bin to c:\Windows

The command, apt-get install php4-mysql, will add the mysql module to php4 on Debian. Restart Apache. You should be good to go:)
