Your PHP installation appears to be missing the MySQL which is required for WP

You need to edit your PHP installation to load the mysql library. Look at your PHP.INI file. Search for “mysql” in it. It may be as simple as uncommenting the line that reads:
extension=php_mysql.dll
Or it may be more complicated than that. Hard to say without looking at your installation.

Tried that with no difference. Someone else told me to remove if ( !extension_loaded(‘mysql’) && !file_exists(ABSPATH . ‘wp-content/db.php’) )
die( ‘Your PHP installation appears to be missing the MySQL which is required for WordPress.’ ); from my wp-settings.php file. Now I get a blank page. Any other suggestions?

If it helps, when I run php-win against install.php at a Command Prompt, it appears to work. It just doesn’t in IE or FireFox.

I figured it out. I had forgotten to give my IUSR user access to the c:\php directory. Silly me! ??

Folks,

I had the same problem with the same err msg.

Here’s how I solved it.
– Looked at Apache error.log. It pointed to php_mysql.dll not being loaded

– In php.ini file, fixed the “extension_dir” to point to “./ext/” (since I’m using PHP5)

– Restarted Apache.

Hope this helps somebody.

ENV: Apache 2.2.4; PHP 5; WordPress 2.1

Hello,

I couldn’t get it to work with IIS 5.1 on XP Pro SP2, so I installed Apache and that worked. (I didn’t use any of the user tips on this site) I picked up a book on PHP & MySQL and followed it’s installation instructions for Apache, PHP and MySQL. I bought the 2007 edition. It’s sad that many technical books on the shelf are obsolete. The first one I tried was two years old and was a waste of time.

Environ: Apache 2.2.4; PHP 5.2.0: MySQL 5.0; WordPress 2.1

Yup, that works. But the best way every time is xampp from https://www.apachefriends.org/en/xampp.html – they’ve already done all the hard work….

There are similar versions for linux and mac.

Ran into the same problem. Using IIS 6 with PHP 5 and FastCGI. PHP is installed at C:\PHP manually using threading-unsafe manual deployment (see https://www.iis.com/php)

Made sure to add IUSR_COMPUTERNAME and “Network Service” to have read/execute access to C:\PHP. (This was already configured at the wordpress directory location.)

Modified php.ini so that instead of ‘./’ as the extensions directory it was ‘C:\PHP\ext\’. I had changed it to ‘C:\PHP\’ but apparently that was incorrect.

Also removed the comment (semi-colon) behind the mysql DLL,

.. from ..

;extension=php_mysql.dll

.. to ..

extension=php_mysql.dll

Start menu, Run…, “iisreset”

Works.

Still having issues with this. Mysql does not reside on the same server but that should not matter. I have my cfg file pointing to the proper ip, correct? I’m rreally stumped on this one. I have spent countless hours configuring and reconfiguring things. Tripple checking setting and I still get the dreaded “Your PHP installation appears to be missing the MySQL which is required for WP” page. Any ideas on what I could be missing?

I have found multiple sites with the above solutions, plus gobs more about copying .dll’s and .ini’s back and forth from the php/ext dir, mysql/bin dir, and winnt/dir. Still no go. Apache error.log says nothing is wrong, and I am able to do all of my other PHP and MySQL fine on my local server. Queries all work, etc. The only thing that doesn’t work is WP. So maybe someone sees a problem with my test.php output:

msql
MSQL Support enabled
Allow Persistent Links yes
Persistent Links 0/unlimited
Total Links 0/unlimited

mysqli
MysqlI Support enabled
Client API version 4.1.7
MYSQLI_SOCKET /tmp/mysql.sock

Directive Local Value Master Value
mysqli.default_host no value no value
mysqli.default_port 3306 3306
mysqli.default_pw no value no value
mysqli.default_socket no value no value
mysqli.default_user no value no value
mysqli.max_links Unlimited Unlimited
mysqli.reconnect Off Off

after a full day of searching i found the solution to this problem….at least for me. It seems all I had to do was add ISS_IUSRS as a user on the php.exe. Did that and everything works great now. Just thought I’d share
