In my case, I also had to copy libmcrypt.dll to C:\Windows directory for mysqli section to show up in PHP information page. I’m using 64 bit Windows 2008 Server.

I had to do the following extra to make it work on 64bit Windows Server 2008 standard.

If you’re getting…

“HTTP Error 404.17 – Not Found – The requested content appears to be script and will not be served by the static file handler.”

on 64bit, but the ISAPI DLL is a 32-bit DLL, so you’ll have to either change your default Application Pool to enable 32-bit, or preferably create a separate 32-bit AppPool for your PHP Application.

Right click on the Application Pool and select “Advanced Settings” then “Enable 32-bit Applications.”

Anythoughts or suggestions greatly appreciated.

Do you know if these instructions for IIS7, PHP and MySQL will operate on a 64bit windows server?

Cheers

Here are a few things you need to verify:

1. Make sure PHP uses the right php.ini file. Sometimes people make changes to c:\php\php.ini while PHP looks for php.ini in c:\windows. See your phpinfo page for this information.

2. Make sure that “extension=php_mysql.dll” is uncommented in php.ini

3. Verify that libmysql.dll exists in c:\windows or c:\windows\system32

4. Have a look at IIS’ log files, you might find additional information regarding MySQL + PHP.

Let me know if this helps you out!

Try copying libmysql.dll (do a search) to c:\windows\system32 and restarting IIS.
