Installing Wordpress - constant PHP/MySQL extension appears missing

Question

I've got Win2003 w/IIS6, PHP 5 and MySQL installed. I can confirm PHP is installed correctly because I have a testMe.php that runs properly. When I run the Wordpress setup, I get informed that

Your PHP installation appears to be missing the MySQL extension which is required by WordPress.

But in my PHP.ini in the DYNAMIC EXTENSIONS section I have

extension=php_mysql.dll
extension=php_mysqli.dll

I verified that mysql.dll and libmysql.dll are both in my PHP directory. I copied my libmysql.dll to the C:\Windows\System32 directory.

When I try to run the initial setup for WordPress, I get this answer. I've Googled setting this up, and everything comes down to the above. I'm missing something, but none of the instructions that I've found online seem to cover whatever that is.

Answer 1

You should try putting the files in the PHP extension directory, which is usually something like:

c:\Program Files\PHP\ext

The best way to check of course is to do what tim said and look in the phpinfo() results for the extension directory location.

Answer 2

Create a php info file

<?php phpinfo(); ?>

and then see that file in your server, and see if really that extension is loaded
