- For Apache, you will need to make sure php_pdo.dll and php_pdo_mysql.dll exist in the php/ext directory, un-comment or add the appropriate lines in php.ini, and restart the web server.
- For IIS, PDO DLLs are not enabled by default. The preferred method for enabling them is to go to the Control Panel | Add/Remove Programs, highlight your PHP installation and click "Change" (Change/Remove - XP). Specify "FastCGI", then modify the installed extensions to include these two, then restart your server.
