Answer 1

Sorry for bad english!

Create a file named info.php with this content:

<?php
phpinfo();
?>

Save and put in your server root.
Access http://localhost/info.php
See what PDO Drivers are loaded (CTRL + F and type PDO drivers).
MySql PDO Driver need to be loaded like this:

If you don't see mysql on PDO drivers, you should edit php.ini and add extension=pdo_mysql.dll
Restart your Apache and try again in info.php

PS: Certify that you have the pdo_mysql.dll in your PHP extensions folder.

Answer 2

To anyone that don't know where is the extension folder. Go to PHP.ini and search for: extension_dir And how you can see in the image, thats the path.
