Try doing the following test:

Download:
https://github.com/AzizSaleh/mysql

Extract it to a folder: X. Create a new file: wp-content/db.php and place this code in it (update pathToMySQL with path to your extracted folder X):

<?php
$pathToMySQL = 'C:\\xampp\\htdocs\\mysql\\';
require_once($pathToMySQL . 'MySQL_Definitions.php');
require_once($pathToMySQL . 'MySQL.php');
require_once($pathToMySQL . 'MySQL_Functions.php');

If that works, then this means that the admin section is running under a different PHP which doesn’t have pdo_mysql.so enabled.

If so, create a new php file in your admin section (call it php.info.php) and place in it:

<?php
phpinfo();

Then access that page and look for: Loaded Configuration File, which will give you the location of the php.ini it is using, which you will need to modify and uncomment:

extension=php_mysql.dll

Solution 1:

Check your php.ini and make sure that you have extension=php_mysql.dll un-commented.

Solution 2:

You can use the following library if you do not have mysql_connect enabled but have PDO enabled:

Create a new file: wp-content/db.php and place this code in it (update your path to mysql with path to your extracted folder):

<?php
$pathToMySQL = 'C:\\xampp\\htdocs\\mysql\\';
require_once($pathToMySQL . 'MySQL_Definitions.php');
require_once($pathToMySQL . 'MySQL.php');
require_once($pathToMySQL . 'MySQL_Functions.php');

Copy those files to a folder and then in your wordpress wp-includes/load.php file replace the following two lines:

wp_load_translations_early();
die( __( 'Your PHP installation appears to be missing the MySQL extension which is required by WordPress.' ) );

With the following:

$pathToMySQL = 'C:\\xampp\\htdocs\\mysql\\';
require_once($pathToMySQL . 'MySQL_Definitions.php');
require_once($pathToMySQL . 'MySQL.php');
require_once($pathToMySQL . 'MySQL_Functions.php');
