2.14.5.9. Change database driver in Drupal

Driver options:

• MySQL (only for PHP versions below 5.5).
• MySQLi
• PDO

To change the driver, perform the following:

1. Open the database connection settings in the site's configuration file.
2. Find the line:

   • Drupal 7-8
   • Drupal 6

   'driver' => 'XXXXX',

   $db_url = 'XXXXX://login:password@host/database';

3. Instead of XXXXX, specify the required driver.
