2.13.5.9. Changing the database driver in Drupal

Driver options:

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

To change the driver, do the following:

1. Openup database connection settings in the site config file.
2. Find the line:

   • Drupal 7-8
   • Drupal 6

   'driver' => 'XXXXX',

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

3. Instead XXXXX specify the required driver.
