Any Drupal guru's in the forum,I have a quick one for y'all

Scenario:

I have a site done in Drupal.I have a hosting service and am ready to upload the site.I have edited the settings.php file to reflect my username and password(i.e $db_url = 'mysqli://aca_root:xxxxxx@localhost/aca';) and the baseurl: www.mydomain.com) of the db which is done in mysql.When uploading and running the domain name,I get this error

" Unable to use the MySQLi database because the MySQLi extension for PHP is not installed. Check your <code>php.ini</code> to see how you can enable it.."

Any solutions or any pointers?

Regards,
