PDO are not ported yet, so you can't use that driver.

This is probably why it was not working! Do you know configuration settings for PDO is explained in the documentation : https://codeigniter.com/user_guide/datab...figuration

Some database drivers (such as PDO, PostgreSQL, Oracle, ODBC) might require a full DSN string to be provided. If that is the case, you should use the ‘DSN’ configuration setting, as if you’re using the driver’s underlying native PHP extension, like this:

Code:

// PDO
$default['DSN'] = 'pgsql:host=localhost;port=5432;dbname=database_name';
