How can I use PDO in CI3.

I searched on google. But not found any proper solution.

Try this in your database configuration (e.g. for mysql)

PHP Code:

    'dsn'    => 'mysql:host=host_name;dbname=db_name',
    'username' => 'usr',
    'password' => 'pw',
    'database' => 'db',
    'dbdriver' => 'pdo', 


If i config only 'dsn' than i think 'database' and 'server' field will not use if i comment both than its not work but when i comment out dsn than its also works.

And 'dbdriver' => 'pdo' // show me invalid data driver

Its working now. what the hell with yesterday same setting but not worked yesterday but wholla works today fine.
