For example, if you want user sessions to stay in your database // for three weeks before deleting them, you need to set gc_maxlifetime // to '1814400'. At that value, only after a user doesn't log in after // three weeks (1814400 seconds) will his/her session be removed. $this->connection->delete('sessions') ->condition('timestamp', REQUEST_TIME - $lifetime, '<') ->execute(); return TRUE; }
