Problem with session

My session-variables are:

PHP Code:

public $sessionDriver            = 'CodeIgniter\Session\Handlers\FileHandler';
public $sessionCookieName        = 'ci_session';
public $sessionExpiration        = 7200;
public $sessionSavePath          = WRITEPATH . 'session';
public $sessionMatchIP           = false;
public $sessionTimeToUpdate      = 300;
public $sessionRegenerateDestroy = false; 


is this helpful?
