HOW TO INCREASE THE SESSION EXPIRY TIME IN PHP

OPTIONS: (1) Editing the php.ini (2)Alter the session maximun life time through php script using ini_set()


Editing the PHP configuration file php.ini:

In order to change the session timeout, the change needs to be made in the PHP configuration file php.ini. In some distributions, this file is stored in /etc/php.ini. In Ubuntu and some other distributions, this file is stored in /etc/php5/apache2/php.ini. This setting is controlled by session.gc_maxlifetime. What this setting does is to control the session cleanup. After making any changes to this setting in the php.ini, make sure you restart apache to ensure that the version of PHP being used by Apache is updated with your configuration changes.




Editing the PHP configuration file steeing via php script

To find out what the default (file-based-sessions) session timeout value on the server is you can view it through a ini_get command:



    // Get the current Session Timeout Value
    $currentTimeoutInSecs = ini_get(’session.gc_maxlifetime’);

echo($currentTimeoutInSecs);

    // Change the session timeout value to 30 minutes  // 8*60*60 = 8 hours
    ini_set(’session.gc_maxlifetime’, 30*60);
    //————————————————————————————–

// php.ini setting required for session timeout.

ini_set(‘session.gc_maxlifetime’,3000);
ini_set(‘session.gc_probability’,1);
ini_set(‘session.gc_divisor’,1);
?>
