PHP session expires before time

Question

I have a problem with a session time in PHP with Codeigniter. I was using the sessions in the IC and with so many problems I decided to look for a solution to use native sessions with the IC and at first it has already improved, but still it continues to fall the session before the predetermined time.

In the settings I set the sess_expiration 7200 (CI default value) and every time I don’t touch the system for a certain time (I’ve done several tests like 10min, 30min, 1h) and almost always falls when I update the page.

I played the code in Pastebin to make it easier to read it.

And inspecting the firebug, in Resouces->Cookies the Expires / Max-Age theoretically correct.

Here’s my session job:

function sessionTimeout($time_out)//em minutos
{
    $time_out= 60*$time_out;//passa para segundos

    ini_set('session.gc-maxlifetime', $time_out);

    if (isset($_SESSION['LAST_ACTIVITY']) && (time() - $_SESSION['LAST_ACTIVITY'] > $time_out)) 
    {
        // último pedido foi a mais de $time_out atrás
        session_unset();     // unset $_SESSION variable for the run-time
        session_destroy();   // destroy session data in storage
    }
    $_SESSION['LAST_ACTIVITY'] = time(); // atualiza a hora da última atividade

    if (!isset($_SESSION['CREATED'])) 
    {
        $_SESSION['CREATED'] = time();
    } else if (time() - $_SESSION['CREATED'] > $time_out) 
    {
        // sessão começou a mais de $time_out atrás
        session_regenerate_id(true);    // muda o ID de sessão para a atual sessão e invalida o antigo ID de sessão
        $_SESSION['CREATED'] = time();  // atualiza altura que a sessão foi criada
    }
}

Based in this answer of SOEN.

Try going there in the codeigniter application config.php and changing these values

$config['sess_expiration']= 0; /* nunca expirar a sessão sózinha  */
$config['sess_expire_on_close'] = TRUE; /* finalizar sessão quando o navegador for fechado */

or you can try for . htaccess

php_value session.cookie_lifetime "99999999"

Man, I’m tired of having trouble with the Codeigniter library Session. That’s why I developed mine based on PHP’s Native Session and never had a problem.

I opened a project on Github, follow the link: https://github.com/alamops/codeigniter_native_session
