session_destroy() after certain amount of time in PHP

Question

I am currently saving a session in my form page:

$testingvalue = "SESSION TEST";

$_SESSION[\'testing\'] = $testingvalue;

Answer 1

you need a static start time to expire. $session_life > $inactive will always be greater no matter what.

session_start();

$testingvalue = "SESSION TEST";
$_SESSION['testing'] = $testingvalue;

// 2 hours in seconds
$inactive = 7200;


$_SESSION['expire'] = time() + $inactive; // static expire


if(time() > $_SESSION['expire'])
{  
$_SESSION['testing'] = '';
 session_unset();
 session_destroy(); 
$_SESSION['testing'] = '2 hours expired'; // test message
}

echo $_SESSION['testing'];
