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

Something like this should work

 $inactive)) {
    // last request was more than 2 hours ago
    session_unset();     // unset $_SESSION variable for this page
    session_destroy();   // destroy session data
}
$_SESSION['testing'] = time(); // Update session
