Answer 1

You can set an expiration time for the session data, test it with each session_start call and destroy the session if it’s expired:

session_start(); if (!isset($_SESSION['EXPIRES']) || $_SESSION['EXPIRES'] < time()+3600) {     session_destroy();     $_SESSION = array(); } $_SESSION['EXPIRES'] = time() + 3600; 

Answer 2

You cannot. However, session cookies are usually sent without an expire time which means they are deleted when the browser is closed, so the session is lost anyway.
