Rather use a cookie.

Create the cookie with an expiry date 4 hours in the future. Send that cookie to the browser

When a user connects - check the cookie - if it exists - all is good - refresh the expiry to 4 hours in the future.

No cookie - then the session has expired.
setcookie()

<?php
// SECURE PAGE
if (isset($_COOKIE['YOURSESSIONNAME'])) {
   // Session is still active
   // REFRESH IT
   setcookie('YOURSESSIONNAME', 'value you want to store', time() + 14400);
}
else {
   // SESSION EXPIRED SO BOUNCE TO THE LOGIN PAGE
   header('location: login.php');
}

Open in new window

// CHANGE TO MATCH YOUR AUTHENTICATION PROCESS
if (Login($username, $password)) {
  setcookie('YOURSESSIONNAME', 'value you want to store', time() + 14400);
}
