Hey.

Try the onbeforeunload event.

hi
would you please descibe with more details

You could use the onbeforeunload event to execute an AJAX request for a PHP file that would clear whatever sessions stuff you want cleared.

For example, using jQuery for the AJAX stuff:

index.html

window.onbeforeunload = function()  {
    $.get('clear_session.php');
    return 'The sessions have been cleared!';
}

clear_session.php

<?php
session_start();
session_destroy();
?>

This would bring up a prompt when the window or tab is closed, asking if the user really wants to close it. Meanwhile, the AJAX request is sent and the PHP code executed, clearing the session.
