Check for Session End

[mj_23]

I'm currently using setcookie() function to store session variables eg.
setcookie($session_user,"abc");

how do I check if the session has ended (either by *closing browser, timeout or setcookie($session_user,"")😉?

I need it for my shopping cart so that when the user ends the session, the shopping cart will be deleted straight away.

Thanks in advance.

There is only one way of knowing when a user has stopped browsing your site, and that is by timeout.
If a user has not requested anything from your site in 20 minutes or so, it's safe to say that he/she has stopped browsing your site.

Sessions have a timeout value that you can set in php.ini.
If the session has expired, it will be deleted at the next garbage-cleanup

how do i make my server execute a script to clean up the shopping cart of the user when his session has timed out?

It depends, how do your store the shoppingcart itself?

It's stored in a mysql table created using the session_id of the user
