session_destroy on browser closing

twcmad

I am looking for a way to call a session_unset() and then Session_destory () when a client exits the browser while still being looged in.

I have the facility to "log out" an a page which is fine if the client uses this. But if they simply close the browser the sessions remain. I am having to delete all the sessions from the server manually.

I have tried

This then opens a simple page which unsets the sessions then destorys them. How ever I cannot find a way for this to close by itself.

Any ideas ?

Or is the lifetime of a session determined in the php.ini file ?

the lifetime of the session is set in the PHP.ini file, have alook

; Lifetime in seconds of cookie or, if 0, until browser is restarted.
session.cookie_lifetime=0
