to destroy the session you can use
session_destroy()
(that destroys all sessions)

or set the Session value to null
$_SESSION["mysession"] = "";

and by closing the window, the session is normally killded off anyway

[chiprivers]

I think if you use

session_set_cookie_params(x);

x is the number of seconds until the cookie that holds the session id will be destroyed. If you do not declare x, and just use

session_set_cookie_params();

the cookie will be destroyed whent he browser window is closed.

How I track the window is closeing to call session_destroy(); I am opening a window and right click on a link and open a child window. The session is start on chid window. After closing the child window when i open a new child window find the session is still running. How i destroy the session when i close the child window.

Thanks in advance

if the window is closed, the session will be destroyed automaticly

Many people have been asking about tracking when someone closes a window, for member areas, to log people out,
But as far as I know, it can not be done

The session does not close automaticaly. Any other solution?
