Topic awaiting preservation: Deleting Session Cookie

How to delete a cookie set by session() function after a user hits logout or choose to end his session.

If the session is closed, the session variables die an horrible death.

If the user logs out, you're supposed to direct him/her to a log out page where you session_unset( ).

I tried doing session_unset() but its not deleting the cookie set by the session_start() and I want to delete the cookie whenever a user logs out

cookies and sessions variables are 2 different things.
If you want to delete a cookie, set it with an expiration date in the past like that :

setcookie( "TestCookie", "", time()-3600 );

whenever u start a session a cookie PHPSESSID is set to ur browser.NOw the problem I am facing is:
Whenever I try to login when this cookie is set in the browser I am unable to start a session, and if I delete this cookie using Firefox and then try to login a new session is created and the cookie PHPSESSID is set again in the browser.I am using Windows 2K,IIS,MSSQL and PHP.I tried deleting this cookie by
setcookie("PHPSESSID","") ;
as written in the PHP5 Bible but unable to delete this cookie using this function.

the sessions variables are assigned to a Session Id, which id is stored in a cookie so that the client "remember" it and can pass it to the server to retrieve its session variables.

Have you tried to delete it with :

setcookie( session_name() ,"",0,"/" );

Thanks for the help,It worked out.
Will come back shortly with another querry.
