PHP Expire cookie

Question

I am new to cookies and looking to make this cookie expire on my logout page

Here is where I set the cookie:

   setcookie("loggood", "YES", $expire, "/", "", 0);  
    setcookie("user", $pid, $expire, "/", "", 0);    

Can anyone help me with how to make a cookie expire so the user can logout?

Thanks

If you want to delete a cookie, then just set $expire time to be in the past:

setcookie("loggood", "", time() - 3600);
setcookie("user", "", time() - 3600);

Notes from PHP documentation :

When deleting a cookie you should assure that the expiration date is in the past, to trigger the removal mechanism in your browser.
