cannot expire cookie

[steve]

Hi,
I am having problems expiring cookies in PHP, i.e. when you want to
logout of an application.

Has anyone had this problem, and what is the solution. Working code is
appreciated.

Show us your code, maybe we can pinpoint the problem.

FUP: comp.lang.php

sorry I should have provided code:

setcookie("user", "", mktime(12,0,0,1, 1, 1990), "/");

Just set a new cookie with the same name when they "log out" and set an
expired time on the cookie. Either that or set no time on it and have
it expire when they close the window or leave the page.

The code above should clear the "user" cookie, but only
if it was set with path parameter "/" and with time
set (AFAIK session cookies - set with zero time - cannot
be forced to expire, but can be cleared; you have to
provide zero as time in clearing command).

Remember that setting cookies (or clearing them) does not
mean that you'll see the changes in the script in which
you changed the cookie (you need reload or something).
