Destroying Cookie + IE

[roadshow]

I'm using the login script from here. Logging out in firefox works fine. In IE, it doesn't log you out, however. It says "logged in as gone" and you have to manually delete all cookies in the browser.

 

Here's the log out code:

 

<?php
$past = time() - 100;
//this makes the time in the past to destroy the cookie
setcookie(ID_my_site, gone, $past);
setcookie(Key_my_site, gone, $past);
header("Location: login.php");
?>

 

IE reads that "gone" as a user. It doesn't work in any browser if the gone is removed.

 

Any ideas?

Try putting quotes around "gone"

 

setcookie(ID_my_site, 'gone', $past);
setcookie(Key_my_site, 'gone', $past);

setcookie("ID_my_site", "gone", $past);

Hmm. It's still doing it.

1) It's up to the browser of how and when to delete the cookie. You can't control it from PHP (especially with IE). IE tends to delete cookies when the browser is closed and not right after a setcookie() is invoked.

2) The time in the past should be set back at least a day or more and not just 300 seconds. You're assuming the time on the client machine is the same as your server. Their clock could be set to anything (in which case the cookie may not get deleted).

3) You're not showing us all your code of how you're using the cookie. In any case, I would suggest you use PHP sessions rather than just relying on cookies alone.
