When I call setcookie(cookiename, ""), firefox does not destroy the cookie. IE does. Is this a browser thing or is there something I can do with php or javascript to force the cookie to delete instantly? Thanks!
Firefox never failed me in removing cookies. Are you sure you are doing the right thing? What version is your firefox?
firefox 2.0.0.13 To set the cookies: setcookie ("USERNAME", $_POST['username'], $expires, '/'); // $expires is either 0 or 10 years from time() To delete them: setcookie ("USERNAME", "", time() - 3600); // same code as in the php.net manual
