Carl, setcookie returns boolean, so it would be prudent to check
whether it has actually happened. You should add something like:
if (!$result) { die("Better luck next time"); }
Second, cookies will NOT be sent if the HTML headers have already been
sent. Your heading (<html>) makes sure that they have been sent, so your
cookie will probably not be sent. You should do something like
<?php ob_start(); ?> before the HTML header.
