Just a quick thought. You're not trying to read in the value of the
cookie in the same page as you are setting it are you? You can do this
with session variables, but not cookies, as PHP only reads them if they
are sent in with the page request headers. So if you set a cookie, it
won't be visible to your script until the page is refreshed, which
forces the browser to resend the cookies, including the newly set cookie
value.
