First of all, a cookie won't be available in the $_COOKIES array until
the browser fetches the next page. It is not available on the page you
set it (unless you already had a cookie with that name stored).

And your second setcookie() call will always fail. You cannot set a
cookie after headers are sent, and ANY output to the browser causes the
headers to be sent. You will see this error if your php.ini file has:

error_reporting = E_ALL // or E_ALL | E_STRICT
display_errors = on

As a side, you are never using the $domain value. The cookie will
belong to the domain you are requesting the page from - if that happens
to be 'localhost', it will belong to localhost.
