How can I determine if a URL redirects in PHP?

I saw someone ask a question about detecting if a URL redirects from groovy and perl but couldn\'t find anything on PHP.

Anyone know of somewhere I could find that c

Actually, I found this works best:

    function GetURL($URL)
    {
            $ch = curl_init($URL);

            curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);


            curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

            curl_exec($ch);

            $code = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

            curl_close($ch);

            return $code;
    }
