In the example above you will get the headers in $result.
With curl_getinfo(CURLINFO_HEADER_SIZE) you can also check how long the
header part in $result is (beginning with the first character), so
$headers = substr($result, curl_getinfo(CURLINFO_HEADER_SIZE));
should give you all headers.
HTTP headers are in the form
Header1: Value
Header2: Value
[...]
And the redirection URL is
Location: URL
So try to find the "Location: " part and use the remaining text up to
the line break.
BTW: Using tools like the Firebug AddOn for Firefox help a lot to
understand HTTP headers.
