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.
