Question

I’m using file_get_contents() to grab content from a site, and amazingly it works even if the URL I pass as argument redirects to another URL.

The problem is I need to know the new URL, is there a way to do that?

Answer 1

You might make a request with cURL instead of file_get_contents().

Something like this should work…

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$a = curl_exec($ch);
if(preg_match('#Location: (.*)#', $a, $r))
 $l = trim($r[1]);
