$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Must be set to true so that PHP follows any "Location:" header
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$a = curl_exec($ch); // $a will contain all headers

$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL); // This is what you need, it will return you the last effective URL

// Uncomment to see all headers
/*
echo "<pre>";
print_r($a);echo"<br>";
echo "</pre>";
*/

echo $url; // Voila
?>

The simplest way to create a 301 redirect with php is by using the php's header() function. Here is an example of how to use this function:

// Redirect to the specified page
header('HTTP/1.1 301 Moved Permanently');
header('Location: http://www.example.com');

// Stop script execution
exit();
