Curl, follow location but only get header of the new location?

Question

I know that when I set CURLOPT_FOLLOWLOCATION to true, cURL will follow the Location header and redirect to new page. But is it possible only to get header of the new page w

Answer 1

Yes, you can set it to follow the redirect until you get the last location on the header response.

The function to get the last redirect:

function get_redirect_final_target($url)
{
    $ch = curl_init($url);        
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // follow redirects
    curl_setopt($ch, CURLOPT_AUTOREFERER, 1); // set referer on redirect
    curl_setopt($ch,CURLOPT_HEADER,false); // if you want to print the header response change false to true
    $response = curl_exec($ch);
    $target = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
    curl_close($ch);
    if ($target)
        return $target; // the location you want
    return false;
}
