$output = curl_exec($ch); 
echo $last_url;
curl_close($ch); 


?>

but i am unable to get redirected url ,, please help me

Answer 1

You're trying to get the URL before starting the request. Try moving the $last_url= curl_getinfo($ch,CURLINFO_EFFECTIVE_URL); line to after the curl_exec($ch); call.

Answer 2

use $_SERVER['HTTP_REFERER']; to get last url. I use this only.
