//print_r($ss);
// exit;
$response = curl_exec($ch);
print_r($response);
exit;
curl_close($ch);
?>
I got only Empty response only please give me any idea highly appreciated.

Answer 1

I would start by adding:
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
That will allow you to see the response http code of the server.
Usually when I work on SOAP / REST services I make sure to have Fiddler running in the background, that makes debugging a lot easier.
You can find how to use Fiddler with cURL here: Configure PHP cURL
