and when i manually posted the data it will get the response But when I am using curl to post the url which i have posted previous it will face the error.
My curl code is :-

$header[] = "Accept: application/json";
$header[] = "Accept-Encoding: gzip";
$header[] = "Content-length: 0";
$ch = curl_init();

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_ENCODING, "gzip");
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_VERBOSE, true);
$verbose = fopen('php://temp', 'rw+');
curl_setopt($ch, CURLOPT_STDERR, $verbose);

$result = curl_exec($ch);

After posting data i will get the response

{"HotelRoomReservationResponse":{"EanWsError":{"itineraryId":-1,"handling":"UNRECOVERABLE","category":"EXCEPTION","exceptionConditionId":-1,"presentationMessage":"TravelNow.com cannot service this request.","verboseMessage":"Exception Caught: null"},"customerSessionId":"8ab1d482-f968-49d2-a429-a1cbab748fe5"}}

So i will get that error repeatedly. Please help me how i can find the right data.
