curl_exec() returns FALSE on failure. Check for it's success before echoing your $result . On failure, call curl_error() to see the most recent error message returned.

$result = curl_exec ($ch);
if ($result) {
  // Success.
  echo $result;
}
else {
  // something went wrong.
  echo curl_error($ch);
}
curl_close($ch);
exit();
