 $options["http"]["method"] = $method;
 $options["http"]["user_agent"] = $_SERVER["HTTP_USER_AGENT"];
 $options["http"]["timeout"] = $timeout;
 if($method == "POST") :
  $length = strlen($data);
  $options["http"]["header"] = "Content-type: application/x-www-form-urlencoded".
  "Content-Length: {$length}".
