Can't parse $http.post data

hi Ionics,
i have some difficulties to parse the $http.post() data via php.
this is my angularjs part :
var postUrl = ‘http://my_url’;
var data = {“lat”: location.latitude, “lng”: location.longitude, “user_id”: 3};
var config = {
headers : {‘Content-Type’:‘application/x-www-form-urlencoded; charset=UTF-8’},
cache: false
};

              $http.post(postUrl, data, config)
                  .success(function (data, status, headers, config)
                      $scope.status = status;
                      $scope.data = data;
              }).error(function (err) {
                  $scope.data = "Request failed";
                  $scope.status = status;
              });

my php (parser) code ;

           //file_get_contents only works when allow_url_fopen
           ini_set("allow_url_fopen", true);

	$data = file_get_contents("php://input");
	$postData = json_decode($data);

thanks for help

Maybe this can help you… for me it worked

thanks! fixed.

angular :
var config = {
headers : {‘Content-Type’:‘application/x-www-form-urlencoded; charset=UTF-8’},
cache: false,
};

php :

$data = json_decode(file_get_contents(‘php://input’));
