What is the best way to implement a scope function that will generate and return JSON data in Angular?

I have a function that looks like this:

 $scope.GetDays = function() {
         $http.post("core/ajax/LoadDays.php").success(function(data){
                 return data[0].days;
    }); 

};

Within LoadDays.php, the json is as follows:

 [{"days":"1"}]

When I console log it, the correct value of 1 is returned. However, I encounter a looping error ($rootScope:infdig) when I call it in my HTML code.

Any suggestions on how to resolve this issue?

Please excuse any language errors.

Take a moment to familiarize yourself with the idea of Ajax (asynchronous JavaScript) as it relates to what you're currently working on.

Consider implementing something along these lines:

$scope.LoadWeather = function() {
         $http.post("core/ajax/RetrieveWeather.php").success(function(data){
                 $scope.weather= data[0].forecast;
    }); 

};

Then, utilize {{weather}} in your HTML. The weather data will populate shortly after invoking LoadWeather(), depending on the speed at which the server processes the request.
