I have a lot more trouble answering Angular questions on StackOverflow than I did answering Flex questions. The bulk of Angular problems seem to come from integrating different systems and libraries together. But, every once in a while I see a question that I seem to be the perfect person to answer. This question is about Sending JSON from Angular to PHP. I wrote a book about that.
When sending JSON to PHP--or Java or ColdFusion or any server side tech--you need to be sure to set the headers to application/json.
If you are using Angular 2, this is how you do it:
2optionHeaders.append('Content-Type', 'application/json');
3let options: RequestOptions = new RequestOptions({headers:optionHeaders});
4this.http.post(serverEndPoint, JSONPayload,options);
We create an instance of a RequestOptions object, and add the Headers onto it. The RequestOptions object is sent as part of your server request, in this case using a post() method. This is all part of the now deprecated Http library.
Angular 5 introduced the new HttpClient library, which does things a bit differently:
2let optionHeaders : HttpHeaders = new HttpHeaders().set('Content-Type', 'application/json');
3options = {headers:optionHeaders};
4this.http.post(serverEndPoint, JSONPayload,options);
You create a generic options object, and add an HttpHeaders() instance inside of it. Send that as the options argument to the http method, also a post().
