Hi. I would advise you to work your way through a book about AngularJS so that you can understand this big topic well. The data format used in communication with a back-end is JSON format. As well as a REST API, you could use the $HTTP service which may be easier at first. Also, the POST data from Javascript is accessed in a special way with $data = json_decode(file_get_contents(“php://input”)); with PHP.
