Sending the Data from Angularjs in the form of JSON as below
Object {data: "stdClass Object↵(↵ [0] => B↵ [vin] => vin123…[value] => Gambia↵ [country_name] => Gambia↵)↵", status: 200, headers: function, config: Object}
Then in php how to access only the data in that Object Json i.e data->0, data->vin etc...........
Simply use json_decode() as it is a standard PHP function that transforms your serialized JSON object into a php array, that you then can use in php.
If you want an object representation, you may hydrate that object with data from that array.
