JsonSerializable CODE
Serializes the object to a value that can be serialized natively by 
json_encode()
class MyClass implements JsonSerializable {
    public function jsonSerialize() {
        return json_encode([1, 2, "44"]);
    }
}
$c = new MyClass();
echo json_encode($c);
In this example after calling 
json_encode($c)
function, 
JsonSerializable
will be called automatically because the class 
MyClass
implements 
JsonSerializable
