I am trying to use javascript to call a php script which then will return multiple variables back to my javascript so I can manipulate them.

This is my JS.

                $.ajax({ 

                    url: 'test.php',

                    data: { id : lastFileId },

                    success: function(output) {

                        alert(output);

                    }

                });

my PHP

<?php

    $fileId = ($_GET['id']);

    $num1 = 1;

    $num2 = 2;



?>

From here, how can I return variables $num1 and $num2 so i can use them in my javascript. Is it possible?

also this is a very basic idea of what I have planned to do if I can achieve this.
