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.

Answer 1

Use a simply string and explode(split) it further in ajax response. Here is PHP code

Now split(explode) the response with JavaScript

$.ajax({ 
        url: 'test.php',
        data: { id : lastFileId },
        success: function(output) {
             var my_arr = output.split("|");
             console.log(my_arr[0] + "" + my_arr[1]);
        }
});
