SWX: SWF Data Format

Create a new file using your text editor of choice under php/services/ and call it Calculator.php.

Add the following code to Calculator.php and save the file:

<?php
    class Calculator
    {
        function addNumbers($n1, $n2)
        {
            return $n1 + $n2;
        }
    }
?>

This is a very simple server-side service class that has a single method called addNumbers(). This method takes two numbers as arguments and returns their sum.

At this point, it would be nice if you could test the server-side method you just created without having to create a Flash client. SWX Service Explorer lets you do just that.
