Return to the SWX Service Explorer (or open it if you didn't earlier) and you will see the Calculator class you just created. Click on it and you will see the addNumbers() method. Enter two numbers in the $n1 and $n2 fields and press the call button to test out the method. You should see the sum returned in the results area.

SWX is so simple that instructions for getting data into Flash using it easily fit on to a Moo card (ask me for one if you see me around!)
To get a list of the most recent 100 photos from Flickr into Flash, do the following:
- Open up the SWX Data Analyzer
- In Flash, create a new FLA and create a movie clip on the Stage. Give it the instance name
loader. - Write the following code on to the frame that the
loadermovie clip is on:
loader.serviceClass = "Flickr"; loader.method = "swxPhotosGetRecent"; loader.debug = true; loader.loadMovie("http://swxformat.org/php/swx.php", "GET");
That’s it! Test your movie and look in the SWX Data Analyzer to see the results being loaded in to Flash from Flickr. That’s how simple SWX is.
If you want to display the results from within Flash, create a long, single-line dynamic text field on stage and give it the instance name status. Add the following code to the timeline:
function onEnterFrame() { status.text = loader.result.photo[0].src; }
Initially, the status text field will display undefined until the data is loaded and then it will display the URL of the first photo from the list of recent photos that is loaded from Flickr. Notice how you can access the results as native Flash objects the moment they’re loaded. No deserialization or massaging of the data is necessary!
In this example, you used the SWX Public Gateway (http://swxformat.org/php/swx.php) which you're welcome to use in your own applications to create mashups with the supported APIs (Flickr, Twitter, etc.) without having to host or write any back-end code yourself.
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.
To start you off, you're going to build a simple, but complete web application with SWX PHP. You are going to create both the client side and the server side of the application. By the end of this tutorial, you should have a clear conceptual understanding of how SWX PHP works.
The application you're building is a simple calculator that uses a server-side method to add two numbers together.
To start, you're going to create a PHP service class. In SWX you place service classes under the php/services folder.
