How to Protect your SWF (AS2 or AS3). Prevent SWF Decompile using SWF Protector

Being a flash programmer, I have always had this concern. The way a flash application works differs from a php application. We don’t really need to worry about protecting the PHP code because the code is interpreted in the server and only the html codes are sent to the client browser. But a Flash engine basically lies in the user browser and the AS2 or AS3 codes are rendered in the user Browser. Though a Flash application is compiled in to a compact SWF file which is served to the user, this file contains all the codes we have written, thus making it easy for hackers or other developers to steal codes from our SWF application. And the Actionscript code is the most important part of any Flash/Flex application.

Swap Values Without Temp or A Third Variable in PHP

When we need to swap the values of two variables, we use a third variable temporarily to hold the data between swapping.  Something like this:

<?php
$tmp = $a;
$a = $b;
$b = $tmp;
?>

Here is another way without using a temp or a third variable.

<?php
list($b, $a) = array($a, $b);
?>

And if you want to make it a function:
