ActionScript BEncoded XML file. Decoding same way as Flash:URLLoader in PHP

Hope topic is relevant :)

I have a class in Action script that loads and interpretes an XML File. What I want to do is to be able to decode this file using PHP (Probably some kind of Binary Decoding)

private static function interpreteXML(j:Event):void

    {

....... some var defined here.....

var event:Event = j;

var loader:URLLoader = (event.target as URLLoader);

try

  {

      xml = new cXML();

      xml.SetXMLString(String(loader.data));

   }

I'm looking for a function/class that would be able to decode XML in same way as URLLoader

From what I saw in Flash AS3 Docs, URLLoader have abbility to load Binary encoded data and decode it. That's why I look for a PHP version of this method to be able to interprete files on PHP level.
