Flex 3: mxml to swf

HI Everyone,

I have Flex 3 installed on my Windows XP System.

I have manged to compile an HelloWorld.mxml to HelloWorld.swf using the Flex Command Line Interface.

The Content of the mxml file is


<?xml version="1.0"?>
<Application xmlns="http://www.adobe.com/2006/mxml">
<Label text="Hello, world!" />
</Application>


I was able to do this using the following command

C:\Program Files\Adobe\Flex Builder 3>mxmlc c:\HelloWorld.mxml


The above command converted the mxml file to swf.

Now can someone please tell me how do I run this command using PHP?


Many Thanks in Advance
