Pls verify my process

I’m building a PHP based CMS. However, the gallery will run under flash.
Update/create/delete of the sections and images in the gallery will all be done in PHP and MYSQL.

I found this tutorial,

http://www.kirupa.com/developer/actionscript/flash_php_mysql.htm

and I’m actually planning to use PHP to print a XML formatted string for flash to process.

I’ve no experience working with flash and XML, so gotta ask if this is the correct way of doing things.

BTW, are there tutorials for integrating PHP with Flash using AS3.0 instead?
