Dynamically managing Flash content

Hello all.

I’m writing (in PHP) a content management system for a Flash-based website. The Flash movie draws its text from an XML file, so I decided to use SimpleXML to write a quick online editor.

But first, I wanted to ask how other people dynamically manage Flash content. Am I going about this the standard way, or is there a simpler, more common way to manage Flash content online? I am definitely not a Flash designer, I am a PHP coder, this is why I ask.

Thanks!
