Tutorial idea: PHP XML SQL?

Well someone had a question about PHP and XML going into Flash in this thread:


I posted about how to make PHP output its content as XML, but there is much more that is possible with it. I was thinking about writing up a tutorial for taking your SQL data from the database and using a PHP script to output it as XML for easy manipulation inside of a Flash file (ie: blog, guestbook, shoutbox, etc…) I wanted to run it by everyone before I started just make sure you think it would be a good idea… what do you think?
