Updateable news:which tutorial?

I want to make a page/movie on my flash site that has an updateable news section. I’m new to scripting and want to know what is best. i’ve found loads of tutorials using different server side technology but don’t know what to use.

I think that PHP, MY SQL and XML will be most useful in the long term. I’ve looked at the sticky on the server side forum but some aren’t very well written and don’t want to waste my time. If anyone can help me out with a tutorial they have found helpful it would be appreciated.:ne:
