Live message board

im wondering if anyone has any ideas on how to create a live message board in flash php and mysql databases

what i want to do is for users to be abel to post messages in forum style , with title message and so on , and for them to be listed out on a page ( not more complicated than that, no different topics or anything)
and i want flash to check if there are any new posts ever like 10 seconds

anyone have any tutorials or suggestions?


(im pretty fluent in all three languages, AS, PhP and MySql)
