Hi Brandy - I'm in the process of converting my current PHP-HTML site into a PHP/Flash site. It's pretty easy to start off.
What you need is to do is get PHP to output a very simple file with all the variables and their contents (so that Flash can read them) in the format: text="content blah blah blah blah"
With or without the quotes, and use \r\n to create newlines and use & to separate variables in the file. Flash then reads the data into the variables in its movie, which could be a text box with the name text, or anything. The data could be a link which a button calls.
If you want some sample stuff, drop me an email and I'll email you a ZIP file of stuff.
Regards,
Vish
