I\'m fairly new to PHP and am looking for some best practices on how to implement authentication in PHP.

That's a fairly broad topic. However, a good understanding of sessions/cookies would be a good base. You should take a look at Chris Shiflett's blog - he has a lot of good posts about these topics.
I'm an evangelist for Adobe and one of the things that annoys me is when people use Flex/Flash for the login screen. So I want to do a blog post/example on using an HTML/PHP login page and then passing the session information to Flex -after- the session has been set.
I'm not entirely sure on your goal here. Do you need the Flash component to authenticate the user? Since this is a client-side technology, such an authentication would have limited scope.
