Flash / PHP Anti-Theft Systen

I know the standard response for questions on "how do i stop people from stealing my site things" is " if you dont want it stolen, dont put it online" .... i know that.

I was just wanting to make something that could be possibly useful to me and others in the future, its probably been done before, but i couldnt find anything on it in a couple of searches.

So, now that iv explained my motives...

I was thinking, if you could get a flash file to read the 'PHP_SELF' variable... (thats: ) you could then set what 'PHP_SELF' should be, and if not, dont play.

So, i have 3 questions:

Will it work?
How do you get flash to get the 'PHP_SELF' self variable?
And will you help me?


Any help would be great!
Thanks in advance.
