Which is only one reason this is a bad way of doing it.  But these were 
questions to point out problems with this method.

BTW - to delete files, you use unlink().  See the documentation at 
www.php.net - it's the best reference around.

Forget most of the web-based references.  There's a lot more crap out 
there than there is good stuff.  The best reference is the doc at 
www.php.net, as I said above.  Other than that, I would highly suggest 
you visit your local book store.  At least books have been through an 
editorial process, and in general are better.  Sorry I don't have any 
specific ones to suggest; it's been a while since I've looked.

Normally I also suggest your public library - but if it's like the one 
we have, the books will be several years old and way out of date for PHP.
