default to something like home.php.

I've been playing with something like this a little. I have an some other questions:

What if I want to return a 404 instead? How do I raise a 404 response error in PHP?

More specifically, I've got a bit of code like this: 

<? 

if (file_exists($f)) {

    output_header();

    include($f);

    output_footer();

}

else {

    header('HTTP/1.0 404 Not Found');

}


...which works, but I'd like to raise the 404 error in such a way that Apache serves my ErrorDocument. Is this possible?

Oh, and a security question: currently, this allows access outside the webserver's directories (you can use /index.php?f=/etc/passwd for example). Any good tips on avoiding this kind of problem?
