Additionally you could do:
$file = $_SERVER['PHP_SELF'];
Which will tie the filename to the actual PHP file.
But you might want to do something like...
$file = urlencode($_SERVER['REQUEST_URI']).".txt";
to make it the full url, safe vars for file names and add .txt to make it readable in other things not FreeBSD.
