ROFL @ myself.

anyway, to expand this even further. if you modify the listFiles function as
i described, you can search for multiple files in a dir at one time and know
which WERE and were NOT found...like this:

$find = array('index.php', 'some.file.txt');
$found = listFiles($path, $find);
$missing = array_diff($find, $files);

that's the beauty of writing re-usable functions that are limited to single
tasks. it make building on or from them very easily done.

cheers
