Are you sure you don't have more than one db.php on your system?
hello.php is finding a script (or the require_once() would have failed),
but it may or may not be the right one.
I always recommend any include/require statements use paths relative to
$_SERVER['DOCUMENT_ROOT']. That way if files the including file gets
moved to another directory it still gets the correct file.
