Major weirdness, sudden 404 with no changes.

Careful with the ctype_digit(). It only works if you pass in a string. Because of the way php handles variables it might already be an int. I can't test it right now, but try doing $id = settype($id, "int");

EDIT: Actually, your best bet would probably be is_numeric($id)
