Correction: include() statements are executed at *run time*, which means
that if the case is not executed, the include will not be executed and
the file is not even read! The include() method is not only more
efficient but also easier to maintain as you suggest.
Otherwise, I'm curious as to why you're using a large switch, not that
it's bad inherently IMHO, but there may be a better overall approach.
