Yes, but that's because of the way you wrote it -- consider this:

I'm sure that was completely intentional.

<?php
switch( $foo )
{
case 0:
// something
break;

case 2:
case 3:
// something else
// something elser
break;

default:
// something defaulty
}
?>

If you group the case's together, then there's no problem understanding what happens in case 2 or 3.

What happens if (like in Rob's example) I want a bunch of extra stuff to happen for case 2 but not 3?

You can either group them like you have and have:

case 2:
case 3:
if ($foo == 2) {
// do extra stuff
}
....
break;

or not put them under each other:

case 2:
// do extra stuff

case 3:
....
break;
