Oh, well, fair enough -- I can live with that, although I think it's a less
elegant way of programming it.  Still, nothing ventured nothing gained...!

Cheers!

Mike, changing this would break all sorts of stuff, and I think it would
confuse a lot of people.  If HTML form variables were somehow typed by the
browsers, then it might make sense, but people are going to write code
like:

  switch($input) {
    case 1:
      ...
    case 2:
      ...
    case 3:
      ...
  }

Forcing people to worry about the type on user input goes against the
basic nature of PHP.
