I don't understand how this could much improve things, though I do
understand that in some technical sense it is better syntax for the
test I want to do. Perhaps I'll try it when I've spare time today.
However, you miss the main thing I'm curious about: as a function in
procedural code, this function works well and has never failed me. Now
that I'm trying to make it the method of an object, it has stopped
working. I'm looking for something that is specific to the object that
would cause it not to work. I've already checked what I thought was
obvious: do the variables have scope here, am I using the "$this->"
syntax. It seems I've done all that, yet the code won't work, and, as
I say, it works well as a function outside of this class.
For now, I've gone back to using getVar, the function, rather than
$io->getVar, the class method. But as I'm moving to OO, I'd like to
figure out how to make this function work as a class method.

You always have to check, if a variable has a value at all and then,
if the value is within range of the values you expect.
However, you miss the main thing I'm curious about: as a function in

I only see you using $HTTP_POST_VARS witthout global. You can only do
that with $_POST, which is superglobal. MAybe thats the problem.

What is a superglobal?

A variable which is available in all functions and outside as well.
