Hey John:

If you still don't understand the problem, then take this quiz:
what is the output of the following statements?
var_dump(true + true);
var_dump(null < 0);
var_dump(null < -1);
var_dump(null < 1);
The third one tripped me up. It's TRUE. I expected it to be false under
the assumption that null == 0 in most PHP contexts. But it seems like
it's really nothing/null in this context.
Since null is nothing and a
negative number is something, it makes some sort of sense.
^^^^^^^^^^^^^^^ gotta love that commitment to PHP!
