I wonder why you switched from "when the remainder is zero" to "when not the remainder". (Reminds me of the baby in Dinosaurs: "Not the Momma! Not the Momma!")

Update: Nevermind, I guess it can be read "when no remainder". I guess I don't think of a remainder of zero as there being no remainder, so it looks weird to me.

    The modulo construct can also be thought of as 'divisible by' -- so $foo % 3 checks to see if $foo is divisible by 3. Or at least that's the way my brain works.

      That's backwards. $foo % 3 checks if $foo *isn't* divisible by 3. not $foo % 3 would deceptively check if is divisible by 3.

        OK, OK. :) And in this tiny corner of the universe, I'm pretending that a result of 0 means "Yes! It's divisible!". :)

        Your confusion was not my intention.
