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.
