You could also just use:
if (($i % 15) === 0) echo "FooBar";
elseif (($i % 3) === 0) echo "Foo";
elseif (($i % 5) === 0) echo "Bar";
15 works because 3 and 5 are mutually prime or whatever it's called.
The order matters, though, as moving the 15 "after" the other if tests
would fail, as 3 and/or 5 would kick in first.
It's also a "game" played in grade school when learning "clock
arithmetic" (aka the modulus operator) at least here in the Midwest,
usually around 4th grade (age 10), as I recall.
Each person in turn says the next number or "Fizz" or "Buzz" or
"FizzZBuzz", and if somebody messes up, you razz them for it, and
start over at 1.
The person who makes the mistake could also be "out" in a musical
chairs sort of thing, though that risks boredom creeping in for a
large group of people no longer actively playing. You do not want a
roomful of bored 4th-graders. Trust me on that one. :-)
If the numbers are not mutually prime, you would have to do an && test
as Stut posted.
A minimalist might not even bother with the 15 and would skip the
'else' and just do:
if (($i % 3) === 0) echo "Foo";
if (($i % 5) === 0) echo "Bar";
echo "\n";
I personally think that's less comprehensible, however, and less
maintainable, so I'd rather see a couple more CPU cycles than have
code I have to think about to figure out what it does, until it's a
proven bottleneck.
YMMV

Some people have a "gift" link here.
Know what I want?
I want you to buy a CD from some starving artist.

Yeah, I get a buck. So?
