Good point, missed that one.

Except that you're not displaying the actual number when it's not divisible between 3 or 5, so that doesn't meet the spec.

Re: [PHP] help with script needed
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

This is what I have come up with

for( $i=1; $i=100; $i++ )
{
echo $i;
echo br;
if ($i%3 == 0) echo Foo ;
elseif ($i%5 == 0) echo Bar;
}
?
[/php]
and the results can be seen here
http://www.inspired-evolution.com/image_test/numbers_output.php
I actually want the Foo and Bar to replace the numbers they are
dereivatives of and not appear below as they are now, and I also need
to add a third condition for FooBar which would be for numbers that
are both divisible by 3 and 5.
thanks

if( intval($number / $multiple) == ($number / $multiple ) )
try that
Very bad solution. Try the % operator:
if($number % $multiple == 0)

Ok, this is commonly known as the FizzBuzz problem and is used a lot as
a university project or interview question. If you can't do it, be afraid!!
http://dev.stut.net/php/fizzbuzz.php
$upto = 100;
$cur = 1;
for ($cur = 1; $cur = $upto; $cur++) {
if ($cur % 3 == 0) {
print 'Fizz';
if ($cur % 5 == 0) print 'Buzz';
} else if ($cur % 5 == 0) {
print 'Buzz';
} else {
print $cur;
}
print br /;
}
no need to do each modulo twice per iteration :-)

Re: [PHP] help with script needed
Are you only using 3 and 5? just echo 3 and 5 instead of Foo and Bar. and
for both, just have a 3rd condition including both ... if (($i%3 ==0)
($i%5 == 0)) echo both or foobar..
does this help?
