Find multiples of a number in PHP

I want to find all muliples of a number in PHP.

I'm using something like this

if($count != 20 )

to work out if $count is not equal to 20.

But I also need this script to check if $count is not equal to 20, 40, 60, 80, 100, 120, 140, 160 etc.

Any ideas? I think i need to use the modulus symbol (%), but I don't know.

If you don't want zero to be excluded:

if ($count % 20 != 0 || $count == 0)

if ($count % 20 != 0)
{
  // $count is not a multiple of 20
}
