How's this?

<?php
$divisor = 7;
if ($number >= $divisor)
	y();
if ($number % $divisor)
	$somevar = x() + z();
else
	x();
?>

I wasn't too sure about this that you wrote:

> if the number is say greater that a multiple (Say 25)

Isn't (any number modulo x) != 0 greater than a multiple of x?
(Mathematically speaking, there exists an infinite number of numbers
greater than "a multiple of x")

HTH,
David
