My PHP solution to Project Euler problem # 1 http://projecteuler.net/problem=1 If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.

<?php
$sum = 0;
for ($i = 0; $i < 1000; $i++) {
if (!($i % 3) || !($i % 5)) {
$sum += $i;
}
}
echo $sum;
?>
