Code: Select all

<?php

$total = $oscost + $cpucost + $hddcost;

?>

If it's an array you're adding up then use array_sum().

Code: Select all

<?php

$array = array(1, 2, 4, 8, 16);

echo array_sum($array); //31

?>

I would assume it is numbers, because his variables have "cost" in it. I am not %100 positive though.
