challenge2.php

function super_sum($A){
$sum = 0;
        foreach ($A as $key => $value){
                //$sum += $value;
                do {
                    $sum += $value % 10;
                } while ($value = (int) $value / 10);
        }
        return $sum;
}
$A = [120, 13, 45];
print_r(super_sum($A));

Will this code sum up the digits really? i.e. 1 + 2 + 0 + 1 + 3 + 4 + 5 for $A = [120, 13, 34]?

Hi Nandaa,
I think understood it all wrong. I thought it was adding individual values in array. Let me update it right now, now that I understand it better.
