As of PHP 4.0.4 the function array_sum() exists (it's undocumented, but
in changelog), it's used as such :
$array = array(1,3,5);
$sum = array_sum($array);
Or loop through array as such :
foreach ($array as $value) {
$sum += $value;
}
Either way, $sum now equals 9. For info on how all the above works, see :
