Best method for sum two arrays [closed]
a simple approach could be
$c = array_map(function () { return array_sum(func_get_args());}, $a, $b);print_r($c);Or if you could use PHP5.6, you could also use variadic functions like this
$c = array_map(function (...$arrays) { return array_sum($arrays);}, $a, $b);print_r($c);Output
Array( [0] => 11 [1] => 22 [2] => 16 [3] => 18 [4] => 3)
There's no way you can do that without the "foreach" as you asked for, you need to loop on both arrays to get the respective values.
A function using the foreach would be :
function sum_arrays($array1, $array2) { $array = array(); foreach($array1 as $index => $value) { $array[$index] = isset($array2[$index]) ? $array2[$index] + $value : $value; } return $array;}Now you just need to do :
$c = sum_arrays($a, $b);
