What are some best practices for efficiently summing values from two arrays in PHP?

To efficiently sum values from two arrays in PHP, one common approach is to use the array_map function along with a custom function to add corresponding elements from both arrays. This allows for a concise and efficient way to sum values without the need for explicit loops. 

$array1 = [1, 2, 3, 4];
$array2 = [5, 6, 7, 8];

$result = array_map(function($a, $b) {
    return $a + $b;
}, $array1, $array2);

print_r($result);
