How can one efficiently store the results of multiplying two arrays in PHP?

When multiplying two arrays in PHP, you can efficiently store the results by using the array_map() function. This function applies a callback function to each element of the arrays and returns a new array with the results. By using array_map() with a multiplication function as the callback, you can easily store the multiplied results in a new array. 

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

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

print_r($result);
