Don’t use loop do instead function

Improve code readability with PHP’s array_map() function. Instead of looping through items to change them, apply a callback to each element in one go.

$numbers = [1, 2, 3, 4, 5];

// Apply a function to each element of the array
$squaredNumber = array_map(function ($number) {
    return number * number;
}, $numbers);

// Output: 1, 4, 9, 16, 25

The array_map function will iterate through the $numbers as $number. So $number will have each index value of $numbers.
