In PHP, how do I map arrays with strong typing?

In PHP, you can map arrays with strong typing using the `array_map()` function along with type declarations. This allows you to define the expected types for the callback function and its parameters, making your code more robust and easier to maintain.

This example demonstrates how to map an array of integers to their squares using strong typing in PHP.


        <?php
        function square(int $number): int {
            return $number * $number;
        }

        $numbers = [1, 2, 3, 4, 5];
        $squaredNumbers = array_map('square', $numbers);

        print_r($squaredNumbers);
        ?>
