In PHP, how do I map arrays for beginners?

In PHP, you can map arrays using the array_map() function. This function applies a callback to the elements of the given arrays and returns an array containing the results. It's a great way to transform data without needing to write explicit loops!


            <?php
            // Define an array of numbers
            $numbers = [1, 2, 3, 4, 5];

            // Function to double the value
            function double($n) {
                return $n * 2;
            }

            // Use array_map to apply the double function
            $doubledNumbers = array_map("double", $numbers);

            // Output the result
            print_r($doubledNumbers);
            ?>
