What are alternatives to objects and how do they compare?

    // Example of using functional programming as an alternative to an object-oriented approach
    function add($a, $b) {
        return $a + $b;
    }

    function processArray($array) {
        return array_map('add', $array, array_fill(0, count($array), 1));
    }

    $numbers = [1, 2, 3];
    $result = processArray($numbers);
    print_r($result); // Outputs: Array ( [0] => 2 [1] => 3 [2] => 4 )
