What are alternatives to polymorphism and how do they compare?

    // Example of Method Overloading in PHP (Function Overloading)
    class MathOperations {
        public function add($a, $b) {
            return $a + $b;
        }

        // The method name is the same, but the number of parameters differ
        public function add($a, $b, $c) {
            return $a + $b + $c;
        }
    }

    $math = new MathOperations();
    echo $math->add(2, 3); // Will output an error due to method overloading not being natively supported
    // PHP does not support traditional method overloading, but can use arguments to achieve similar functionality.
