Method Overloading

Two or more methods have the same name but different parameters are called Method overloading.

Syntax:

 class A 
{   
		void show(int a)
        {
         //body of the method. 
        }
        void show(int a, int b)
        {
         //body of the method. 
        } 
}
PHP Function Overloading

Example:

 <?php
class A {
    public function show() {
        $args = func_get_args();
        $count = func_num_args();

        if ($count == 1) {
            echo "Area of square: " . ($args[0] * $args[0]) . "\n";
        } elseif ($count == 2) {
            echo "Area of Rectangle: " . ($args[0] * $args[1]) . "\n";
        } else {
            echo "Invalid number of arguments\n";
        }
    }
}

$a = new A();
$a->show(5);
$a->show(5, 7);
?>
