[PHP] cool OOP-phenomena!

[Moritz Petersen]

Hi list,

this is not a problem, but a nice feature of OOP, I found today. Maybe it is
useful for someone:

<?php
        // class test

        class Basis
        {
                var $name = "Basis";

                function Basis($typ = false)
                {
                        switch ($typ)
                        {
                                case "A":
                                        $this = new Basis_A();
                                        break;

                                case "B":
                                        $this = new Basis_B();
                                        break;
                        }
                }

                function print_name()
                {
                        echo $this->name . "<br>";
                }
        }

        class Basis_A extends Basis
        {
                var $name = "Basis_A";
        }

        class Basis_B extends Basis
        {
                var $name = "Basis_B";
        }

        $my_basis_1 = new Basis();
        $my_basis_2 = new Basis("A");
        $my_basis_3 = new Basis("B");

        $my_basis_1->print_name();
        $my_basis_2->print_name();
        $my_basis_3->print_name();
?>

The point is, that the class morphs itself into another class in the
constructor.

Hope it helps someone,

Moritz.
