I want to execute polymorphism.

...BUT the OP didn't ask about polymorphism and php doesn't support it at all anyway. if you want polymorphism either use another language, drop the requirement or figure out a workaround using some kind of decorator pattern

In PHP, I can do the flowing code:

What you mean to say is that in PHP5 and only in PHP5 can you use interfaces... and that would only be true if the following code were correct.

interface A { function Get(); } class B extends A { function Get() {

       echo "class B";

} } class C extends A { echo "class C"; }

I'm very sure that the above class definition will generate a parse error... and correct me if I'm wrong (I'm not by the way), but don't you need to implement an interface versus extending it?

$a = new B(); $a->Get(); $a = new C(); $a->Get(); result: Class B Class C

At any rate, I fail to see the point of your response in relation to the OP's question.
