RE: [PHP] Re: Polymorphism in PHP

I must be missing something in your question, because I just tried your script below and it worked as advertised. Did you try the script and it failed? -----Original Message----- From: Richard Fox [mailto:rfox@sbsii.com] Sent: Monday, February 18, 2002 2:13 PM To: PHP Subject: [PHP] Re: Polymorphism in PHP That's right, the difference between C++ "pure virtual" and "virtual" is that a virtual function has an implementation but pure virtual only defines an interface. But can we get back to my original PHP question: Can I do something like the following in php: class Base { function Foo() { echo "Base"; } } class Derived1 extends Base { function Foo() { echo "Derived1"; } } class Derived2 extends Base { function Foo() { echo "Derived2"; } } function Example ( $objvar ) { $objvar->Foo(); } ... $obj1 = new Base(); $obj2 = new Derived1(); $obj3 = new Derived2(); Example($obj1); Example($obj2); Example($obj3); I think what I am asking is, is there any concept of a virtual function in PHP, with a virtual function table?
