In PHP 4 if the child doesn't define a constructor it's supposed to inherit the parents constructor. Only if you override the constructor do you need to call the parent constructor explicitly.

Did I understand this correctly: When I define a class Y extends X without providing Y::y() and X::x() is a constructor in X, a $y = new Y does call Y::x()? Ok, that works and it is probably the most confusing way to implement it. I think it sounds more like `real' OO behaviour, though I would expect Y::x() to be called even Y::y() exists. Also the support for `var $v' declarations breaks some things like in class A { function A() { $this->a = 1; } }; class B extends A { var $a = 2; function foo(){echo $this->a;} }; $z = new B; echo $z->foo(); This won't output 2 as expected but 1.

I don't quite agree. It should output 1. Your constructor changes it. If you don't want the constructor to be called then override it with a constructor for B. Andi --- Andi Gutmans <andi@zend.com> http://www.zend.com/
