This is not a bug. You are misusing constructors. What the new operator does is similar to C++. It first allocates memory for the object and then calls the objects constructor. The constructor does not have a return value and returning something from it is pointless. When you're calling new Bar(); you're telling PHP you want a new object of type Bar and not foo. Maybe what you want is inheritence?
