note 75661 added to language.oop5

This is a simple problem but I cant figure this out in PHP. In C++ you can have two seperate classes each of which uses the other as a member. This is done by declaring the first class without defining it before defining the second class. //...in C++ class A; class B{ //stuff private: A m_a; }; class A{ //stuff private: B m_b; } Does anyone know if there is a way to achieve this result in PHP?
