suppose I have a static class A with static method b()
now suppose I have class C with class variable functionName = 'A';
so I want to invoke A's b() function in one line via the following:
//within class C $this->functionName::b();
however this ends up returning parse error....is there a way that I can invoke A::b() when via $this->functionName when $this->functionName = 'A' in just one line without call_user_func etc?
