What is wrong with the object-oriented inheritance feature of PHP?
A. The class uses the extends keyword so that child classes inherit the parent class.
B, subclasses can only inherit the non-private attributes of the parent class
C. After the class inherits the parent class, it is equivalent to copying the properties and methods of the parent class to the child class. You can use $ this directly
D, PHP only supports single inheritance, does not support one class to inherit multiple classes and multi-level inheritance
