: This article mainly introduces how to learn PHP-(13) Object-Oriented Programming 3 while logging. For more information about PHP tutorials, see. 2.3 Member methods (functions) The member method I understand is to execute some specific functions of this class, or what this class can do. It is no different from functions outside the class, but it is declared in the class. You need to use the class object
