PHP uses Func_get_args and Func_num_args functions to implement overloaded instances of functions, Funcnumargs
The example in this paper describes the method of PHP using Func_get_args and Func_num_args functions to implement function overloading.

Function overloadC ++ allows you to overload functions with different parameter types. Overloaded functions and functions with polymorphism (that is, virtual functions)) The difference is that calling the correct entity of the overloaded function is
Explanation of the functions of extern C and extern
The main function of extern "C" is to call other C code correctly. After extern "C" is added, it indicates that the code of the compiler is compiled in C language instead of C ++. C ++ supports
1. inline functions: These functions exchange time at the cost of space (memory space (ProgramExecution efficiency). recursion is not allowed. It can be used for value transfer or address transfer, while macros cannot
