programming languages use the functions of other languages to introduce new functions. Think about Java 8, C ++ 11, Python3, and PHP7. these are just a few examples. Because the code libraries of the top 10 popular languages are huge, users prefer to implement changes in the language, rather than using new programming languages.

This is also one of the advantages of COM, which is platform-independent, no matter whether you are remote, local, or in-process, programming is the same, and all the details are handled by com itself, so we do not need to go into this issue, you only need to have a concept. Of course, if you have special requirements for scheduling, you need to have a deep understanding

In the object-oriented programming of PHP, you will always encounter
Class test{public static function test () { self::func (); Static::func (); } public static function Func () {}}
But do you know the difference between self and static?
In fact, the difference is very simple, just need to write a few demo can understand:
Demo for self:
Class car{public static function model () { self::getmodel ();} protected static function Getmodel () { echo
