The difference between new static and new self in PHP

The difference between new static () and new self () in PHP

Self: Always points to the class itself, regardless of how many times the class has been inherited, which points to the class that originally used self;
Static: Pointing to a class that uses static, only through inheritance can the meaning of static exist be reflected, otherwise static and self are the same.

classA {publicfunctiongetStatic(){returnnewstatic();    }    publicfunctiongetSelf(){returnnewself();    }}classBextendsA{}var_dump((new B())->getSelf());//Avar_dump((new B())->getStatic());//B

Questions:
1, do not know the new static () and new self () what is the use;
2. If you want to use new self (), why not use new A ();
