调用父类方法与调用静态方法

Question

To call a parent class (it has been instantiated) method I use

parent_class::method();  //tested it works

to call a method with in the instantiated class I am in I use

$this->method();  //tested it works

However if I call a static method from any class I use

parent_class::static_method();  //tested it works

I guess this makes since bc there is only one copy of a method per class, whether it is instantiated or not?

Can some one validate or provide insight to this. I just want to verify that the call method is the same for both static methods from any class and calls to a parent classes method.

Seems a bit strange.

The syntax is correct. Not exactly sure what your question is. If you wanted to call a static method defined in the child from within the child, you could use self::static_method() or $this->static_method() . Either would work.
