PHP OOP Tutorial for absolute Beginners part -3 CLASS CONSTANT
Class constants
Just like defining other constants outside of a class using const keyword, we can also define them inside a class. The default visibility of class constants is public.
Constants are allocated once per class, and not for each class instance.
Scope Resolution Operator ::
Instead of using double colon allows access to static and constant. This operator is also used to access super class features.
Using self
Instead of using $this, the self keyword is used to access constants within the class. Generally, for all class level access self should be used and for all current object instance access $this should be used within the class.
