static properties and methods
Class properties and methods can be declared with static keyword which makes them class level features and we don't need a class instance to access those features.
Like class constants we access static properties/methods with double colon (::) and to access them within class we use self keyword.
$this is not available inside a static method.
By default static features have 'public' accessibility.
For static variable initialization, the same rules apply as const expressions.
