Static Keyword:
Declaring class properties or methods as static makes them accessible without needing an instantiation of the class. A property declared as static cannot be accessed with an instantiated class object (though a static method can).
Static methods:
Because static methods are callable without an instance of the object created, the pseudo-variable $this is not available inside the method declared as static.
Static properties:
Static properties cannot be accessed through the object using the arrow operator.
Like any other PHP static variable, static properties may only be initialized using a literal or constant before PHP 5.6; expressions are not allowed. In PHP 5.6 and later, the same rules apply as const expressions: some limited expressions are possible, provided they can be evaluated at compile time.
