PHP - Static Methods
Static methods can be called directly - without creating an instance of the class first.
Static methods are declared with the static keyword.
To access a static method use the class name, double colon (::), and the method name.
A class can have both static and non-static methods. A static method can be accessed from a method in the same class using the self keyword and double colon (self::methodName()).
