Answer 1

There is no difference in the two :

public static function
static public function

Both a accessible outside of the class. In both, you can’t use $this inside the function because a static function does not requiere an object to be instanciated.

Consider you have a Cars class.

// Constructors call to a private static function add_this_car();
$car1 = new Cars('bentley');
$car2 = new Cars('Porsche GT1');

// public static function get_created_cars();
$all_cars = Cars::get_created_cars();

This way a class can take care of all instances of it there is (and a reference to each). And things that should be handle by the class itself and do not requiere an instance to be created.
