Here you are calling the static method of the Pagination class which returns the stdClass object which you are assigning to $pagination_obj. > > We will have an object ($pagi_obj) returned where the properties of that > object will be *referring* to the values passed on the method argument, right? $pagi_obj is what is was in the Pagination class, but when it was returned you assigned it to $pagination_obj. > How does those $pagi_obj properties, can then be accessible by doing > $pagination_obj->offset; ?

The Pagination class built the object for you and assigned those vars to it. It then returned the object and you assigned it the name $pagination_obj.
