Answer 1

you can have a static method in your database class wich will return an instance of itself.

$db = DB::getInstance();

moreover you can implement a singleton pattern. you can read about it here.

PHP Patterns

The main idea is that you save your DB object in static property and then in getInstance check if it's set you return it or create new one, constructor should be made private so that the Object can't be created anywhere else but in getInstance.. this ensures that there is always one Instance of DB object.
