"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It calls the $this->open() method on the existing class when the class is instantiated, passing the name 'test.db' to the method as an argument for the open() method.  It does not return anything, so the test for the !$db return value is probably useless.  This code should exist in some kind of larger context where we might be able to understand the "bigger picture."
