Sorry for the late response. You need the PHP MongoDB Library to be able to use this library.
http://mongodb.github.io/mongo-php-library/api/class-MongoDB.Client.html#_selectCollection

Simply install using composer and start using MongoDB.

I think if you need to select the database, you can put it behind the $dsn.
