Bridging mode for PHP implementation of design Patterns

<?php/* Bridging mode: Separates the abstract and the implementation parts so that they can be independently changed. *  * in software systems, some types because of their own logic, it has two or more dimensions of the change, bridging mode is to deal with this multidimensional changes *//* example: different cars in different streets driving.
