Bridge in PHP
Bridge is a Conceptual design pattern that divides business logic or huge class into separate class hierarchies that can be developed independently.
One of these hierarchies (often called the Abstraction) will get a reference to an object of the second hierarchy (Implementation). The abstraction will be able to delegate some (sometimes, most) of its calls to the implementations object. Since all implementations will have a common interface, they’d be interchangeable inside the abstraction.
Usage of the pattern in PHP
Usage examples: The Bridge pattern is especially useful when supporting multiple types of database servers or working with several API providers of a certain kind (for example, cloud platforms, social networks, etc.)
