Domain-Driven Design in PHP

Customize an Application Service

The main way to customize your Application Service is by choosing which dependencies you're passing in. Depending on your Service Container capabilities, that could be a bit tricky, so you can also add a setter to change the dependency on the fly. For example, you may need to change an output dependency so that you can set up a default one and then change it afterward. If logic gets too complicated, you can create an Application Service Factory that will handle this situation for you.
