Instantiate new class instance inside Symfony services (Best practice)

In Symfony when I create a service and I need an instance of some classes, I pass them as parameter in service or I can create a new instance inside my functions service. I ask this because some Classes constructor needs parameters which I don’t have yet when passing the class as parameter.

Answer

you pass them as params in service. try to inject your deps to the max and not instantiate directly your services.
