- a powerful tool for managing class dependencies and performing dependency injection.
- Dependency Injection Container and a Registry for the application
- responsible for managing class dependencies, meaning not every file needs to be injected in class manually but is done by the Service Container automatically.
- Service Container is mainly used in injecting class in controllers like Request object is injected. We can also inject a Model based on id in route binding.
public function profile(Request $request, User $id)
{
//
}
In the UserController profile method, the reason we can get the User model as a parameter is because of Service Container as the IoC resolves all the dependencies in all the controllers while booting the server. This process is also called route-model binding.
Request is also one example.
