Contextual Binding for Improved Dependency Injection in Laravel

When you need different implementations of an interface based on the class that's requesting it, use contextual binding:

$this->app->when(PhotoController::class)
          ->needs(StorageInterface::class)
          ->give(CloudStorage::class);

$this->app->when(DocumentController::class)
          ->needs(StorageInterface::class)
          ->give(LocalStorage::class);

This allows you to inject different implementations of the same interface based on context, making your dependency injection more flexible while maintaining type-hinting throughout your application. Configure these bindings in your service providers to keep your controllers clean and focused on their responsibilities.
