What is Service Container advanced binding techniques?

Beyond simple binding, Laravel's container supports advanced techniques. Binding interfaces to implementations: $this->app->bind(LoggerInterface::class, FileLogger::class). Singleton: $this->app->singleton() — same instance every time. Scoped singletons (Laravel 8+): $this->app->scoped() — singleton within a single request lifecycle, reset between Octane requests. Instance binding: $this->app->instance(Config::class, $configObject) — bind a specific object. Tagging: $this->app->tag([FileLogger::class, SlackLogger::class], "loggers") then resolve all: $this->app->tagged("loggers"). Extending: $this->app->extend(Logger::class, fn($service) => new DecoratedLogger($service)) — wrap a resolved service. These techniques enable sophisticated dependency management in complex applications.
