Why Laravel's Service Container Feels Like Magic: Dependency Injection Explained

Short summary

A detailed tutorial demystifying Laravel's Service Container and dependency injection, using a restaurant analogy to explain how the container resolves object graphs automatically. It covers the problems of tight coupling—untestable and unchangeable code—and shows how DI shifts object construction responsibility to the framework. Includes code examples illustrating hard dependencies versus container-resolved injection.
