[Easy to understand] What are Service, Service Container and Service Provider in PHP Laravel?

Imagine you are running a restaurant. Let's break down the concepts of Service, Service Container, and Service Provider using this restaurant analogy:

• Service: In our restaurant analogy, a service is like a specific task or job that needs to be done. For example, a "Waiter Service" would involve taking orders, serving food, and delivering the bill to the customers. Each service has a specific responsibility.
• Service Container: The service container is like the restaurant itself. It holds all the services (tasks) that need to be performed. Just like how a restaurant has different sections (kitchen, dining area, bar), the service container in Laravel holds different services that can be accessed when needed. When a customer (controller) needs a specific service (task), they ask the restaurant (service container) to provide it.
• Service Provider: The service provider is like the manager of the restaurant. They are responsible for setting up the restaurant, organizing the services, and making sure everything runs smoothly. In Laravel, a service provider registers services with the service container so that they are available when needed. It acts as a bridge between the service container and the services.

Now, let's relate these concepts to Laravel:

• Service: LogoutService in our example is a specific service that handles the logout logic for users.
• Service Container: In Laravel, the service container is like a centralized place where all the services are registered and can be accessed. It manages the instantiation of objects and their dependencies.
• Service Provider: The service provider in Laravel is like the manager that registers the services with the service container. It tells the service container how to create instances of the services.

In our restaurant analogy, it's like the manager (service provider) making sure that the waiter service (service) is available in the restaurant (service container) to serve the customers (controllers) when they need it.

By using services, service containers, and service providers in Laravel, you can keep your code organized, modular, and easy to maintain, just like how a well-run restaurant operates smoothly with different tasks and roles defined.
