Editor to share with you the example analysis of the service container Ioc, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's learn about it!

The service container is a powerful tool for managing class dependencies and performing dependency injection.

For a class to be extracted by a container, it must first be registered with the container. Since we call this container a service container, if we need a service, we have to register and bind the service to the container first, then the thing that provides the service and binds the service to the container is the ServiceProvider.

Dependency injection and control inversion are different descriptions of the same thing from different angles. Dependency injection is described from the perspective of the application, which relies on the container to create and inject the external resources it needs. The control inversion is described from the point of view of the container, the container controls the application, and the container injects the external resources needed by the application into the application in reverse.
