[Original article] core of laravel, IoC container

Laravel's core isIoC containerAccording to the document, it is called"Service containerAs the name suggests, the container provides a series of services required in the entire framework. As a beginner, many people will have difficulties in this concept. Therefore, I plan to explain some basic content and understand the generation and solution of dependency in object-oriented development, to gradually unveil the "dependency injection" and gradually understand this magical design concept.

Most of this article uses examples to help readers understand what isIoC (control inversion)AndDI (dependency injection)To gain a deeper understanding of these concepts.
