A simple MVC model

: This article mainly introduces a simple MVC model. if you are interested in the PHP Tutorial, refer to it. MVC is a software method used to separate the logic layer and presentation layer of an application. In practice, because of this separation, your page contains only a few PHP scripts.
The model represents your data structure. Generally, model classes include methods to help you add, delete, modify, and query databases.
A view is the information to be presented to users. A view is usually a web page.
A controller is an intermediary between a model, a view, and any other resources necessary to process an HTTP request and generate a webpage.
Make a simple MVC model.
1. index. php
