What is MVC?

For beginners, this part may not be well understood. Mvc is a design model that allows us to separate business logic from specific data display and layer it.

M:model model to complete the specific business logic

V:view, view, responsible for displaying information

C:controller, the controller is responsible for giving orders and plays the role of a traffic policeman (make a distinction and determine what to do when a demand comes from the front desk)

The basic principles and details are summarized in a picture:

Explain this: we enter url through the browser. When the request is processed by the server, the url will be parsed first, then classified according to the latter three parameters, the corresponding platform will be found according to the p parameter, the corresponding controller will be found according to c, the method in the corresponding controller will be found according to a, and then the corresponding controller will call the database model to carry out the corresponding database operation. And the logical processing of the data, and return the results, and then display by the view layer.

The complexity and diversity of functions of a website determines that there must be multiple controller to deal with different modules, so we can first define a base class of controller to save public methods and increase code reusability.

The advantage of mvc is clear: layering is clear and convenient for team development and modification.
