Php MVC—将业务逻辑放入外部类而不是控制器或模型

我在Codeigniter中为我的应用程序创建外部类层次结构。 如下图所示

类层次结构

这些类位于“库”文件夹中。 整个项目文件结构如下所示

Codeigniter文件夹结构

 +-- controllers

在这里

使用的模型-数据处理

用于应用程序导航逻辑（连接模型和视图）的控制器

用于表示数据的视图（表示）

放入外部类层次结构的所有业务逻辑

models/Student_model.php

是的，但我们使用了不同的图案设计，我使用了类似这样的图案

我投票关闭这个问题，因为它看起来像是一个候选的，而不是一个编程问题本身。如果你需要用in控制器加载控制器，你不能用codeigniter MVC加载控制器，你需要一个第三方HMVC，我投票关闭这个问题，因为它看起来像，这本身不是一个编程问题。如果你需要用in控制器加载控制器，你不能用codeigniter MVC加载控制器，你需要第三方HMVC
