Symfony核心类概述，symfony核心概述
本文讲述了Symfony核心类。分享给大家供大家参考，具体如下：
Symfony的核心类
Symfony的MVC方式使用了一些你以后会经常碰到的类
1. sfController是控制器，他解码请求并专递至动作（action）
2. sfRequest存储了所有的请求元素（参数、Cookies、头信息等等）
3. sfResponse包含了响应头信息和内容，这些是最终要转换为HTML并送与用户的东西
4. 一个上下文（通过sfContext::getInstance()获取）保存了所有核心对象的参考和现有的配置信息，他可以在任何位置被访问。
就像你看到的，所有的symfony类使用sf前缀，这可以避免和你自己的类或变量冲突，而且可以使核心框架的类容易识别。
代码的组织
你已经知道了symfony应用的不同组成，但也许还不知道他是如何组织的。
项目结构：应用、模块和动作
在symfony里，一个项目是一组制定域名下的服务和操作，他们共享对象模型。
一个项目是由多个应用组成，一个应用有多个模块组成，一个模块可以包含多个动作。
项目结构图：
Symfony的根树结构及描述

An advanced guide to PHP MVC architecture: unlocking advanced features
Mar 03, 2024 am 09:23 AM
The MVC architecture (Model-View-Controller) is one of the most popular patterns in PHP development because it provides a clear structure for organizing code and simplifying the development of WEB applications. While basic MVC principles are sufficient for most web applications, it has some limitations for applications that need to handle complex data or implement advanced functionality. Separating the model layer Separating the model layer is a common technique in advanced MVC architecture. It involves breaking down a model class into smaller subclasses, each focusing on a specific functionality. For example, for an e-commerce application, you might break down the main model class into an order model, a product model, and a customer model. This separation helps improve code maintainability and reusability. Use dependency injection
