关于PHP的设计形式
关于PHP的设计模式
大家有没有 参与过比较系统的项目 或者 应用,你们在系统框架设计的思路是怎么样的?
现在很多人都谈MVC, 这种设计模式比较 易于维护。
也有人把MVC 引入到 php设计模式中,
但是我想问 MVC 真的适合php吗?
我总觉的 PHP 实现 MVC 很别扭, 毕竟一个php文件中的 程序,当它执行完后就被释放掉了, 而java/c# 中的程序是常住于内存中的, 所以PHP 中的 Module这层 每次调用都从头开始, 这样开销不会很大?
而且我认为 PHP 实现 MVC 这里面的 Controller 简直就是可有可无的。如果有这么设计过的肯定 也有我这种感受。
各位有什么高见呢?
------解决方案--------------------
MVC 一种软件架构模型,把软件系统分为三个基本部分:模型(Model)、视图(View)和控制器(Controller)。
既然是架构模型,就不存在是否适合某种语言的问题。他只不过是一种思路,一个看待事物的方法
MVC 也不象你说的那样 比较易于维护,相反 由于它的内部原理比较复杂,所以需要花费一些时间去思考。开发一个MVC模式架构的工程,将不得不花费相当可观的时间去考虑如何将MVC模式运用到应用程序中,同时由于模型和视图要严格的分离,这样也给调试应用程序带来了一定的困难。每个构件在使用之前都需要经过彻底的测试。另外由于MVC模式将一个应用程序分成了三个部件,所以这意味着同一个工程将包含比以前更多的文件。
Controller 简直就是可有可无的 少了 C 还是 MVC 吗?
Module这层 每次调用都从头开始, 这样开销不会很大? 不用 MVC 就没有开销了吗?所需的功能总是要有代码实现的吧?
------解决方案--------------------
其实mvc现在在,主流的开发语言中都在用。
其实mvc主要的作用不是提高性能,和加速。毕竟框架是有体积和损耗。
用mvc等等目的我个人认为主要是编码,维护,便于开发。
------解决方案--------------------
1楼,2楼说得很不错了,存在既有理,主要是一种思想,易于后期开发和维护,当然一开始我也觉得别扭,为什么要这样,把一个简单的事情要复杂化!

一些逻辑处理是在Controller中完成,怎会微不足道了呢。

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
