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。

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。

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.
