因为公司平时用的是YII框架,所以和我理解的MVC突然就有了区别,下图是我理解的MVC

请问MVC模式的重点只是MVC三层吗?其中不同通信方式就和自身框架有关了?

前端控制器(路由)并不是MVC必需的设计模式.
MVC的核心思想是分离界面(View),逻辑(Controller),数据(Model).
比如浏览器访问页面控制器,控制器处理输入,调用模型获取数据,载入视图输出数据.
<code>/post.php?id=1024 //页面控制器(输入ID,输出文章) <?php if(!defined('APP_ROOT')) define('APP_ROOT', './'); //定义入口 require APP_ROOT.'include/common.php'; //加载模型(比如functions.php) $data = get_post(intval($_GET['id'])); //处理输入,调用模型获取数据 $view = render('post.php', $data); //载入视图输出数据 echo $view; //在控制器中获取视图需要的所有数据,并封装到$data数组中,传入模板. //如果你想在视图里直接调用模型数据,可以把render函数改为require. //这样视图跟控制器都在全局作用域,灵活性更强,但也要注意尽量不要在视图里写具体逻辑. //视图应该专注于调用并输出数据.</code></code>
/include/functions.php里的render()函数:
<code>function render($template, array $data = array()) { global $app; ob_start(); require APP_ROOT.'themes/'.$app['theme'].'/'.$template; $view = ob_get_contents(); ob_end_clean(); return $view; }</code>
mvc只是一种思想 不同的语言和框架都有各自的实现和改进 就像阮老师写的 他们只是在m v c三个层的侧重点不同
阮一峰的也不对,或者他有他的理解。 mvc并不是单向的。 m v c 之间的线估计会很多。 and mvc 就是mvc 。其他的db request router就不要扯进来了。
建议一开始不要扯什么mvc概念,找个框架用着用着,你自然就明白了。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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 originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
