YY面试，对MVC框架M层的理解，求指导
根据我的理解，平时用来处理数据的方法，我把它封装成类，以后遇到同样的数据处理我就调用这个类，这个类属于M层，处理数据。

面试官问我：
我们抓取网页有这么几步
1.根据URL抓取网页
2.正则表达式处理html元素
3.将抓取到的内容存入数据库

以上这三部哪一步处于M层？

我觉得三步都属于啊。
求大家指导我的理解是否有错，错在哪里，拜托了~
如果上面三步哪一步不是M层，那它属于MVC的哪一层？？

------解决思路----------------------
1 是控制层 3是处理数据层我是这么理解
------解决思路----------------------
第三步，m是数据处理层，当然你应用逻辑也可以写在m层，只不过很不规范。
正确的mvc架构应该让c层尽可能少的处理数据逻辑，而让m来处理，否则mvc的最大优点－－代码模块化的优势就体现不出来了。
仅供参考！
------解决思路----------------------
MVC架构根本就没有准确定义，面试官水平不够或者故弄玄虚吧。
V是用户视角
C是业务视角
M是功能视角
三者本来就是一起合作完成任何一个功能的。抓取网页的话，对资源的请求一般写在M里。
正则表达式分析HTML这个，C和M都说得过去。在M里写好方法，C里调用是个比较好的结构。
数据库操作肯定是M，因为很多框架里，M就剩下访问数据库了。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

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.
