怎么判断file_get_contents来的数据是什么编码
如题

------解决方案--------------------
EUC-CN是GB 2312最常用的表示方法。浏览器编码表上的“GB2312”，通常都是指“EUC-CN”表示法。

不过你用 mb_detect_encoding 是不能得到正确的结果的
你把这个列表 "gb2312,gbk,utf-8" 里面的编码位置调一调看看
------解决方案--------------------
编码决定内容,内容不能决定编码,
比如看见一个gbk汉字,也完全可以看成是两个ISO-8859-1字符
所以mb_detect_encoding只能用猜的,既然是猜,不能完全保证正确(其实也没有绝对的正确)

对file_get_contents得到的内容,如果是一个web页面,可以用meta来判断,
如果没有这样的信息,只能"猜"

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
