HomeBackend DevelopmentPHP Tutorial PHP中cookie传值出现乱码有关问题

PHP中cookie传值出现乱码问题
$username=mb_convert_encoding($row1[0], "GBK", "UTF-8");
setcookie('username',$username);
这个通过setcookie在页面上会出现乱码
但是通过setrawcookie会报错,未定义函数的错误
请教一下如何写cookie以及如何读取cookie

------解决方案--------------------
你设置的 cookie 是给 js 用的吗?
如果是,出现乱码是你读取 cookie 的函数有问题
如果是个 php 用的,那么本来 utf-8 编码的内容被你转成 gbk 的了。再读回来不还是 gbk 的吗?不转回来自然就是乱码了
------解决方案--------------------
楼上的正解啊,$username=mb_convert_encoding($row1[0], "GBK", "UTF-8");
setcookie('username',$username);
楼主可以试一下 setrawcookie()这个行不行。其实输出的时候转码就可以了
$a=mb_convert_encoding($_COOKIE["username"],"UTF-8" , "GBK");就ok了试试行不行

Dependency Injection vs. Service Locator in PHPDependency 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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF

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),
