奇怪!大家勿必来帮忙
请大家耐心看下去,帮我分析分析。

首先声明,文件是utf-8编码无疑,主机也都是linux。经多次测试——

现在用的两个主机分别是华夏名网和赢网的,下面的:

<a href="?str=%E7%88%B1%E6%97%A0%E9%99%90">爱无限</a><br /><?php<br />echo $_GET['str'];<br />?>


文件都能显示中文“爱无限”。代码接收表现正常。

但我新买了中电的空间,却发生奇怪的现象,即:
<a href="?str=%25E7%2588%25B1%25E6%2597%25A0%25E9%2599%2590">爱无限</a>(这里str参数——要再urlencode一次)<br /><?php<br />echo $_GET['str'];<br />?>




<a href="?str=%E7%88%B1%E6%97%A0%E9%99%90">爱无限</a><br /><?php<br />echo iconv( 'gb2312','utf-8', $_GET['str']);<br />?>


才能正确显示中文“爱无限”,是怎么回事呢!
文件编码已是utf-8为什么还要转呢,或者说中途怎么变了呢!

------解决方案--------------------
浏览器是utf-8编码么

爱无限  这样如何
------解决方案--------------------
既然你说“勿必来帮忙”,那我就路过算了


提示 ASCII(25)==%
------解决方案--------------------
查看一下主机默认的编码是不是utf8
------解决方案--------------------
http 头信息中有
MS-Author-Via: DAV
而 DAV 的含义是 The server's preferred method for authoring is WebDAV
WebDAV 是微软的 http 协议扩展

据此猜测该服务器总是按 unicode 编码处理多字节文字的
对应的中文就是 gbk

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.

PHP Dependency Injection: Boost Code MaintainabilityPHP Dependency Injection: Boost Code MaintainabilityMay 07, 2025 pm 02:37 PM

Dependency injection provides object dependencies through external injection in PHP, improving the maintainability and flexibility of the code. Its implementation methods include: 1. Constructor injection, 2. Set value injection, 3. Interface injection. Using dependency injection can decouple, improve testability and flexibility, but attention should be paid to the possibility of increasing complexity and performance overhead.

How to Implement Dependency Injection in PHPHow to Implement Dependency Injection in PHPMay 07, 2025 pm 02:33 PM

Implementing dependency injection (DI) in PHP can be done by manual injection or using DI containers. 1) Manual injection passes dependencies through constructors, such as the UserService class injecting Logger. 2) Use DI containers to automatically manage dependencies, such as the Container class to manage Logger and UserService. Implementing DI can improve code flexibility and testability, but you need to pay attention to traps such as overinjection and service locator anti-mode.
