rename和copy
win7 + php5.3.8

header("Content-type: text/html; charset=UTF-8");<br />//define('ROOT_DIR', $_SERVER['DOCUMENT_ROOT'] . '/');<br />rename("/upload/word.rar", "/word.rar");<br />echo "你好";<br /><br />/**<br /> * 问题1<br /> * 当文件编码为utf-8, header也设置为utf-8<br /> * rename报错为乱码(下图), 为什么?<br /> * 而header设置为GBK, 报错显示才正常<br /> *<br /> * 问题2<br /> * word.rar有600多M, rename瞬间完成, 而copy差不多得需要5~10秒这样, 为什么相差这么大<br />*/

rename
只能修改名称，不能移动目录
------解决思路----------------------
1、正常时，错误信息是什么？
2、rename 只改变目录项，当然很快
copy 要抄写一遍文件，自然就慢了
------解决思路----------------------
1、你用什么浏览器测试的，换个浏览器测试看看。
------解决思路----------------------
“系统找不到指定的路径” 这个错误信息是操作系统发出的
你使用的是简体中文 windows，那么信息就是 gbk 编码的，在 utf-8 环境中当然是乱码

Best Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

Best PHP Performance Optimization TechniquesMay 07, 2025 pm 03:05 PM

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.
