win 7下的php 第一天
（1)下载安装工具 wampServer
(2)排除obstacle，
先关闭iis
1）关闭iis服务 iisadmin
2）关闭iis下的虚拟主机实例，默认的网站（中间现实一个IIS的大jpg图像，指向iis.net），
win7下 “控制面板” - “管理工具” “IIS管理器” 删除应用即可。
如果使用端口查看器，会发现，80端口被系统所占用了，尽管进程选项中并没有出现iisadmin这一项，但是它被默认启动了，
被装入了windows的服务项，也就是说，只要你在iis上设置了这个虚拟目录，那么它就会在你登陆windows的时候把它装载进来，并且
占用了你的80端口，
使我的apache用不了（因为占用了80端口）
好了，现在我已经成功的进入了我的wampServer了。
真令人高兴啊。~~

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect 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 TestabilityMay 12, 2025 am 12:03 AMDependency 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 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),
