First look at the following commands
INT, TERM 立刻终止 QUIT 平滑终止 USR1 重新打开日志文件 USR2 平滑重载所有worker进程并重新载入配置和二进制模块
examples
1. pkill php-fpm 强制关闭2. kill -INT `cat /usr/local/php/var/run/php-fpm.pid` 3. /usr/local/php/sbin/php-fpm 启动 4. kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid` 平滑重启5. ps aux | grep -c php-fpm 查看php-fpm进程数:6. ps aux |grep php-fpm 查看php-fpm的master进程号
cat /usr/local/php/var/run/php-fpm.pid to view the php-fpm process number, you can use ps aux |grep php-fpm to view it
then use

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.

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 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),
