快速开发一个PHP扩展
本文通过非常快速的方式讲解了如何制作一个PHP 5.2 环境的扩展(PHP Extension),希望能够在图文的方式下让想快速学习的朋友了解一下制作过程。
需求:比如开发一个叫做 heiyeluren 的扩展,扩展里就一个函数 heiyeluren_test(),输入一个字符串,函数返回:Your input string: xxxxx。
要求:了解C/C++编程,熟悉PHP编程
环境:下载一份php对应版本的源码,我这里是 php-5.2.6,先正常安装php,假设我们的php安装在 /usr/local/php 目录,源码在 /root/soft/php/php-5.2.6/,现在开始!
步骤一:生成扩展框架
cd /root/soft/php/php-5.2.6/ext
./ext_skel --extname=heiyeluren
cd /root/soft/php/php-5.2.6/ext/heiyeluren
vi config.m4
打开文件后去掉 dnl ,获得下面的信息:
PHP_ARG_ENABLE(heiyeluren, whether to enable heiyeluren support,
[ --enable-heiyeluren Enable heiyeluren support])
保存退出.

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.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
