高速开发一个PHP扩展
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.
