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.
