一，搭建php环境

下载php 5.2.6 源码 并解压

编译安装，搭建php环境

二，创建扩展项目

进入源码目录

cd php5.2.6/ext/
./ext_skel --extname=my_ext

创建名字为my_ext的项目，最终会生成my_ext.so

三，更改配置和程序

$ vi ext/my_ext/config.m4

根据你自己的选择将

dnl PHP_ARG_WITH(my_ext, for my_ext support,
dnl Make sure that the comment is aligned:
dnl [ --with-my_ext Include my_ext support])

修改成

PHP_ARG_WITH(my_ext, for my_ext support,
Make sure that the comment is aligned:
[ --with-my_ext Include my_ext support])

或者将

dnl PHP_ARG_ENABLE(my_ext, whether to enable my_ext support,
dnl Make sure that the comment is aligned:
dnl [ --enable-my_ext Enable my_ext support])

修改成

PHP_ARG_ENABLE(my_ext, whether to enable my_ext support,
Make sure that the comment is aligned:
[ --enable-my_ext Enable my_ext support])
$ vi ext/my_ext/php_my_ext.h

将

PHP_FUNCTION(confirm_my_ext_compiled); /* For testing, remove later. */

更改为

PHP_FUNCTION(say_hello);
$ vi ext/my_ext/my_ext.c

将

zend_function_entry php5cpp_functions[] = {
PHP_FE(confirm_my_ext_compiled, NULL) /* For testing, remove later. */
{NULL, NULL, NULL} /* Must be the last line in php5cpp_functions[] */
};

更改为

zend_function_entry php5cpp_functions[] = {
PHP_FE(say_hello, NULL)
{NULL, NULL, NULL} /* Must be the last line in php5cpp_functions[] */
};

在最后添加：

PHP_FUNCTION(say_hello)
{
zend_printf("hello world\n");
}

四，编译

$ cd my_ext
$ /usr/local/php/bin/phpize
ps: 如果出现：Cannot find autoconf.……的错误信息，则需要安装 autoconf (安装过程略)
$ ./configure --with-php-config=/usr/local/php/bin/php-config
$ make

这时会编译出 my_ext/modules/my_ext.so

五，配置php.ini

将my_ext.so放入/usr/local/php/ext/目录
$ vi php.ini

修改添加如下：

extension_dir = '/usr/local/php/ext/'
extension=my_ext.so

六，测试

$ vi test.php
say_hello();
?>
$ /usr/local/php/bin/php test.php
hello world.

则大功告成
