linux下 C语言对 php 扩展

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任性的反义词 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感动人生:

[ –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/significantphpize

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
/u祝福sr/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

<?php

say_hello();

?>

$ /usr/local/php/bin/php test.php

hello world.

则大功告成
