一搭建php环境
下载php 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 php/ext/
/ext_skel extname=my_ext
创建名字为my_ext的项目最终会生成my_extso
三更改配置和程序
$ vi ext/my_ext/configm
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 [ withmy_ext Include my_ext support])
修改成
PHP_ARG_WITH(my_ext for my_ext support
Make sure that the comment is aligned:
[ withmy_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 [ enablemy_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:
[ enablemy_ext Enable my_ext support])
$ vi ext/my_ext/php_my_exth
将
PHP_FUNCTION(confirm_my_ext_compiled); /* For testing remove later */
更改为
PHP_FUNCTION(say_hello);
$ vi ext/my_ext/my_extc
将
zend_function_entry phpcpp_functions[] = {
PHP_FE(confirm_my_ext_compiled NULL) /* For testing remove later */
{NULL NULL NULL} /* Must be the last line in phpcpp_functions[] */
};
更改为
zend_function_entry phpcpp_functions[] = {
PHP_FE(say_hello NULL)
{NULL NULL NULL} /* Must be the last line in phpcpp_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 withphpconfig=/usr/local/php/bin/phpconfig
$ make
这时会编译出 my_ext/modules/my_extso
五配置phpini
将my_extso放入/usr/local/php/ext/目录
$ vi phpini
修改添加如下
extension_dir = /usr/local/php/ext/
extension=my_extso
六测试
$ vi testphp
<?php
say_hello();
?>
$ /usr/local/php/bin/php testphp
hello world
则大功告成
