如何向远程服务器发送一个http的get请求？
你要什么?这个函数基本上都在这里了. 实际上它是类的一个方法.我是参照wordpress里面的track back模块改写的.你可以去下一个wordpress看看,
imbiss的Trackbak类(功能尚未完整).为方便阅读，现在转为gb2312了。
- <?php
- // 这是一个trackback sender程序
- // 中文技术规范参照 http://hedong.3322.org/archives/000351.html
- // 英文参照 http://www.sixapart.com/pronet/docs/trackback_spec
- // 现在的问题，在url后面附加了信息以后还要在正文内添加吗？
- //TPP.php
- //TrackbackPing.php

- var $debuginfo; //用来保存debug信息
