使用方法访问的时候自动ping到百度，我的方法是生成缓存，更新缓存的时候自动ping百度，返回结果为0表示成功。

复制代码 代码如下:

$pingarcurl='http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

$arcping = new Ping('查字典教程网',$pingarcurl,get_domain(),'http://www.jb51.net');

$arcping->pingbaidu();

复制代码 代码如下:

class ping{

private$title;//博客名称

private$hosturl;//博客首页地址

private$arturl;//新发文章地址

private$rssurl;//博客rss地址

private$baiduXML;//百度XML结构

private$baiduRPC;//百度XML地址

publicfunction__construct($title,$arturl,$hosturl,$rssurl)

{

if(empty($title)||empty($arturl))

returnfalse;

$this->title=$title;

$this->hosturl=$hosturl;

$this->rssurl=$rssurl;

$this->arturl=$arturl;
