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'];
$arcping = new Ping('',$pingarcurl,get_domain(),'https://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;
$this->baiduRPC='http://ping.baidu.com/ping/RPC2';
