使用方法訪問的時候自動ping到百度，我的方法是生成緩存，更新緩存的時候自動ping百度，返回結果為0表示成功。

復制代碼 代碼如下:

$pingarcurl='http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$arcping = new Ping('腳本之家',$pingarcurl,get_domain(),'http://www.49028c.com');
$arcping->pingbaidu();

復制代碼 代碼如下:

class ping{
private$title;//博客名稱
private$hosturl;//博客首頁地址
private$arturl;//新發文章地址
private$rssurl;//博客rss地址
private$baiduXML;//百度XML結構
private$baiduRPC;//百度XML地址

publicfunction__construct($title,$arturl,$hosturl,$rssurl)
{
if(empty($title)||empty($arturl))
returnfalse;
$this->title=$title;
$this->hosturl=$hosturl;

$this->arturl=$arturl;
