百度ping方法使用示例 自动ping百度

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"];
$arcping = new Ping("网页设计",$pingarcurl,get_domain(),"//www.rzxsoft.cn");
$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";

$this->baiduXML="<?xmlversion="1.0"encoding="UTF-8"?>";
$this->baiduXML.="<methodCall>";
$this->baiduXML.="<methodName>weblogUpdates.extendedPing</methodName>";
