分享一段网友写的php实时推送代码: 

php 实时推送新发布的文章

socketopen方式推送sitemap

复制代码 代码如下:
 function sitemap_ping_baidu($urls){
         $baidu_ping_url = "ping.baidu.com";
         $get = "/sitemap?site=www.yourdomain.com&resource_name=sitemap&access_token=xxxxxxx";
         $port=80;
         if ( ( $io = fsockopen( $baidu_ping_url, $port, $errno, $errstr, 50 ) ) !== false )  {
             $send = "POST $get HTTP/1.1"."rn";
             $send .= "Accept: */*"."rn";
             $send .= "Cache-Control: no-cache"."rn";
 
           $send .= "Host: ".$baidu_ping_url."rn";
           $send .= "Pragma: no-cache"."rn";
           //$send .= "Referer: http://".$url.$get."rn";
           //$send .= "User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)"."rn";
           
           $xml = "<?xml version="1.0" encoding="UTF-8"?><urlset>";
           foreach($urls as $url){
               $xml .= "<url>";
               $xml .= "<loc><![CDATA[".$url."]]></loc>";
               $xml .= "<lastmod>".date("Y-m-d")."</lastmod>";
               $xml .= "<changefreq>monthly</changefreq>";
               $xml .= "<priority>0.8</priority>";
               $xml .= "</url>";
           }
           $xml .= "</urlset>";

           $send .= "Content-Length:".strlen($xml)."rn";
           $send .= "Connection: Closernrn";

           $send .= $xml."rn";

           fputs ( $io, $send );

           $return = "";
           while ( ! feof ( $io ) )
           {
               $return .= fread ( $io, 4096 );
           }
           return $return;
       }else{
           return false;
       }
   }
$return = sitemap_ping_baidu(array("http://www.yourdomain.com/a.php?id=1"));

推送后百度会返回的xml文档

复制代码 代码如下:
 <?xml version="1.0" encoding="UTF-8"?>
     <methodResponse>
         <params>
             <param>
                 <value>
                     <int>200</int>
                 </value>
             <param>
         </params>     
     </methodResponse>

状态码含义如下
