文章利用了socket来实现异步调用哦，有需要学习socket的朋友可以参考一下。

<?
 $host = "www.hzhuti.com";
 $path = "/Report.php?ReportID=1";
 $cookie = Session_id();
 
 $fp = fsockopen($host, 80, $errno, $errstr, 30);
 if (!$fp) {
    print "$errstr ($errno)<br />n";
    exit;
 }
 $out = "GET ".$path." HTTP/1.1rn";
 $out .= "Host: ".$host."rn";
 $out .= "Connection: Closern";
 $out .= "Cookie: ".$cookie."rnrn";
 
 fwrite($fp, $out);  //将请求写入socket
 //也可以选择获取server端的响应
 /*while (!feof($fp)) {
     echo fgets($fp, 128);
 }*/
 //如果不等待server端响应直接关闭socket即可
 fclose($fp);
 ?>
