Php 使用 fsockopen发送http请求

<?php 

      function HTTP_Post($URL,$data, $referrer="") { 



        // parsing the given URL 

        $URL_Info=parse_url($URL); 



        // Building referrer 

        if($referrer=="") // if not given use this script as referrer 

          $referrer=$_SERVER["SCRIPT_URI"]; 



        // making string from $data 

        foreach($data as $key=>$value) 

          $values[]="$key=".urlencode($value); 

        $data_string=implode("&",$values); 



        // Find out which port is needed - if not given use standard (=80) 

        if(!isset($URL_Info["port"])) 

          $URL_Info["port"]=80; 



        // building POST-request: 

        $request.="POST ".$URL_Info["path"]." HTTP/1.1\n"; 

        $request.="Host: ".$URL_Info["host"]."\n"; 

        $request.="Referer: $referer\n"; 

        $request.="Content-type: application/x-www-form-urlencoded\n"; 

        $request.="Content-length: ".strlen($data_string)."\n"; 

        $request.="Connection: close\n"; 

        $request.="\n"; 

        $request.=$data_string."\n"; 



        $fp = fsockopen($URL_Info["host"],$URL_Info["port"]); 

        fputs($fp, $request); 

        while(!feof($fp)) { 

            $result .= fgets($fp, 128); 

        } 

        fclose($fp); 



        return $result; 

      } 



      $output1=HTTP_Post("http://www.example.com/script1.php",$_POST); 

      $output2=HTTP_Post("http://www.example.net/script2.php",$_POST); 

?>
