php 读取远程网站内容[反盗连]

<script>ec(2);</script>

这是一款利用php fsockopen来读取远程服务器的内容哦，下面这段程序的做法就是可以反盗连呢，好了下面来看看吧。

 function DownloadToString()
   {
       $crlf = "rn";
       $response="";
       // generate request
       $req = 'GET ' . $this->_uri . ' HTTP/1.0' . $crlf
           .    'Host: ' . $this->_host . $crlf
           .    $crlf;
      
       // fetch
       $this->_fp = @fsockopen(($this->_protocol == 'https' ? 'ssl://' : '') . $this->_host, $this->_port);
       @fwrite($this->_fp, $req);
       while(is_resource($this->_fp) && $this->_fp && !feof($this->_fp))
           $response .= fread($this->_fp, 1024);
       @fclose($this->_fp);
      
       // split header and body
       $pos = strpos($response, $crlf . $crlf);
       if($pos === false)
           return($response);
       $header = substr($response, 0, $pos);
       $body = substr($response, $pos + 2 * strlen($crlf));
      
       // parse headers
       $headers = array();
       $lines = explode($crlf, $header);
       foreach($lines as $line)
           if(($pos = strpos($line, ':')) !== false)
               $headers[strtolower(trim(substr($line, 0, $pos)))] = trim(substr($line, $pos+1));
      
       // redirection?
       if(isset($headers['location']))
       {
           $http = new HTTPRequest($headers['location']);
           return($http->DownloadToString($http));
       }
       else
       {
           return($body);
       }
   }
}
