<?php 
$fp = fopen($url, ‘r&#39;); 
stream_get_meta_data($fp);

  $result .= fgets($fp, 1024); 
  } 
echo “url body: $result”;

<?php 
    $url=&#39;https://www.adminn.cn/&#39;;

<?php 
function get_url ($url,$cookie=false) 
{ 
    $url = parse_url($url); 
    $query = $url[path].”?”.$url[query]; 
    echo “Query:”.$query; 
    $fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30); 
    if (!$fp) 
    { 
        return false; 
    } else { 
        $request = “GET $query HTTP/1.1rn”;
         $request .= “Host: $url[host]rn”; 
         $request .= “Connection: Closern”; 
         if($cookie) $request.=”Cookie:  $cookien”; 
         $request.=”rn”; 
         fwrite($fp,$request); 
         while(!@feof($fp)) 
         { $result .= @fgets($fp, 1024); 
         } 
         fclose($fp); 
         return $result;

 function GetUrlHTML($url,$cookie=false) {
  $rowdata = get_url($url,$cookie); 
  if($rowdata) 
  { 
      $body= stristr($rowdata,”rnrn”);
