function get_content_by_socket($url){ 
$url = eregi_replace('^http://', '', $url);
$temp = explode('//m.sbmmt.com/m/', $url);
$host = array_shift($temp);
$url = ''.implode('//m.sbmmt.com/m/', $temp);
$temp = explode(':', $host);
$host = $temp[0];
$port = isset($temp[1]) ? $temp[1] : 80;
//echo $url;
//echo $host;
   $fp = fsockopen($host, 80) or die("Open ". $url ." failed"); 
    $header = "GET /".$url ." HTTP/1.1\r\n"; 
    $header .= "Accept: */*\r\n";

    fwrite($fp, $header); 
    while (!feof($fp)) { 
        $contents .= fgets($fp, 8192); 
    } 
    fclose($fp); 
    return $contents;
