试试
<?php 
$messageurl="http://www.google.com"; 
if ($messageurl."" <> "") { 
echo getURLContent($messageurl); 
} 
function getURLContent($sURL) 
{ 
        $pURL=parse_url($sURL);         $pScheme = $pURL["scheme"]; 
        $pServer = $pURL["host"]; 
        $pPort  = ($pURL["port"]=="")?80:$pURL["port"]; 
        $pPath  = $pURL["path"]; 
        
        $pPath  .= ($pURL["query"]=="")?"":"?".$pURL["query"]; 
        $fp = fsockopen($pServer,80,$errNo,$errStr,30);         if (!$fp) { 
return "";         } else { 
                $out  = "GET ". '/'.$pPath." HTTP/1.0\r\n";  //                $out  = "GET ".$pServer .$pPath." HTTP/1.0\r\n"; 
                $out .= "Accept: */*\r\n"; 
                $out .= "Host: ".$pServer."\r\n"; 
                $out .= "Connection: Close\r\n\r\n";                 fwrite($fp, $out); 
                $retContent=""; 
                while (!feof($fp)) { 
                        $retContent.=fgets($fp, 4096); 
                } 
                fclose($fp); 
return $retContent; 
        } 
} ?> 查了一下http协议出错在于请求资源或url不对要么给url,要么指定/根域

Answer 4

                $out  = "GET ". '/'.$pPath." HTTP/1.0\r\n";    //或$out  = "GET ".$pServer .$pPath." HTTP/1.0\r\n"; 
                $out .= "Accept: */*\r\n";   //
