PHP：如果没有curl扩展名，有没有办法下载文件？

Question

Is there a way to download files in case curl extension is not available or has been disabled?

This works too. Though you must have sockets enabled.

function getcontent($server,  $file,$port=80)
{
    $cont = "";
    $ip = gethostbyname($server);
    $fp = fsockopen($ip, $port);
    if (!$fp)
    {
        return "Unknown";
    }
    else
    {
        $com = "GET $file HTTP/1.1
Accept: */*
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
Host: $server:$port
Connection: Keep-Alive

";
        fputs($fp, $com);
        while (!feof($fp))
        {
            $cont .= fread($fp, 500);
        }
        fclose($fp);
        $cont = substr($cont, strpos($cont, "

") + 4);
        return $cont;
    }
}

Usage:

getcontent('google.com', '/intl/en_ALL/images/logo.gif');
