无法通过telnet PHP登录服务器

Question

I'm using a [PHP Telnet Class][1] to connect to server via telnet to send commands. It connects to the server successfully but it fails to login in..

require_once "PHPTelnet.php";

$telnet = new PHPTelnet();

// if the first argument to Connect is blank,
// PHPTelnet will connect to the local host via 127.0.0.1

$result = $telnet->Connect('172.20.66.100','username','password');

if ($result == 0) {
   $telnet->DoCommand('another command', $result);

   echo $result;
   $telnet->Disconnect();}

=============================================================================== UPDATE: My script is working, there was some conflict going on with my virtual machine......

Try this:

    $url = 'tcp://ADDRESS_HERE:PORT_HERE';
    $fp = stream_socket_client($url, $errno, $errstr, 10);
    if (!$fp) {
        echo ("$errstr ($errno)<br />
");
        exit;
    } else {
        $command = 'execute_command_line' . PHP_EOL;
        fwrite($fp, $out);

        stream_set_blocking($fp, true);

        while (!feof($fp)) {
            $output = stream_get_contents($fp);
        }

        fclose($fp);
        echo output;
    }
