Read() Write() 命令产生不需要的资源 id #9

Question

我正在尝试使用 read() 和 write() 命令在服务器上运行一些 ping 命令。我正在使用连接到 Net_ssh2 的 phpseclib，但是当我尝试获取结果并查看 echo $this->ssh->getLog(); 中发生了什么时

这是进入路由器的 ssh：

$this->ssh->write('ssh '.$this->userid.'@'.$this->testIPAddress);
$this->ssh->write("\n");
$this->ssh->read('Password:');      
$this->ssh->write($this->passwd);
$this->ssh->write("\n");
$this->ssh->read('Welcome');

从那里我收到登录该路由器的成功消息，然后我运行以下 ping 命令：

 $this->ssh->write("ping 172.11.1.221");
 $this->ssh->write("\n");
 $testLineShowResult = $this->ssh->read('Type');

这是日志返回的内容：

如您所见，它多次打印资源 id #9...有人知道为什么吗？谢谢：D

我在 Google 上搜索到“在 '^' 标记处检测到无效输入”并找到了这个：

引用它，

On the switch you are connected to, does the prompt look similar to this:

switch>

If so, we need to type in "enable" to go into privileged mode, where the prompt will look like this:

switch#
