使用PHP进行telnet连接 [英] telnet connection using PHP

问题描述

我需要编写一个PHP脚本以telnet到路由器，运行命令并获取结果.有谁知道PHP中的telnet连接库?

I need to write a PHP script to telnet to a router, run a command and fetch the results. does anyone know a telnet connection library in PHP?

更新:该请求(很明显)是很久以前的.最后，我不得不编写自己需要的客户端库.该库(以及更多模块)的代码是开源的，可在

Update: This request (as is obvious) was for a long time ago. In the end I had to write the client library that I needed myself. The code for this library (and many more modules) is open source and available on github. Thanks everyone for your answers.

推荐答案

使用stdin/stream_select&阻止流为您提供了20行类似于客户端的telnet

using stdin/stream_select & blocking streams gives you a 20 lines telnet like client

<?

$socket = fsockopen("192.168.52.1", 8000);

if(!$socket)return;
stream_set_blocking($socket, 0);
stream_set_blocking(STDIN, 0);

do {
  echo "$ ";
  $read   = array( $socket, STDIN); $write  = NULL; $except = NULL;

  if(!is_resource($socket)) return;
  $num_changed_streams = @stream_select($read, $write, $except, null);
  if(feof($socket)) return ;


  if($num_changed_streams  === 0) continue;
  if (false === $num_changed_streams) {
      /* Error handling */
    var_dump($read);
    echo "Continue\n";
    die;
  } elseif ($num_changed_streams > 0) {
    echo "\r";
    $data = fread($socket, 4096);
    if($data !== "") 
      echo "<<< $data";

    $data2 = fread(STDIN, 4096);

    if($data2 !== "") {
      echo ">>> $data2";
      fwrite($socket, trim($data2));
    }
  }

} while(true);
