  下面我们分别详述之:

  第一种方法:执行

  你最好为下面的代码创建函数或者是一个类,不过本文仅仅起到一个为您提供基本观念的作用,所以说你可以如此开始:

  

if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist")<br>  // log in at server1.example.com on port 22<br>  if(!($con = ssh2_connect("server1.example.com", 22))){<br>  echo "fail: unable to establish connection\n";<br>  } else {<br>  // try to authenticate with username root, password secretpassword<br>  if(!ssh2_auth_password($con, "root", "secretpassword")) {<br>  echo "fail: unable to authenticate\n";<br>  } else {<br>  // allright, we're in!<br>  echo "okay: logged in...\n";<br>  // execute a command<br>  if(!($stream = ssh2_exec($con, "ls -al" )) ){<br>  echo "fail: unable to execute command\n";<br>  } else{<br>  // collect returning data from command<br>  stream_set_blocking( $stream, true );<br>  $data = "";<br>  while( $buf = fread($stream,4096) ){<br>  $data .= $buf;<br>  }<br>  fclose($stream);<br>  }<br>  }

  第二种方法:外壳

  同样道理,你也可以为如下的代码编写函数或者一个类。不过,本文仅仅提供基本观念:

  

if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist")<br>  // log in at server1.example.com on port 22<br>  if(!($con = ssh2_connect("server1.example.com", 22))){<br>  echo "fail: unable to establish connection\n";<br>  } else {<br>  // try to authenticate with username root, password secretpassword<br>  if(!ssh2_auth_password($con, "root", "secretpassword")) {<br>  echo "fail: unable to authenticate\n";<br>  } else {<br>  // allright, we're in!<br>  echo "okay: logged in...\n";<br>  // create a shell<br>  if(!($shell = ssh2_shell($con, 'vt102', null, 80, 40, SSH2_TERM_UNIT_CHARS))){<br>  echo "fail: unable to establish shell\n";<br>  } else{<br>  stream_set_blocking( $shell, true );<br>  // send a command<br>  fwrite($shell,"ls -al\n");<br>  sleep(1);<br>  // & collect returning data<br>  $data = "";<br>  while( $buf = fread($shell,,4096) ){<br>  $data .= $buf;<br>  }<br>  fclose($shell);<br>  }<br>  }<br>  }
