  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")
  // log in at server1.example.com on port 22
  if(!($con = ssh2_connect("server1.example.com", 22))){
  echo "fail: unable to establish connection\n";
  } else {
  // try to authenticate with username root, password secretpassword
  if(!ssh2_auth_password($con, "root", "secretpassword")) {
  echo "fail: unable to authenticate\n";
  } else {
  // allright, we're in!
  echo "okay: logged in...\n";
  // execute a command
  if(!($stream = ssh2_exec($con, "ls -al" )) ){
  echo "fail: unable to execute command\n";
  } else{
  // collect returning data from command
  stream_set_blocking( $stream, true );
  $data = "";
  while( $buf = fread($stream,4096) ){
  $data .= $buf;
  }
  fclose($stream);
  }
  }

  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")
  // log in at server1.example.com on port 22
  if(!($con = ssh2_connect("server1.example.com", 22))){
  echo "fail: unable to establish connection\n";
  } else {
  // try to authenticate with username root, password secretpassword
  if(!ssh2_auth_password($con, "root", "secretpassword")) {
  echo "fail: unable to authenticate\n";
  } else {
  // allright, we're in!
  echo "okay: logged in...\n";
  // create a shell
  if(!($shell = ssh2_shell($con, 'vt102', null, 80, 40, SSH2_TERM_UNIT_CHARS))){
  echo "fail: unable to establish shell\n";
  } else{
  stream_set_blocking( $shell, true );
  // send a command
  fwrite($shell,"ls -al\n");
  sleep(1);
  // & collect returning data
  $data = "";
  while( $buf = fread($shell,,4096) ){
  $data .= $buf;
  }
  fclose($shell);
  }
  }
  }
