    or die("Could not connect to $ftp_server");
   
if($ftp) {
  echo "Successfully connected to $ftp_server!\n";
 
  //尝试登录
  if(@ftp_login($ftp, $ftp_user, $ftp_pass)) {
    echo "Connected as $ftp_user@$ftp_server\n";

    $command = 'ls -al >files.txt';

    //尝试执行命令
    if (ftp_exec($ftp, $command)) {
      echo "Command executed successfully\n";
    } else {
      die('Command failed');
    }

  } else {
    echo "Couldn't connect as $ftp_user\n";
  }
 
  //关闭连接
  if(ftp_close($ftp)) {
    echo "Connection closed successfully!\n"; 
  } 
}
