/* 仿写CodeIgniter的FTP类
* FTP基本操作：
* 1) 登陆;                        connect
* 2) 当前目录文件列表;             filelist
* 3) 目录改变;                    chgdir
* 4) 重命名/移动;                 rename
* 5) 创建文件夹;                  mkdir
* 6) 删除;                        delete_dir/delete_file
* 7) 上传;                        upload
* 8) 下载                                                                   download
