欢迎进入MyKTV点歌系统展示

 一个项目，一分收获；一个项目，一些资源。Ktv项目也是一样的，所以我想分享我的收获，让你们获得你需要的资源。

     一. 那MyKTV点歌系统具体的功能有哪些呢？我们就来看看吧!

    1.MyKTV前台功能：

     01.歌星点歌 、拼音点歌 、数字点歌 、类型选择 、金榜排行

     02.切歌 、点歌 、重唱和退出

 

     2.MyKTV后台功能：

      01.歌手管理 、歌曲管理 、设置资源路径

      02.新增歌手、歌曲 ,查询歌手、歌曲信息，设置歌曲路径和退出

 

      二. 功能已经概括的差不多了,就让我们一起来看看MyKTV的项目吧
