最近初步接触redis，结合thinkphp5与redis，写了一个用户注册的基础例子，用于学习。
这个例子是结合了兄弟连的redis视频，最后两节的内容写的：
https://study.163.com/course/courseMain.htm?courseId=265010
这个例子实现了以下功能：
（1）用户注册
（2）用户登陆
（3）redis+thinkphp5的数据的增加，修改，删除
（4）redis翻页功能
（5）用户的关注列表+粉丝列表
案例需要搭建的环境需求：
（1）thinkphp5
（2）redis
（3）phpredis（windows环境下也可以）
（4）redis desktop manager （用于观察redis server 的数据存储情况，当然这个不安装也可以）
说明：
（1）这个例子，主要是使用了phpredis的原生函数命令进行的redis的数据的增加，删除，修改等操作，并没有丰富thinkphp中的redis类库函数。
（2）涉及到了string，hash，set ，list数据类型，用于加深对redis数据类型的学习。
