redis+thinkphp5的注册、登陆、关注基础例子

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。

thinkphp5 控制器的文件代码：

$age = I('post.age');
$uid = $redis->incr("userid");//$uid自增操作
$redis->hMset("user:$uid",array("uid"=>$uid,"username"=>$username,"password"=>$password,"age"=>$age));
//把用户结构存在链表里,每次注册一个用户，就向链表中插入一个用户
$redis->rPush("uid",$uid);
$redis->set("username:".$username,$uid);
$this->success('注册成功', 'Test/list_content');
