Redis实现注册、删除、编辑、分页功能

文章插图
 
连接redis
redis.php
<?php //实例化 $redis = new Redis(); //连接服务器 $a=$redis->connect("localhost",6379); //var_dump($a); //授权 $redis->auth("107lab");注册界面
add.php
<form action="reg.php" method="post"> 用户名:<input type="text" name="username"><br> 密码:<input type="password" name="password"><br> 年龄:<input type="text" name="age"><br> <input type="submit" value=https://www.isolves.com/it/sjk/Redis/2019-11-26/"注册"> 注册实现
reg.php
<?php require("redis.php"); $username = $_POST['username']; $password = md5($_POST['password']); $age = $_POST['age']; //echo $username.$password.$age; $uid = $redis->incr("userid");//设置自增id,相当于主键 $redis->hMset("user:".$uid,array("uid"=>$uid,"username"=>$username,"password"=>$password,"age"=>$age));//用hash类型存储用户比较方便 //将用户id存入一个链表中,便于统计数据 $redis->rpush("uid",$uid); //将用id存入以用户名为键的字符类型中,便于查看用户是否存在 。$redis->set("username:".$username,$uid); header('location:list.php');列表页面
list.php
<a href=https://www.isolves.com/it/sjk/Redis/2019-11-26/"add.php" rel="external nofollow" >注册get("auth:".$_COOKIE['auth']); $name = $redis->hget("user:".$id,"username");?> 欢迎您: 退出 登录 lsize("uid");//获取链表的长度 //echo $count; //页大小 $page_size = 3; //当前页码 $page_num=(!empty($_GET['page']))?$_GET['page']:1; //页总数 $page_count = ceil($count/$page_size); $ids = $redis->lrange("uid",($page_num-1)*$page_size,(($page_num-1)*$page_size+$page_size-1)); //var_dump($ids); foreach($ids as $v){ $data[]=$redis->hgetall("user:".$v); } /* //以下为最初想到的分页处理,放入一个数组中,根据uid的最大值来当总个数,但是删除个别用户以后,uid不会变小,所以建议用链表,因为他有个lsize函数可以求出链表长度 //根据userid获取所有用户 for($i=1;$i<=($redis->get("userid"));$i++){ $data[]=$redis->hgetall("user:".$i); } //过滤空值 $data = array_filter($data); //var_dump($data); */?>
uid username age 操作
删除 编辑 加关注
=1){ ?> 上一页 下一页 首页 尾页 当前页 总共页 总共个用户
smembers("user:".$id.":following"); foreach($data as $v){ $row = $redis->hgetall("user:".$v); ?>
我关注了谁
smembers("user:".$id.":followers"); foreach($data as $v){ $row = $redis->hgetall("user:".$v); ?>
