本文实例讲述了php+redis实现注册、删除、编辑、分页、登录、关注等功能。分享给大家供大家参考，具体如下：

主要界面

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="注册"> <input type="reset" value="重填"></form>

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="add.php" rel="external nofollow" >注册</a><?php require("redis.php"); if(!empty($_COOKIE['auth'])){ $id = $redis->get("auth:".$_COOKIE['auth']); $name = $redis->hget("user:".$id,"username");?> 欢迎您：<?php echo $name;?> <a href="logout.php" rel="external nofollow" >退出</a> <?php } else { ?> <a href="login.php" rel="external nofollow" >登录</a> <?php } ?><?php require("redis.php"); //用户总数 $count = $redis->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:".$v); } ?><table border=1> <tr> <th>uid</th> <th>username</th> <th>age</th> <th>操作</th> </tr> <?php foreach($data as $v){ ?> <tr> <td><?php echo $v['uid']?></td> <td><?php echo $v['username']?></td> <td><?php echo $v['age']?></td> <td> <a href="del.php?id=<?php echo $v['uid'];?>" rel="external nofollow" >删除</a> <a href="mod.php?id=<?php echo $v['uid'];?>" rel="external nofollow" >编辑</a> <?php if(!empty($_COOKIE['auth']) && $id != $v['uid']){ ?> <a href="addfans.php?id=<?php echo $v['uid'];?>&uid=<?php echo $id;?>" rel="external nofollow" >加关注</a> <?php } ?> </td> </tr> <?php } ?> <tr> <td colspan="4"> <?php if(($page_num-1)>=1){ ?> <a href="?page=<?php echo ($page_num-1);?>" rel="external nofollow" >上一页</a> <?php } ?> <?php if(($page_num+1)<=$page_count){ ?> <a href="?page=<?php echo ($page_num+1);?>" rel="external nofollow" >下一页</a> <?php } ?> <a href="?page=1" rel="external nofollow" >首页</a> <a href="?page=<?php echo ($page_count);?>" rel="external nofollow" >尾页</a> 当前<?php echo $page_num;?>页 总共<?php echo $page_count;?>页 总共<?php echo $count;?>个用户 </td> </tr></table><!--关注功能，建议用集合实现，因为集合元素唯一，并且可以容易求出两个用户粉丝之间交集与差集，进而进行好友推荐功能--><table border=1> <caption>我关注了谁</caption> <?php $data = $redis->smembers("user:".$id.":following"); foreach($data as $v){ $row = $redis->hgetall("user:".$v); ?> <tr> <td><?php echo $row['uid'];?></td> <td><?php echo $row['username'];?></td> <td><?php echo $row['age'];?></td> </tr> <?php } ?><table><table border=1> <caption>我的粉丝</caption> <?php $data = $redis->smembers("user:".$id.":followers"); foreach($data as $v){ $row = $redis->hgetall("user:".$v); ?> <tr> <td><?php echo $row['uid'];?></td> <td><?php echo $row['username'];?></td> <td><?php echo $row['age'];?></td> </tr> <?php } ?><table>

退出

logout.php

<?php setcookie("auth","",time()-1); header("location:list.php");

登录

login.php

<?php require("redis.php"); $username = $_POST['username']; $pass = $_POST['password']; //根据注册时存储的以用户名为键的字符类型中查找用户id $id = $redis->get("username:".$username); if(!empty($id)){ $password = $redis->hget("user:".$id,"password"); if(md5($pass) == $password){ $auth = md5(time().$username.rand()); $redis->set("auth:".$auth,$id); setcookie("auth",$auth,time()+86400); header("location:list.php"); } }?><form action="" method="post"> 用户名:<input type="text" name="username"/><br> 密码:<input type="password" name="password"><br> <input type="submit" value="登录"/></form>

删除

del.php

<?php require("redis.php"); $uid = $_GET['id']; //echo $uid; $username = $redis->hget("user:".$id,"username"); $a=$redis->del("user:".$uid); $redis->del("username:".$username); $redis->lrem("uid",$uid); //var_dump($a); header("location:list.php");

编辑界面

mod.php

<?php require("redis.php"); $uid = $_GET['id']; $data=$redis->hgetall("user:".$uid);?><form action="doedit.php" method="post"> <input type="hidden" value="<?php echo $data['uid'];?>" name="uid"> 用户名:<input type="text" name="username" value="<?php echo $data['username'];?>"><br> 年龄:<input type="text" name="age" value="<?php echo $data['age'];?>"><br> <input type="submit" value="提交"> <input type="reset" value="重填"></form>

编辑功能

doedit.php

<?php require('redis.php'); $uid = $_POST['uid']; $username = $_POST['username']; $age = $_POST['age']; $a=$redis->hmset("user:".$uid,array("username"=>$username,"age"=>$age)); if($a){ header("location:list.php"); }else{ header("location:mod.php?id=".$uid); }

加关注

addfans.php

<?php//关注功能，建议用集合实现，因为集合元素唯一，并且可以容易求出两个用户粉丝之间交集与差集，进而进行好友推荐功能 $id = $_GET['id']; $uid = $_GET['uid']; require("redis.php"); $redis->sadd("user:".$uid.":following",$id); $redis->sadd("user:".$id.":followers",$uid); header("location:list.php");
