本文實體講述了php+redis實作注冊、洗掉、編輯、分頁、登錄、關注等功能，分享給大家供大家參考，具體如下：
主要界面
?
連接redis
redis.php
1 <?php 2 //實體化 3 $redis = new Redis(); 4 //連接服務器 5 $a=$redis->connect("localhost",6379); 6 //var_dump($a); 7 //授權 8 $redis->auth("107lab");
注冊界面
add.php
1 <form action="reg.php" method="post"> 2 用戶名:<input type="text" name="username"><br> 3 密碼:<input type="password" name="password"><br> 4 年齡:<input type="text" name="age"><br> 5 <input type="submit" value="https://www.cnblogs.com/a609251438/p/注冊"> 6 <input type="reset" value="https://www.cnblogs.com/a609251438/p/重填"> 7 </form>
注冊實作
reg.php
1 <?php 2 require("redis.php"); 3 $username = $_POST['username']; 4 $password = md5($_POST['password']); 5 $age = $_POST['age']; 6 //echo $username.$password.$age; 7 $uid = $redis->incr("userid");//設定自增id，相當于主鍵 8 $redis->hMset("user:".$uid,array("uid"=>$uid,"username"=>$username,"password"=>$password,"age"=>$age));//用hash型別存盤用戶比較方便 9 //將用戶id存入一個鏈表中，便于統計資料 10 $redis->rpush("uid",$uid); 11 //將用id存入以用戶名為鍵的字符型別中，便于查看用戶是否存在， 12 $redis->set("username:".$username,$uid); 13 header('location:list.php'); 14 15
串列頁面

退出
logout.php
<?php setcookie("auth","",time()-1); header("location:list.php");
登錄
login.php
1 <?php 2 require("redis.php"); 3 $username = $_POST['username']; 4 $pass = $_POST['password']; 5 //根據注冊時存盤的以用戶名為鍵的字符型別中查找用戶id 6 $id = $redis->get("username:".$username); 7 if(!empty($id)){ 8 $password = $redis->hget("user:".$id,"password"); 9 if(md5($pass) == $password){ 10 $auth = md5(time().$username.rand()); 11 $redis->set("auth:".$auth,$id); 12 setcookie("auth",$auth,time()+86400); 13 header("location:list.php"); 14 } 15 } 16 ?> 17 <form action="" method="post"> 18 用戶名:<input type="text" name="username"/><br> 19 密碼:<input type="password" name="password"><br> 20 <input type="submit" value="https://www.cnblogs.com/a609251438/p/登錄"/> 21 </form>
洗掉
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");
編輯界面

編輯功能
doedit.php
1 <?php 2 require('redis.php'); 3 $uid = $_POST['uid']; 4 $username = $_POST['username']; 5 $age = $_POST['age']; 6 $a=$redis->hmset("user:".$uid,array("username"=>$username,"age"=>$age)); 7 if($a){ 8 header("location:list.php"); 9 }else{ 10 header("location:mod.php?id=".$uid); 11 }
加關注
addfans.php
1 <?php 2 //關注功能，建議用集合實作，因為集合元素唯一，并且可以容易求出兩個用戶粉絲之間交集與差集，進而進行好友推薦功能 3 $id = $_GET['id']; 4 $uid = $_GET['uid']; 5 require("redis.php"); 6 $redis->sadd("user:".$uid.":following",$id); 7 $redis->sadd("user:".$id.":followers",$uid); 8 header("location:list.php");
很多PHPer在進階的時候總會遇到一些問題和瓶頸，業務代碼寫多了沒有方向感，不知道該從那里入手去提升，對此我整理了一些資料，包括但不限于：分布式架構、高可擴展、高性能、高并發、服務器性能調優、TP6，laravel，YII2，Redis，Swoole、Swoft、Kafka、Mysql優化、shell腳本、Docker、微服務、Nginx等多個知識點高級進階干貨需要的可以免費分享給大家，需要的加群（點擊→）677079770
