这篇文章主要介绍了redis+php实现微博发布与关注功能,结合实例形式分析了php结合redis实现微博的发布及关注相关操作技巧,需要的朋友可以参考下。

本文实例讲述了redis+php实现微博发布与关注功能，分享给大家供大家参考，具体如下：

数据结构：

set post:postid:3:time timestamp

set post:postid:3:userid 5

set post:postid:3:content 测试发布哈哈哈哈

incr global:postid

set post:postid:$postidcho "用户名密码不能够为空!";

关注微博

following:3

被关注（粉丝）

followed:3

把发布的微博推给自己的粉丝

recivepost:10 postid

微博的发布代码：

1. include("function.php");
2. include("header.php");
3. $content = I('content');
4. if(!$content){
5. error('内容不能够为空');
6. }
7. $user = isLogin();
8. if($user==false){
9. header("location:index.php");
10. exit();
11. }
12. $r = redis_connect();
13. $postid = $r->incr('global:postid');
14. //$r->set("post:postid:".$postid.":time",time());
15. //$r->set("post:postid:".$postid.":userid",$user['userid']);
16. //$r->set("post:postid:".$postid.":content",$content);
17. $r->hmset("post:postid:".$postid,array('userid'=>$user['userid'],'username'=>$user['username'],'time'=>time(),'content'=>$content));
18. //把微博推给自己的粉丝
19. $fans = $r->smembers("followed:".$user['userid']);
20. $fans[] = $user['userid'];
21. foreach($fans as $fansid){
22. $r->lpush('recivepost:'.$fansid,$postid);
23. }
24. //单独累计个人发布的信息
25. $r->lpush('userpostid:'.$user['userid'],$postid);
26. header("location:home.php");
27. exit;
28. include("bottom.php");

微博的关注代码：

1. include("function.php");
2. include("header.php");
3. if(isLogin()==false){
4. header("location:index.php");
5. exit;
6. }
7. $user = isLogin();
8. $uid = trim($_GET['uid']);
9. $f = trim($_GET['f']);
10. $r = redis_connect();
11. if($f==0){
12. //将关注与被关注的数据结构存入redis
13. $r->sadd("following:".$user['userid'],$uid);
14. $r->sadd("followed:".$uid,$user['userid']);
15. }else{
16. //取消关注
17. $r->srem("following:".$user['userid'],$uid);
18. $r->srem("followed:".$uid,$user['userid']);
19. }
20. //根据传递过来的userid查找username
21. $uname = $r->get("user:userid:".$uid.":username");
22. header("location:profile.php?u=".$uname);
23. include("bottom.php");
