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:
include("function.PHP"); include("header.PHP"); $content = I('content'); if(!$content){ error('内容不能够为空'); } $user = isLogin(); if($user==false){ header("location:index.PHP"); exit(); } $r = redis_connect(); $postid = $r->incr('global:postid'); //$r->set("post:postid:".$postid.":time",time()); //$r->set("post:postid:".$postid.":userid",$user['userid']); //$r->set("post:postid:".$postid.":content",$content); $r->hmset("post:postid:".$postid,array('userid'=>$user['userid'],'username'=>$user['username'],'time'=>time(),'content'=>$content)); //把微博推给自己的粉丝 $fans = $r->smembers("followed:".$user['userid']); $fans[] = $user['userid']; foreach($fans as $fansid){ $r->lpush('recivepost:'.$fansid,$postid); } //单独累计个人发布的信息 $r->lpush('userpostid:'.$user['userid'],$postid); header("location:home.PHP"); exit; include("bottom.PHP");
微博的关注代码:
include("function.PHP"); include("header.PHP"); if(isLogin()==false){ header("location:index.PHP"); exit; } $user = isLogin(); $uid = trim($_GET['uid']); $f = trim($_GET['f']); $r = redis_connect(); if($f==0){ //将关注与被关注的数据结构存入redis $r->sadd("following:".$user['userid'],$uid); $r->sadd("followed:".$uid,$user['userid']); }else{ //取消关注 $r->srem("following:".$user['userid'],$uid); $r->srem("followed:".$uid,$user['userid']); } //根据传递过来的userid查找username $uname = $r->get("user:userid:".$uid.":username"); header("location:profile.PHP?u=".$uname); include("bottom.PHP");
