一、用户注册登录

include "./header.php";
    include "./function.php";
    $username = p("username");
    $password = p("password");
    $password2 = p("password2");
    if ($password != $password2) {
        redirect("./login.php", "两次密码输入不一致", 3);
    }
    if (!$username || !$password) {
        redirect("./login.php", "请输入用户名或秘密", 3);
    }
    $redis = connRedis();
    /*
        用户表设置
        user:id:1:username
        user:id:1:password
        user:username 1
    */
    $id = $redis->incr("global:user");
    $redis->set("user:id:$id:username", $username);
    $redis->set("user:id:$id:password", $password);
    $redis->set("user:username:$username", $id);
    //维护一个最新50个用户的表
    $redis->lpush("newuser", $id);
    $redis->ltrim("newuser", 0, 49);
    redirect("./login.php", "用户名：$username 注册成功", 3)

　 include "./header.php";
    include "./function.php";
    $username = p("username");
    $password = p("password");
    if (!$username || !$password) {
        redirect("./login.php", "请输入用户名或秘密", 3);
    }
    $redis = connRedis();
    $id = $redis->get("user:username:$username");
    $oldPassword = $redis->get("user:id:$id:password");
    closeRedis($redis);
    if ($password != $oldPassword) {
        redirect("./login.php", "用户名或秘密不正确", 3);
    }
    //设置cookie
    setcookie("id", $id);
    setcookie("username", $username);
    setcookie("password", $password);
    redirect("./home.php", "登录成功", 3);

二、发表动态

include "./header.php";
    include "./function.php";
    $status = p("status");
    if (empty($status)) {
        redirect("./home.php", "请输入内容", 3);
    }
    /*
        post表（发动态表）
        post:id:1:uid 
        post:id:1:content
    */
    $redis = connRedis();
    $id = $redis->incr("global:post");
    $redis->hMset("post:id:$id", array("uid" => $_COOKIE["id"], "content" => $status, "time" => date("Y-m-d H:i:s", time()), "username" => $_COOKIE["username"]));
    //最近50条发布的信息
    $redis->lpush("newpost", $id);
    $redis->ltrim("newpost", 0, 49);
    //获取我的粉丝，并把我的动态发给他
    $fans = $redis->smembers("flowing:userid:{$_COOKIE["id"]}");
    $fans[] = $_COOKIE["id"];
    foreach ($fans as $fansid) {
        $redis->lpush("receivepost:$fansid", $id);
    }

三、关注页

include "./header.php";
    include "./function.php";
    $uid = g("uid");
    $f = g("f");
    $redis = connRedis();
    $u = $redis->get("user:id:$uid:username");
    if (!$u) {
        redirect("./home.php", "非法数据", 3);
    }
    if ($f) {
        //关注
        $redis->sAdd("flow:userid:{$_COOKIE["id"]}", $uid);
        $redis->sAdd("flowing:userid:$uid", $_COOKIE["id"]);
        $msg = "关注成功";
    }else{
        //取消
        $redis->srem("flow:userid:{$_COOKIE["id"]}", $uid);
        $redis->srem("flowing:userid:$uid", $_COOKIE["id"]);
        $msg = "取消关注成功";
    }
    redirect("./profile.php?u=$u", $msg, 3);

四、热点页

include_once("./header.php");
    include_once("./function.php");
    if (!$_COOKIE["id"]) {
        redirect("./login.php", "请先登录", 3);
    }
    $redis = connRedis();
    $data = $redis->sort("newuser", array("get" => "user:id:*:username", "limit" => array(0,1), "sort" => "desc"));
    //获取最新发布的动态id
    $newpost = $redis->lRange("newpost", 0, -1);
