$redis->hmset("user:".$uid,array("uid"=>$uid,"username"=>$username,"password"=>$password,"age"=>$age));

$redis->rpush("uid",$uid);

$redis->set("username:".$username,$uid);

header("location:list.php");

4、list.php，用户列表

require("redis.php");

if(!emptyempty($_COOKIE['auth'])){

$id = $redis->get("auth:".$COOKIE['auth']);

$name = $redis->hget("user:".$id,"username");

?>

欢迎您，<?php echo $name?>,退出

}else{

?>

登陆

}

//用户总数

$count = $redis->lsize("uid");

//页大小

$page_size = 3;

//当前页码

$page_num = (!emptyempty($_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);

/*

for($i=1;$i<=($redis->get("userid"));$i++) {

$data[] = $redis->hgetall("user:".$i);

}*/

foreach($ids as $v){

$data[] = $redis->hgetall("user:".$v);

}

//var_dump($data);

//$data = array_filter($data);

?>

uid	username	age	操作
<?php echo $v['uid']?>	<?php echo $v['username']?>	<?php echo $v['age']?>	删除 编辑 加关注
上一页 下一页 首页 尾页 当前<?php echo $page_num ?>页 总共<?php echo $page_count ?>页 总共<?php echo $count ?>个用户

<?php $data = $redis->smembers("user:".$id.":following");?>

foreach($data as $v) {

$row = $redis->hgetall("user:".$v);

<?php echo $row['uid']?><?php echo $row['username']?><?php echo $row['age']?>

}

?>

$data = $redis->smembers("user:".$id.":followers");

foreach($data as $v) {

$row = $redis->hgetall("user:".$v);

?>

<?php echo $row['uid']?><?php echo $row['username']?><?php echo $row['age']?>

}

?>

5、del.php，用户删除

require("redis.php");

$uid = $_GET['id'];

$redis->del("user:".$uid);

$redis->lrem("uid",$uid);

header("localhost:list.php");

6、mod.php

require("redis.php");

$uid = $_GET['id'];

$data = $redis->hgetall("user:".$uid);

?>

用户名：

年龄：

7、doedit.php，信息更新

$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);

}

8、login.php，登录页面

require("redis.php");

$username = $_POST['username'];

$pass = $_POST['password'];

$id = $redis->get("username:".$username);

if(!emptyempty($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");

}

}

?>

用户名：

密码：

9、logout.php，退出

setcookie("auth","",time()-1);

header("location:list.php");

10、adfans.php，添加关注

$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");

当然，采用sdiff user:1:following user:2:following语句，用户1可以向用户2推荐关注(即用户1的关注与用户2的关注的差集)。
