redis命令中文网参考网址:http://www.redis.cn/commands.html
首先我们需要下载一个类文件那就是predis
git地址：git clone git://github.com/nrk/predis.git
zip地址：https://github.com/nrk/predis/archive/v1.0.1.zip
然后我是嘴边创建了个本地文件引用的
接下来一个页面一个页面的看代码：
先连接redis,来一个redis.php
<?php
header("Content-type: text/html; charset=utf-8");
//载入redis文件
require ‘./predis/autoload.php‘;
//连接redis
$redis = new Predis\Client(array(
‘host‘=>‘127.0.0.1‘,
‘port‘=>6379
));
?>
注册：register.php

<h3>我的关注</h3>
<?php if($myguanzhu==null):?>
暂无关注
<?php else:?>
<?php foreach($gzinfo as $k=>$va){ ?>

<?php endif;?>
</li>
</body>
</html>
实现关注和被关注：addfans.php
<?php
include(‘./redis.php‘);
$uid = $_GET[‘uid‘];
$myuid = $_GET[‘myuid‘];
if($uid==$myuid){
echo ‘不能给自己点关注‘;
exit;
}
//添加redis
$redis->sadd("user:".$myuid.":following",$uid);
$redis->sadd("user:".$uid.":followers",$myuid);
echo "关注成功";
?>
最后是退出登录 loginout.php
<?php
setcookie(‘myuid‘,null);
header(‘location:login.php‘);
?>
基本上数据类型都是字符串或者hash
