//判断为空
if(empty($uname) || empty($pwd)){
    header("Refresh:3;url=reg.html");
    die("账号密码不能为空");
}

//验证唯一性（判断用户名是否存在）
$res=$redis->sIsMember('username',$uname);
if($res==1){
    //证明被注册
    header("Refresh:3;ur=reg.html");
    die("账号被注册");

<?php
//实例化
$redis=new Redis();
//长链接
$redis->pconnect("127.0.0.1","6379");
session_start();
//获取数据的id
$count=$redis->get("ping:count");
$arr=[];
for($i=1;$i<=$count;$i++){
    $arr[]=$redis->hGetAll("ping:".$i);
}
?>
当前登录的账号为：<?php echo $_SESSION['uname'] ?>
