PHP TP5 实现用户签到

//获取Session中的用户ID

$where['userid'] = session('user.id') ;
$result = Sigins::getOne($where);
if(!$result){
    $data['userid'] = session('user.id') ;
    $data['sign'] = 1;  //初始连续签到天数
    $data['num'] = 10;  //初始签到积分
    $data['addtime'] = time();
    $model=new Sigins();
    $res = $model->insert($data);
    if($res){
        $this->success('恭喜您完成首次签到获得10积分！！');
    }
}else{
    $sigin_time = $result['addtime'];     //获取上次签到的时间
    $atNow = date('y-m-d');   //当天0点
    $newNow = strtotime($atNow);     //转化为时间戳
    $prevDay = $newNow - 86400;          //昨天0点
    $nextDay =  $newNow + 86400;         //明天0点
    if($sigin_time>$newNow && $sigin_time<$nextDay){
