为什么碳之间返回无效数据？

如何解决为什么碳之间返回无效数据？

在 laravel 8 中，我需要检查 $adItem->expire_date 是否会在接下来的 3 天内结束（$fullcalendar_nearest_days） 并制作

$today = Carbon::today()->startOfDay();
\Log::info(varDump($adItem->expire_date,' -00 $adItem->expire_date::'));
\Log::info(varDump($today,' -1 $today::'));

$expireDateCheckNearest = $today->addDays($fullcalendar_nearest_days)->startOfDay();
\Log::info(varDump($expireDateCheckNearest,' -1 $expireDateCheckNearest::'));


//                                       2021-06-30            2021-06-29      2021-07-02
$is_fullcalendar_nearest_days = $adItem->expire_date->between($today,$expireDateCheckNearest);
\Log::info(varDump($is_fullcalendar_nearest_days,' -1 $is_fullcalendar_nearest_days::'));

我看到日志输出：

我猜2021-06-30在2021-06-29和2021-07-02之间，不能赶上 为什么 $is_fullcalendar_nearest_days == false ？

解决方法

使用 addDays() 添加天数：

Carbon::now()->addDays(3);

此外，将它添加到查询中以获取总是一个好主意

->where('expire_date','>',Carbon::now()->addDays(3))
