Carbonで次の特定曜日の日付を取得する方法

最近Carbonのnext/previousを見つけてテストコードや曜日に関連した処理を作るときにに便利そうだったのでメモです！

特定の日付から次の〇曜日を取得する

$today = Carbon::parse('2021/10/14');
// 2021/10/18(Mon)
dump($today->copy()->next(Carbon::MONDAY)->format('Y/m/d(D)'));
// 2021/10/19(Tue)
dump($today->copy()->next(Carbon::TUESDAY)->format('Y/m/d(D)'));
// 2021/10/20(Wed)
dump($today->copy()->next(Carbon::WEDNESDAY)->format('Y/m/d(D)'));
// 2021/10/21(Thu)
dump($today->copy()->next(Carbon::THURSDAY)->format('Y/m/d(D)'));
// 2021/10/15(Fri)
dump($today->copy()->next(Carbon::FRIDAY)->format('Y/m/d(D)'));
// 2021/10/16(Sat)
dump($today->copy()->next(Carbon::SATURDAY)->format('Y/m/d(D)'));
// 2021/10/17(Sun)
dd($today->copy()->next(Carbon::SUNDAY)->format('Y/m/d(D)'));

特定の日付から前の〇曜日を取得する

$today = Carbon::parse('2021/10/14');
// 2021/10/11(Mon)
dump($today->copy()->previous(Carbon::MONDAY)->format('Y/m/d(D)'));
// 2021/10/12(Tue)
dump($today->copy()->previous(Carbon::TUESDAY)->format('Y/m/d(D)'));
// 2021/10/13(Wed)
dump($today->copy()->previous(Carbon::WEDNESDAY)->format('Y/m/d(D)'));
// 2021/10/07(Thu)
dump($today->copy()->previous(Carbon::THURSDAY)->format('Y/m/d(D)'));
// 2021/10/08(Fri)
dump($today->copy()->previous(Carbon::FRIDAY)->format('Y/m/d(D)'));
// 2021/10/09(Sat)
dump($today->copy()->previous(Carbon::SATURDAY)->format('Y/m/d(D)'));
// 2021/10/10(Sun)
dd($today->copy()->previous(Carbon::SUNDAY)->format('Y/m/d(D)'));

Carbon便利ですね😊
