Carbon 라이브러리 날짜, 요일 표기 (shortDayName, format, lastOfMonth, endOfMonth)

//2024-05-13 00:00:00
$startDay = \Carbon\Carbon::parse($booking_row->start_day); 

$startDay->toDateString(); //2024-05-13
$startDay->shortDayName; //월
$startDay->format('H:i'); // 20:15

 

• shortDayName : short name of weekday translated according to Carbon locale (한국: 월)

 

• lastOfMonth() : 그 달의 마지막 날이 시작된 순간을 얻을 수 있다 (00:00:00)
• endOfMonth() : 그 달의 마지막 날이 끝나는 순간을 얻을 수 있다 (23:59:59)

>>> echo today()->lastOfMonth();
2019-10-31 00:00:00
>>> echo today()->endOfMonth();
2019-10-31 23:59:59

 

• firstOfMonth() : 그 달의 첫날이 시작된 순간을 얻을 수 있다 (00:00:00)
• startOfMonth() : 그 달의 첫날이 시작된 순간을 얻을 수 있다 (00:00:00)

(동일)

>>> echo today()->firstOfMonth();
2019-10-01 00:00:00
>>> echo today()->startOfMonth();
2019-10-01 00:00:00

 

• startOfDay() : 그 날이 시작된 순간을 얻을 수 있다 (00:00:00)
• endOfDay() : 그 날이 끝나는 순간을 얻을 수 있다 (23:59:59)

>>> echo today()->startOfDay();
2019-10-17 00:00:00
>>> echo today()->endOfDay();
2019-10-17 23:59:59
