Returns the smallest number of days the first week of a year or month must have in the new year or month. For instance, in the Gregorian calendar, if this value is 1, then the first week of the year will necessarily include January 1st, while if this value is 7, then the week with January 1st will be the first week of the year only if the day of the week for January 1st matches the day of the week returned by IntlCalendar::getFirstDayOfWeek(); otherwise it will be the previous yearʼs last week.

参数

cal

The IntlCalendar resource.

返回值

An int representing a number of days 或者在失败时返回 false.
