INTLCALENDAR.GETMINIMALDAYSINFIRSTWEEK(3)				 1				 INTLCALENDAR.GETMINIMALDAYSINFIRSTWEEK(3)

IntlCalendar::getMinimalDaysInFirstWeek - Get minimal number of days the first week in a year or month can have

	Object oriented style

SYNOPSIS

       public int IntlCalendar::getMinimalDaysInFirstWeek (void  )

DESCRIPTION

	Procedural style
       int intlcal_get_minimal_days_in_first_week (IntlCalendar  $cal)

	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(3); otherwise it will be the previous years last week.

PARAMETERS

	      o $cal
		- The IntlCalendar resource.

RETURN VALUES

	An int representing a number of days or FALSE on failure.

EXAMPLES

       Example #1

	      IntlCalendar.getMinimalDaysInFirstWeek(3)

	      <?php
	      ini_set('date.timezone', 'UTC');
	      ini_set('intl.default_locale', 'en_US');

	      $cal = new IntlGregorianCalendar(2013, 0 /* January */, 2);
	      var_dump(IntlDateFormatter::formatObject($cal, 'cccc')); // Wednesday

	      var_dump($cal->getMinimalDaysInFirstWeek(), // 1
	      $cal->getFirstDayofWeek()); // 1 (Sunday)

	      // Week 1 of 2013
	      var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

	      $cal->setMinimalDaysInFirstWeek(4);
	      // Still Week 1 of 2013 (1st week has 5 days in the new year)
	      var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

	      $cal->setMinimalDaysInFirstWeek(6);
	      // Week 53 of 2012
	      var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

	      The above example will output:

	      string(9) "Wednesday"
	      int(1)
	      int(1)
	      string(14) "Week 1 of 2013"
	      string(14) "Week 1 of 2013"
	      string(15) "Week 53 of 2012"
