IntlCalendar::getActualMaximum
(PHP 5 >= 5.5.0, PHP 7, PHP 8, PECL >= 3.0.0a1)
IntlCalendar::getActualMaximum — The maximum value for a field, considering the objectʼs current time
Description
Object-oriented style
Procedural style
Returns a fieldʼs relative maximum value around the current time. The exact semantics vary by field, but in the general case this is the value that would be obtained if one would set the field value into the smallest relative maximum for the field and would increment it until reaching the global maximum or the field value wraps around, in which the value returned would be the global maximum or the value before the wrapping, respectively.
For instance, in the gregorian calendar, the actual maximum value for the
day of
month would vary between 28 and
31, depending on the month and year of the current time.
Parameters
-
calendar -
An IntlCalendar instance.
-
field -
One of the IntlCalendar date/time field constants. These are integer values between
0andIntlCalendar::FIELD_COUNT.
Return Values
An int representing the maximum value in the units associated
with the given field or false on failure.
Examples

$cal->add(IntlCalendar::FIELD_EXTENDED_YEAR, -1);
var_dump($cal->getActualMaximum(IntlCalendar::FIELD_DAY_OF_MONTH)); //29The above example will output:
int(28) int(29)
