IntlCalendar::add
(PHP 5 >= 5.5.0, PHP 7, PECL >= 3.0.0a1)
IntlCalendar::add — Add a (signed) amount of time to a field
Descrierea
Stil obiect-orientat
$field
, int $amount
) : boolStil procedural
Add a signed amount to a field. Adding a positive amount allows advances in time, even if the numeric value of the field decreases (e.g. when working with years in BC dates).
Other fields may need to adjusted – for instance, adding a month to the 31st of January will result in the 28th (or 29th) of February. Contrary to IntlCalendar::roll(), when a value wraps around, more significant fields may change. For instance, adding a day to the 31st of January will result in the 1st of February, not the 1st of January.
