Why can't I ask for end date on a period based on recurrences?
I understand I never specified such a property, but it's a really easy calculation... shouldn't it be built in?
PHP - Manual: DatePeriod::getEndDate
2024-12-22
(PHP 5 >= 5.6.5, PHP 7, PHP 8)
DatePeriod::getEndDate — Gets the end date
此函数没有参数。
Returns null
if the DatePeriod does
not have an end date. For example, when initialized with the
recurrences
parameter, or the
isostr
parameter without an
end date.
Returns a DateTimeImmutable object
when the DatePeriod is initialized with a
DateTimeImmutable object
as the end
parameter.
Returns a cloned DateTime object representing the end date otherwise.
示例 #1 DatePeriod::getEndDate() example
<?php
$period = new DatePeriod(
new DateTime('2016-05-16T00:00:00Z'),
new DateInterval('P1D'),
new DateTime('2016-05-20T00:00:00Z')
);
$start = $period->getEndDate();
echo $start->format(DateTime::ISO8601);
?>
以上例程会输出:
2016-05-20T00:00:00+0000
示例 #2 DatePeriod::getEndDate() without an end date
<?php
$period = new DatePeriod(
new DateTime('2016-05-16T00:00:00Z'),
new DateInterval('P1D'),
7
);
var_dump($period->getEndDate());
?>
以上例程会输出:
NULL
