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.
Example #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
Example #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
