范例

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:

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?
