Bug #78055 [NEW]: DatePeriod recurrences changing after creation
From: kb2kztynisv99h3ykx at mail dot uebernickel dot info
Operating system: macOS
PHP version: 7.3.5
Package: Date/time related
Bug Type: Bug
Bug description:DatePeriod recurrences changing after creation
Description:
------------
When creating a DatePeriod object using the "recurrences" constructor,
it internally changes the counter by increasing it by 1.
As the test script illustrates the expectation would be to have the
given count of iterations, but it actually contains one more.
The documentation at https://www.php.net/manual/en/class.dateperiod.php
misses the details. My guess is some relation to the "include start
date" option.
Test script:
---------------
<?php
$start = new DateTime('2018-12-31 00:00:00');
$interval = new DateInterval('P1M');
$recurrences = 5;
$period = new DatePeriod($start, $interval, $recurrences);
$dates = iterator_to_array($period);
assert($recurrences === $period->recurrences, 'The recurrences should
match.');
assert($recurrences === count($dates), 'The iterator count should match
the recurrences.');
var_dump(array_map(function(DateTime $date) {
return $date->format('Y-m-d');
}, iterator_to_array($period)));
Expected result:
----------------
My expectation would be to have 5 dates even when including the start
date.
Actual result:
--------------
The actual result are 6 dates within the iterator.
