I found two things useful to know that aren't covered here.
1. endDate is excluded:
<?php
$i = new DateInterval('P1D');
$d1 = new Datetime();
$d2 = clone $d1; $d2->add($i);
foreach(new DatePeriod($d1, $i, $d2) as $d) {
echo $d->format('Y-m-d H:i:s') . "\n";
}
?>
Will output:
2010-11-03 12:39:53
(Another one because I got it wrong at first)
2. For the first form, recurrences really means REcurrences, not occurences.
<?php
$i = new DateInterval('P1D');
$d = new Datetime();
foreach(new DatePeriod($d, $i, 1) as $d) {
echo $d->format('Y-m-d H:i:s') . "\n";
}
?>
Will output:
2010-11-03 12:41:05
2010-11-04 12:41:05

Exemplos
Exemplo #1 Exemplos de DatePeriod
<?php
$start = new DateTime('2012-07-01');
$interval = new DateInterval('P7D');
$end = new DateTime('2012-07-31');
$recurrences = 4;
$iso = 'R4/2012-07-01T00:00:00Z/P7D';
// All of these periods are equivalent.
$period = new DatePeriod($start, $interval, $recurrences);
$period = new DatePeriod($start, $interval, $end);
$period = new DatePeriod($iso);
// By iterating over the DatePeriod object, all of the
// recurring dates within that period are printed.
foreach ($period as $date) {
echo $date->format('Y-m-d')."\n";
}
?>
O exemplo acima irá imprimir:
2012-07-01 2012-07-08 2012-07-15 2012-07-22 2012-07-29
Exemplo #2 Exemplo de DatePeriod com DatePeriod::EXCLUDE_START_DATE
<?php
$start = new DateTime('2012-07-01');
$interval = new DateInterval('P7D');
$end = new DateTime('2012-07-31');
$period = new DatePeriod($start, $interval, $end,
DatePeriod::EXCLUDE_START_DATE);
// By iterating over the DatePeriod object, all of the
// recurring dates within that period are printed.
// Note that, in this case, 2012-07-01 is not printed.
foreach ($period as $date) {
echo $date->format('Y-m-d')."\n";
}
?>
O exemplo acima irá imprimir:
2012-07-08 2012-07-15 2012-07-22 2012-07-29

When you add the time 23:59:59 to the end DateTime object something like the following then the end date will be included in the period:
<?php
$date_start = new DateTime('2012-03-12');
$date_end = new DateTime('2012-03-22 23:59:59');
$interval = '+2 days';
$date_interval = DateInterval::createFromDateString($interval);
$period = new DatePeriod($date_start, $date_interval, $date_end, DatePeriod::EXCLUDE_START_DATE);
foreach($period as $dt) {
echo $dt->format('d/m');
}
?>
OUTPUT:
14/03
16/03
18/03
20/03
22/03

The parameter isostr should accept an ISO 8601 format, but doing this is not work :
<?php
$dateStart = date_create('first day of next month this year');
$isoStr = $dateStart ->format(DateTimeInterface::ISO8601);
$datePeriod = new DatePeriod("R10/{$isoStr}/P1M");
// Throw Exception : DatePeriod::__construct(): Unknown or bad format (R10/2020-02-01T22:52:26+0000Z/P1M)
// While doing it by this way works
$datePeriod = new DatePeriod($dateStart , \DateInterval::createFromDateString("+1 month"), 10);
?>
