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
