Thanks for the article, and thanks pcguru for the comment. I couldn’t work out how to add hours but now I see
$d->add(new DateInterval(‘PT2H’));

Thanks for the helpful article. It got me unstuck (for now, anyway :) ).

Here’s an simple example of using DateTime, DateInterval, and DatePeriod together:

$dt = new DateTime();
$interval = new DateInterval(‘P1M’);
$period = new DatePeriod($dt, $interval, 12);
foreach ($period as $each) {
echo $each->format(‘Y-m-d’) . ”;
}

Scrap that comment, it works fine.

$finished->add(new DateInterval(‘PT’.$secondsToGo.’S'));

Nice to find some information on these classes!

They are really hard to work with right now, not only because of the lack of docs.

For example in my app I have an interval calculated in seconds, that I need to add to a DateTime object. But I can’t create a DateInterval from seconds, I have to split those seconds into minutes, hours, days etc to form a valid interval string. Ouch.

I hope they continue to evolve.
