How to Loop Between Two Dates in PHP

The problem was simple enough, I wanted to loop over all the days between two dates, taking a new month or year into account and rolling over automatically.

Luckily there is a way loop between two dates in PHP which is actually pretty simple and uses a while loop.

date_default_timezone_set('UTC');

$start_date = '2010-01-01';
$end_date = '2010-03-15';

while (strtotime($start_date) <= strtotime($end_date)) {
    echo "$start_daten";
    $start_date = date ("Y-m-d", strtotime("+1 days", strtotime($start_date)));
}

You can adjust to +1 days to +2 days for every other day, or +1 week for every week between two dates.
