Description:
------------
I use an object {DateTime} for mass generation intervals in the database. When generating discovered
a serious error. By moving the dates in 1 month I have not received February 2017
Test script:
---------------
$lastDate = new DateTime();
$lastDate->sub(new DateInterval("P1M"));
$generateToThisDate = new DateTime();
$generateToThisDate->add(new DateInterval("P20M"));
while ($lastDate < $generateToThisDate) {
$lastDate->add(new DateInterval("P1M"));
echo $lastDate->format('Y-m-01') . " - " .
$lastDate->format('Y-m-t') . "\n";
}
Expected result:
