Negative DateInterval

Question

I want to create a DatePeriod object with a negative DateInterval.

This creates a DatePeriod with the year increasing from today to 2016.

$this->S         


        

Answer 1

This extract worked for me:

    $iDate = $endDate;
    while($iDate >= $startDate) {
        $dates[] = new DateTime($iDate->format('Y-m-d'));
        $iDate->sub(new DateInterval("P1D"));
    }
