Question

I saw this code on a forum:

 $begin = new DateTime( $start_date );
    $end = new DateTime(date("Y-m-d",strtotime("+1 day", strtotime($end_date))));
    while($begin < $end) {
        $period[] = $begin->format('Y-m-d');
        $begin->modify('+1 day');
    }

I want to do exactly what the OP was asking i.e. create a date interval of 1 day without using DateInterval class as I am not using PHP 5.3 (I’m using 5.2)

However when I try to use the $period array I get an error:

Undefined variable: period

This is my code:

    $start = new DateTime("09-09-2011");
    $end   = new DateTime("24-09-2011");

         while($start < $end) {

        $period[] = $start->format('Y-m-d');
        $start->modify('+1 day');

        }

print_r($period) //error - undefined variable

Why does it not work – is it to do with putting a datetime object in a while loop?

Answer 1

so define it easily

$period = array();

however, this will never go to that while loop = this code is not useful
