Question

How to get last day of each month within a date range in PHP?

Input:

$startdate = ‘2013-01-15’
$enddate = ‘2013-03-15’

The output that I want is:

2013-01-31 End date of January
2013-02-28 End date of February
2013-03-15 *End date of March is ‘2013-03-31’ but the end date is ‘2013-03-15’ .

So I want 2013-03-15.

How can I do that?

Answer 1

function get_months($date1, $date2) {

    $time1 = strtotime($date1);
    $time2 = strtotime($date2);

    $my = date('mY', $time2);
    $months = array(date('Y-m-t', $time1));
    $f = '';

    while($time1 < $time2) {
        $time1 = strtotime((date('Y-m-d', $time1).' +15days'));

        if(date('F', $time1) != $f) {
            $f = date('F', $time1);

            if(date('mY', $time1) != $my && ($time1 < $time2))
                $months[] = date('Y-m-t', $time1);
        }

    }

    $months[] = date('Y-m-d', $time2);
    return $months;
}

$myDates = get_months('2005-01-20', '2005-11-25');

$myDates will have the output you want. It will work even if years are different. Logic is from this URL
