Question

for($i=0; $i<4; $i++)
{

 $monthArr[] = date("Y-m-d H:i:s", strtotime('2011-10-31'. -1*$i.' month'));

 }

Result:

Array
(
    [0] => 2011-10-31
    [1] => 2011-10-01    //Here should be 2011-09-30
    [2] => 2011-08-31
    [3] => 2011-07-31
)

I would like the output like the following, Thanks!

Array
(
    [0] => 2011-10-31
    [1] => 2011-09-30
    [2] => 2011-08-31
    [3] => 2011-07-31
)

Answer 1

$days_past = 0;    
for($i=0; $i<4; $i++) {
    $monthArr[] = date("Y-m-d H:i:s", strtotime('2011-10-31 '.$days_past.' days'));
    $days_past -= cal_days_in_month(CAL_GREGORIAN, 10 - $i, 2011);
}

• 0 days
• 31 days
• 61 days
  etc.
