不希望的自动递增分钟

Question

The Code:

$months = array("January", "February" .......); // Up to December
foreach ($months As $month) {
  $date_ranges_from[] = date('F d, Y H:m:s', strtotime("$month 1 midnight"));
}
print_r($date_ranges_from);

The Undesired output:

// Notice that the minutes are auto-incremented
Array
(
 [0] => January 01, 2015 00:01:00
 [1] => February 01, 2015 00:02:00
 [2] => March 01, 2015 00:03:00
 [3] => April 01, 2015 00:04:00
 [4] => May 01, 2015 00:05:00
 [5] => June 01, 2015 00:06:00
 [6] => July 01, 2015 00:07:00
 [7] => August 01, 2015 00:08:00
 [8] => September 01, 2015 00:09:00
 [9] => October 01, 2015 00:10:00
 [10] => November 01, 2015 00:11:00
 [11] => December 01, 2015 00:12:00
)

The Desired output:

// The time should always be 00:00:00
Array
(
 [0] => January 01, 2015 00:00:00
 [1] => February 01, 2015 00:00:00
 [2] => March 01, 2015 00:00:00
 [3] => April 01, 2015 00:00:00
 [4] => May 01, 2015 00:00:00
 [5] => June 01, 2015 00:00:00
 [6] => July 01, 2015 00:00:00
 [7] => August 01, 2015 00:00:00
 [8] => September 01, 2015 00:00:00
 [9] => October 01, 2015 00:00:00
 [10] => November 01, 2015 00:00:00
 [11] => December 01, 2015 00:00:00
)

The problem: I don't know why the minutes gets also incremented when I statically put it as midnight. Any help would be appreciated thanks.

Answer 1

Cause You were incrementing month with each loop H:m:s which should be H:i:s

Within php date function m stands for month and i for minutes

$date_ranges_from[] = date('F d, Y H:m:s', strtotime("$month 1 midnight"));
                                  //^^ m stands for month

should be

$date_ranges_from[] = date('F d, Y H:i:s', strtotime("$month 1 midnight"));
                                  //^^ i stands for minutes
