次の配列を手動で作成しました (下)。簡単に展開できる 2 つの文字列 (explode()) のみを使用してプログラムで作成したいと考えています。

$min_date = '2012-03-01 00:00:00';
$max_date = '2012-04-25 00:00:00';

私はすでに文字列を爆発（）させ、2つの日付の間に何ヶ月あるかを調べました

    $min_date = explode('-',$min_date);
    $min_date['year'] = intval($min_date[0]);
    $min_date['month'] = intval($min_date[1]);
    $min_date['day'] = intval($min_date[2]);

    $max_date = explode('-',$max_date);
    $max_date['year'] = intval($max_date[0]);
    $max_date['month'] = intval($max_date[1]);
    $max_date['day'] = intval($max_date[2]);

$months_between = ($max_date['month'] - $min_date['month']) + 12 * ($max_date['year'] - $min_date['year']);

1を返します

cal_days_in_month()関数も便利なようですが、方法がわかりません...

$days_in_month = cal_days_in_month(CAL_GREGORIAN, $month, $year)

これが私が手動で作成した配列です！

$periods = array(
  '0' => array(
    'month'=>'march',
    'week'=>'1',
    'days'=>'4',
    'readable'=>' Thurs Mar, 01, 2012 - Sun Mar, 04, 2012',
    'created_at_min'=>'2012-03-01 00:00:00',

    'readable'=>' Mon Apr, 2, 2012 - Sun Apr, 8, 2012',
    'created_at_min'=>'2012-04-01 00:00:00',
    'created_at_max'=>'2012-04-08 24:00:00'
  ),
  '7' => array(

    'week'=>'3',
    'days'=>'7',
    'readable'=>' Mon Apr, 9, 2012 - Sun Apr, 15, 2012',

  ),
  '8' => array(
    'month'=>'april',
    'week'=>'4',
    'days'=>'7',
    'readable'=>' Mon Apr, 16, 2012 - Sun Apr, 22, 2012',
    'created_at_min'=>'2012-04-16 00:00:00',
    'created_at_max'=>'2012-04-22 24:00:00'
  ),
  '9' => array(
    'month'=>'april',
    'week'=>'5',
    'days'=>'3',
    'readable'=>' Mon Apr, 23, 2012 - Wed Apr, 25, 2012',
    'created_at_min'=>'2012-04-16 00:00:00',
    'created_at_max'=>'2012-04-25 00:00:00' // note last day timestamp needs to be 00:00:00
  ),
);

これに飛び込む前に、PHPが提供するもので非常に役立つものはありますか?

$weeks = array(
  'may' = array(1,2,3,4,5),
  'april' = array(1,2,3,4,5),
);

このようなことをしてください。次のような配列が得られます。
