配列に含まれる時間間隔に基づいて配列を分割する方法を探しています。たとえば、

Array (
   [0] => Array (
               ['type'] => Text Format
               ['interval'] => 30
               ['init'] => 2012-04-30 09:00:00
               ['final'] => 2012-04-30 10:00:00
           )
   [1] => Array (
               ['type'] => Word Format
               ['interval'] => 12
               ['init'] => 2012-04-28 13:00:00
               ['final'] => 2012-04-28 13:30:00
           )
)

に分割します：

Array (
   [0] => Array (
               ['type'] => Text Format
               ['interval'] => 30
               ['init'] => 2012-04-30 09:00:00
               ['final'] => 2012-04-30 09:30:00
           )
   [1] => Array (
               ['type'] => Text Format
               ['interval'] => 30
               ['init'] => 2012-04-30 09:30:00
               ['final'] => 2012-04-30 10:00:00
           )
   [2] => Array (
               ['type'] => Word Format
               ['interval'] => 12
               ['init'] => 2012-04-28 13:00:00
               ['final'] => 2012-04-28 13:12:00
           )
   [3] => Array (
               ['type'] => Word Format
               ['interval'] => 12
               ['init'] => 2012-04-28 13:12:00
               ['final'] => 2012-04-28 13:24:00
           )
)

これを行うための良い方法は何でしょうか？

あなたが提供したものを考えると、これはそれを行う必要があります：

foreach($old as $o) {
    $interval= $o['interval'];
    $new[] = $o;
    $x = count($new)-1;
    $new[$x]['final'] = date("Y-m-d H:i:s",strtotime("+$interval minutes", strtotime($old[$x]['init'])));

    $new[] = $o;
    $y = count($new)-1;
    $new[$y]['init'] = $new[$x]['final'];
    $new[$y]['final']   = date("Y-m-d H:i:s",strtotime("+$interval minutes", strtotime($new[$y]['init'])));
}

echo "Old:<pre>".print_r($old,true)."</pre>";
echo "New<pre>".print_r($new,true)."</pre>";

私のテストした出力：

Old:

    [0] => Array
        (
            [type] => Text Format
            [interval] => 30
            [init] => 2012-04-30 09:00:00
            [final] => 2012-04-30 10:00:00
        )

    [1] => Array
        (
            [type] => Word Format
            [interval] => 12
            [init] => 2012-04-28 13:00:00
            [final] => 2012-04-28 13:30:00

あなたを正しい軌道に乗せるためのいくつかのこと：

  1. PHPで日付/時刻文字列を直接比較したり、タイムスタンプに変換したりすることはできません

  2. initとfinalを比較し、差が>intervalかどうかを確認します

  3. 差<=間隔の場合、これで完了です

  4. 差>間隔の場合は、新しい配列を作成し、initに間隔を追加します。手順2に進みます

コードを見せてください！

これはあなたのために働くかもしれません...最大20の間隔と比較しているだけです

$dates = Array (
        0 => Array (
                'type' => "Text Format",
                'interval' => "30",
                'init' => "2012-04-30 09:00:00",
                'final' => "2012-04-30 10:00:00" 
        ),
        1 => Array (
                'type' => "Word Format",
                'interval' => 12,
                'init' => "2012-04-28 13:00:00",
                'final' => "2012-04-28 13:30:00" 
        ) 
);

echo "<pre>";

$output = array ();

foreach ( $dates as $key => $value ) {
    makeDates ( $value ['init'], $value ['final'], $value ['interval'], $value ['type'] ,$output);
}

var_dump ( $output );
function makeDates($start, $end, $min, $type, &$output) {
    $start = new DateTime ( $start );
    $end = new DateTime ( $end );

    $interval = new DateInterval ( 'PT' . $min . 'M' );

    for($i = 0; $i < 20; $i ++) {
        $list = array ();
        $list ['type'] = $type;
        $list ['interval'] = $min;
        $list ['init'] = $start->format ( 'Y-m-d H:i:s' );

        $start->add ( $interval );

        $list ['final'] = $start->format ( 'Y-m-d H:i:s' );

        if ($start == $end) {
            $output [] = $list;
        }

        if ($start >= $end) {
            break;
        }

        $output [] = $list;

    }

    return $output;
}
