2 次元配列の 2 つのセットがあり、1 つの 2 次元配列にマージしたい。しかし、各配列の要素数は同じではなく、最初の2つの要素は同じであり、複製したくありません。ここにあります。

最初の 2 次元配列:

Array(   
       [0] => Array
           (
              [0] => 25/2/2013
              [1] => 8.45 a.m
              [2] => 9.98
           )

       [1] => Array
           (
              [0] => 25/2/2013
              [1] => 8.46 a.m
              [2] => 9.02
           )
     )

2 番目の 2 次元配列:

 Array(   
        [0] => Array
            (
                [0] => 25/2/2013
                [1] => 8.45 a.m
                [2] => 1.23
                [3] => 6.1
            )

        [1] => Array
            (
                [0] => 25/2/2013
                [1] => 8.46 a.m
                [2] => 1.75
                [3] => 1.75
            )
      )

このように結果を得るにはどうすればよいですか:

Array(   
        [0] => Array
            (
                [0] => 25/2/2013
                [1] => 8.45 a.m
                [2] => 9.98
                [3] => 1.23
                [4] => 6.1
            )

        [1] => Array
            (
                [0] => 25/2/2013
                [1] => 8.46 a.m
                [2] => 9.02
                [3] => 1.75
                [4] => 1.75
            )
     )

最初の配列の var export は次のとおりです。

( 0 => array ( 0 => '5/2/2013', 1 => '9:31:00 AM', 2 => '0.395', 3 => '0.395', 4 => '302.855', 5 => '0.563', ), 1 => array ( 0 => '5/2/2013', 1 => '9:33:00 AM', 2 => '0.383', 3 => '0.383', 4 => '303.431', 5 => '0.563', )

2 番目の配列の場合:

( 0 => array ( 0 => '5/2/2013', 1 => '9:31:00 AM', 2 => '-1.000', 3 => '-1.000', 4 => '-1.000', 5 => '-1.670', 6 => '-1.000', 7 => '-11.000', ), 1 => array ( 0 => '5/2/2013', 1 => '9:33:00 AM', 2 => '-1.000', 3 => '-1.000', 4 => '-1.000', 5 => '-1.670', 6 => '-1.000', 7 => '-11.000', )

使用array_merge_recursive例

$array = array_merge_recursive($array1, $array2);
 var_dump($array);

両方の配列が同じ順序である場合、コードは非常に簡単です。

$a = array(
    array('5/2/2013', '9:31:00 AM', '0.395', '0.395', '302.855', '0.563'),
    array('5/2/2013', '9:33:00 AM', '0.383', '0.383', '303.431', '0.563'),
);

$b = array(
    array('5/2/2013', '9:31:00 AM', '-1.000', '-1.000', '-1.000', '-1.670', '-1.000', '-11.000'),
    array('5/2/2013', '9:33:00 AM', '-1.000', '-1.000', '-1.000', '-1.670', '-1.000', '-11.000'),
);


$i = new MultipleIterator(MultipleIterator::MIT_NEED_ALL | MultipleIterator::MIT_KEYS_ASSOC);
$i->attachIterator(new ArrayIterator($a), 'a');
$i->attachIterator(new ArrayIterator($b), 'b');

$result = [];
foreach ($i as $v) {
    $result[] = array_merge($v['a'], array_slice($v['b'], 2));
}
print_r($result);

基本的に、両方の配列を同時に反復処理し、各要素について、最初の配列と 2 番目の配列をマージして最終的な配列を作成します (共通部分をスキップします)。

結果：

Array
(
    [0] => Array
        (
            [0] => 5/2/2013
            [1] => 9:31:00 AM
            [2] => 0.395
            [3] => 0.395
            [4] => 302.855
            [5] => 0.563
            [6] => -1.000
            [7] => -1.000
            [8] => -1.000
            [9] => -1.670
            [10] => -1.000
            [11] => -11.000
        )

    [1] => Array
        (
            [0] => 5/2/2013
            [1] => 9:33:00 AM
            [2] => 0.383
            [3] => 0.383
            [4] => 303.431
            [5] => 0.563
            [6] => -1.000
            [7] => -1.000
            [8] => -1.000
            [9] => -1.670
            [10] => -1.000
            [11] => -11.000
        )
