Question

我有这两个2D维数组，

的 $ ARRAY1

Array(
 'week1' => Array (
              0 => '2015-06-29',
              1 => '2015-06-30',
            )
)

$数组2

Array(
 'week1' => Array (
              0 => '2015-07-01',
              1 => '2015-07-02',
              2 => '2015-07-03',
              3 => '2015-07-04',
              4 => '2015-07-05',
            ),
 'week2' => Array (
              0 => '2015-07-06',
              1 => '2015-07-07',
              2 => '2015-07-08',
              3 => '2015-07-09',
              4 => '2015-07-10',
              5 => '2015-07-11',
              6 => '2015-07-12',
            ),
)

这是我的预期结果，

Array(
 'week1' => Array (
              0 => '2015-06-29',
              1 => '2015-06-30',
              2 => '2015-07-01',
              3 => '2015-07-02',
              4 => '2015-07-03',
              5 => '2015-07-04',
              6 => '2015-07-05',
            ),
 'week2' => Array (
              0 => '2015-07-06',
              1 => '2015-07-07',
              2 => '2015-07-08',
              3 => '2015-07-09',
              4 => '2015-07-10',
              5 => '2015-07-11',
              6 => '2015-07-12',
            ),
)

我一直在尝试使用array_push，但数组变为3维而不是加入相同的键名。你们可以叫我出去吗？提前致谢。：d

Answer 1

我认为你可以使用array_merge_recursive（http://php.net/manual/en/function.array-merge-recursive.php）

只需：

array_merge_recursive($array1, $array2)

Answer 2

只需循环遍历您要添加的数组并使用数组array_merge()的键，例如

foreach($array1 as $k => $v)
    $array2[$k] = array_merge($array2[$k], $v);

PHP将数组推入spessific键
