私は多次元配列を持っており、array_values().

ただし、subNavigationItemsサブアレイのインデックスも再作成する必要があります。

これは私が現在受け取っているものですarray_values($arr)：

array (
  0 => 
  array (
    'navigationMenuId' => '1',
    'parentNavigationMenuId' => '0',
    'contentId' => '1',

    'contentSlug' => 'index',
    'contentAlias' => 'Index',
    'navigationAnchor' => 'Home',
    'navigationOrder' => '1',
    'subNavigationItems' => 
    array (
    ),
  ),
  1 => 
  array (

  ),
)

最初のネストされた配列インデックスが 4、5、6、および 7 であり、2 番目のインデックスが 10、11、および 12 であることに注意してください。両方とも 0 から開始する必要があります。 do this は無限再帰関数にすることができます。

すべての単一のアイテムに、subNavigationItemsより多くのもので埋められる可能性のある配列があり、それらの配列も 0 で再インデックスする必要があります。

これを達成する方法について何か考えはありますか？

私はこれがそれを行うべきだと思います:

function reindex_array_recursive($array) {
    if (is_array($array)) {
        if (array_keys($array) === range(0, count($array) - 1)) { // Indexed array
            return array_values(array_map('reindex_array_recursive', $array));
        } else { // Associative array
            foreach ($array as $value) {
                $value = reindex_array_recursively($value);
            }
            return $array;
        }
    } else {
        return $array;
    }
}

オブジェクトには再帰せず、サブ配列のみに再帰します。
