PHP - 獲得array_values重新索引嵌套數組

Question

我已經尋找了一段時間了一個解決方案，但似乎無法得到一個工作。我有一個多維數組，並且能夠成功地使用array_values()將重新索引爲0的「父」數組項目（它們被索引爲1，JSON將它當作一個對象而不是數組對待）。但是，嵌套數組需要從0重新索引，我似乎無法得到它的工作。這就是我目前正在與array_values($arr)接收：

array (
    0 => 
    array (
    'navigationMenuId' => '1', 
    'parentNavigationMenuId' => '0', 
    'contentId' => '1', 
    'fullURL' => '/index', 
    'contentSlug' => 'index', 
    'contentAlias' => 'Index', 
    'navigationAnchor' => 'Home', 
    'navigationOrder' => '1', 
    'subNavigationItems' => 
    array (
    ), 
), 
    1 => 
    array (
    'navigationMenuId' => '2', 
    'parentNavigationMenuId' => '0', 
    'contentId' => '15', 
    'fullURL' => '/top-nav-1/index', 
    'contentSlug' => 'index', 
    'contentAlias' => 'Index', 
    'navigationAnchor' => 'Top Nav 1', 
    'navigationOrder' => '2', 
    'subNavigationItems' => 
    array (
    ), 
), 
    2 => 
    array (
    'navigationMenuId' => '3', 
    'parentNavigationMenuId' => '0', 
    'contentId' => '7', 
    'fullURL' => '/top-nav-2/index', 
    'contentSlug' => 'index', 
    'contentAlias' => 'Index', 
    'navigationAnchor' => 'Top Nav 2', 
    'navigationOrder' => '3', 
    'subNavigationItems' => 
    array (
     4 => 
     array (
     'navigationMenuId' => '4', 
     'parentNavigationMenuId' => '3', 
     'contentId' => '8', 
     'fullURL' => '/top-nav-2/sub-nav-1', 
     'contentSlug' => 'sub-nav-1', 
     'contentAlias' => 'Sub Nav 1', 
     'navigationAnchor' => 'Sub Nav 1', 
     'navigationOrder' => '1', 
     'subNavigationItems' => 
     array (
     ), 
    ), 
     5 => 
     array (
     'navigationMenuId' => '5', 
     'parentNavigationMenuId' => '3', 
     'contentId' => '10', 
     'fullURL' => '/top-nav-2/sub-nav-2', 
     'contentSlug' => 'sub-nav-2', 
     'contentAlias' => 'Sub Nav 2', 
     'navigationAnchor' => 'Sub Nav 2', 
     'navigationOrder' => '2', 
     'subNavigationItems' => 
     array (
     ), 
    ), 
     6 => 
     array (
     'navigationMenuId' => '6', 
     'parentNavigationMenuId' => '3', 
     'contentId' => '9', 
     'fullURL' => '/top-nav-2/sub-nav-3', 
     'contentSlug' => 'sub-nav-3', 
     'contentAlias' => 'Sub Nav 3', 
     'navigationAnchor' => 'Sub Nav 3', 
     'navigationOrder' => '3', 
     'subNavigationItems' => 
     array (
     ), 
    ), 
     7 => 
     array (
     'navigationMenuId' => '7', 
     'parentNavigationMenuId' => '3', 
     'contentId' => '11', 
     'fullURL' => '/top-nav-2/sub-nav-4', 
     'contentSlug' => 'sub-nav-4', 
     'contentAlias' => 'Sub Nav 4', 
     'navigationAnchor' => 'Sub Nav 4', 
     'navigationOrder' => '4', 
     'subNavigationItems' => 
     array (
     ), 
    ), 
    ), 
), 
    3 => 
    array (
    'navigationMenuId' => '8', 
    'parentNavigationMenuId' => '0', 
    'contentId' => '5', 
    'fullURL' => '/top-nav-3/index', 
    'contentSlug' => 'index', 
    'contentAlias' => 'Top Nav 3', 
    'navigationAnchor' => 'Top Nav 3', 
    'navigationOrder' => '4', 
    'subNavigationItems' => 
    array (
    ), 
), 
    4 => 
    array (
    'navigationMenuId' => '9', 
    'parentNavigationMenuId' => '0', 
    'contentId' => '6', 
    'fullURL' => '/top-nav-4/index', 
    'contentSlug' => 'index', 
    'contentAlias' => 'Top Nav 4', 
    'navigationAnchor' => 'Top Nav 4', 
    'navigationOrder' => '5', 
    'subNavigationItems' => 
    array (
     10 => 
     array (
     'navigationMenuId' => '10', 
     'parentNavigationMenuId' => '9', 
     'contentId' => '12', 
     'fullURL' => '/top-nav-4/sub-nav-1', 
     'contentSlug' => 'sub-nav-1', 
     'contentAlias' => 'Sub Nav 1', 
     'navigationAnchor' => 'Sub Nav 1', 
     'navigationOrder' => '1', 
     'subNavigationItems' => 
     array (
     ), 
    ), 
     11 => 
     array (
     'navigationMenuId' => '11', 
     'parentNavigationMenuId' => '9', 
     'contentId' => '13', 
     'fullURL' => '/top-nav-4/sub-nav-2', 
     'contentSlug' => 'sub-nav-2', 
     'contentAlias' => 'Sub Nav 2', 
     'navigationAnchor' => 'Sub Nav 2', 
     'navigationOrder' => '2', 
     'subNavigationItems' => 
     array (
     ), 
    ), 
     12 => 
     array (
     'navigationMenuId' => '12', 
     'parentNavigationMenuId' => '9', 
     'contentId' => '14', 
     'fullURL' => '/top-nav-4/sub-nav-3', 
     'contentSlug' => 'sub-nav-3', 
     'contentAlias' => 'Sub Nav 3', 
     'navigationAnchor' => 'Sub Nav 3', 
     'navigationOrder' => '3', 
     'subNavigationItems' => 
     array (
     ), 
    ), 
    ), 
), 
    5 => 
    array (
    'navigationMenuId' => '13', 
    'parentNavigationMenuId' => '0', 
    'contentId' => '4', 
    'fullURL' => '/top-nav-5/index', 
    'contentSlug' => 'index', 
    'contentAlias' => 'Top Nav 5', 
    'navigationAnchor' => 'Top Nav 5', 
    'navigationOrder' => '6', 
    'subNavigationItems' => 
    array (
    ), 
), 
) 

通知第一嵌套數組索引如何4，5，6，和7，和第二個的索引是10，11，和12我需要它們都從0開始。如果這樣做的函數可以是無限遞歸函數，那也是非常好的。如果你看到每一個項目都有一個subNavigationItems數組，可能會被更多的東西填充，我也需要這些數組重新索引爲0。

我如何能做到這一點有什麼想法？

使用本

<?php 

    function reOrderArray($array) { 
     if(! is_array($array)) { 
      return $array; 
     } 
     $count = 0; 
     $result = array(); 
     foreach($array as $k => $v) { 
      if(is_integer_value($k)) { 
       $result[$count] = reOrderArray($v); 
       ++$count; 
      } else { 
       $result[$k] = reOrderArray($v); 
      } 
     } 
     return $result; 
    } 

    public function is_integer_value($value) { 
     if(!is_int($value)) { 
      if(is_string($value) && preg_match("/^-?\d+$/i",$value)) { 
       return true; 
      } 
      return false; 
     } 
     return true; 
    } 

Answer 2

我想這應該這樣做：

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; 
    } 
} 

它不遞歸到對象中，只有子陣列。
