變換平面數組多維與節點值

Question

我有一個數組，看起來像這樣（改變食物的例子 - 它實際上是業務主題標籤的分類）：

Array 
(
    [fruit] => Fruit 
    [fruit/apple] => Apple 
    [fruit/banana] => Banana 
    [fruit/passion-fruit] => Passion fruit 
    [vegetable] => Vegetable 
    [vegetable/beans] => Beans 
    [vegetable/beans/runner-beans] => Runner beans   
) 

我想使用遞歸（推測）將其改爲：

Array 
(
    [fruit] => Array 
     (
      [title] => Fruit 
      [children] => Array 
       (
        [apple] => Array 
         (
          [title] => Apple 
         ) 
        [banana] => Array 
         (
          [title] => Banana 
         ) 
        [passion-fruit] => Array 
         (
          [title] => Passion fruit 
         ) 
       ) 
     ) 
    [vegetable] => Array 
     (
      [title] => Vegetable 
      [children] => Array 
       (
        [beans] => Array 
         (
          [title] => Beans 
          [children] => Array 
           (
            [runner-beans] => Array 
             (
              [title] => Runner beans 
             ) 
           ) 
         ) 
       ) 
     ) 
) 

我不知道該怎麼做。我在這裏找到了其他的例子，用於將平展數組轉換爲多維數組，但不包括有值（'標題'）和自定義子節點的地方。提前感謝任何指針。

假設你的數組被命名爲$array：

$result = array(); 

foreach($array as $key => $value) { 
    $temp =& $result; 
    $path = explode('/', $key); 

    foreach($path as $subkey) { 
     if(!isset($temp[$subkey])) { 
      $temp[$subkey]['title'] = $value; 
      $temp[$subkey]['children'] = array(); 
     } 
     $temp =& $temp[$subkey]['children']; 
    } 
} 

我張貼此，即使它產生，即使沒有孩子children關鍵。我將重新審視和編輯。
