\[我正在使用WordPress REST API来获取系统中的类别列表，其中包括层次结构数据，但是到目前为止，我仍无法找出将这些数据转换为关联数组的一种干净方法。

我拥有的数据看起来像这样(JSON)：\[

此数据是通过WordPress函数get\_terms(array('orderby' => 'parent'))获得的。

我的目标是最终将其作为层次结构返回，从带有"parent": 0的那些条目开始，然后向下直到"is\_parent"为false的对象。

我尝试仅加载parent = 0的类别，然后为每个加载其子项，然后为每个加载那些子项，依此类推，这也许可行，但我不知道一种动态递归的干净方法，用这种方式建立一个数组。

我也尝试加载所有类别，然后尝试通过array\_filter和array\_map对它们进行排序，但是我也找不到一种很好的方法来确保遍历每个层次结构级别的每个父级的所有子级。

我现在想到了尝试从所有这些数据构建一个关联数组的想法，从"parent": 0开始(固定)，然后向下遍历，但是我有\[\[no idea从哪里开始。我已经看到一些有关array\_walk\_recursive的信息，但是在这种情况下可以使用吗？此数据的最终表示应如下所示：

0: \[

445: \[

447: \[

448: \{

...no longer a parent here...

\},

455: \{

...also no longer a parent...

\],

450: \[

...

\],

641: \[

...

\}之所以需要这种格式，是因为我希望将其轻松显示为网页中的层次结构菜单。从后端以这种格式返回它会减少前端的工作量。

这可能吗？如果是这样，我该怎么办？
