我有一个带子项的输入类别数组，如下所示
我想使用递归函数将其转换为另一个数组，如
['1'=＆gt;'时尚'，'10'=＆gt; '时尚＆gt;妇女”， '23'=＆GT; '时尚＆gt;女人＆gt;服装”， '29'=＆GT; '时尚＆gt;女人＆gt;服装＆gt;连衣裙......等等]
我的目的是使用输出数组填充选择框选项以添加类别。
阵 （ [1] =＆gt;排列 （ [id] =＆gt; 1 [name] =＆gt;时尚 [parent_id] =＆gt; 0 [孩子] =＆gt;排列 （ [10] =＆gt;排列 （ [id] =＆gt; 10 [name] =＆gt;妇女 [parent_id] =＆gt; 1 [孩子] =＆gt;排列 （ [23] =＆gt;排列 （ [id] =＆gt; 23 [name] =＆gt;服装 [parent_id] =＆gt; 10 [孩子] =＆gt;排列 （ [29] =＆gt;排列 （ [id] =＆gt; 29 [name] =＆gt;礼服 [parent_id] =＆gt; 23 [孩子] =＆gt;排列 （ ）

答案 0 :(得分：0)
您可以通过以下方式创建数组：
$array = array(
'category_1' => 'value',
'category_2' => array(
'subcategory_1' => 'value',
'subcategory_2' => 'value',
),
);
