希望有人能帮忙。我有一个无限数组，这意味着我可以继续向它添加子数组
类别1>子类别1>etc>etc类别1>子类别2>etc>etc
类别2>子类别1>etc>etc类别2>子类别2>etc>etc
以我目前的数据结构，这可能吗？！谢谢
Array
(
[Category 1] => Array
(
[title] => Category 1
[id] => 1
[parentID] => 0
[children] => Array
(
[0] => Array
(
[title] => Child of Category 1
[id] => 3
[parentID] => 1
[children] => Array
(
)
)
[1] => Array
(
[title] => Child of Category 1
[id] => 4
[parentID] => 1
[children] => Array
(
)
)
)
)
[Category 2] => Array
(
[title] => Category 2
[id] => 2
[parentID] => 0
[children] => Array
(
[0] => Array
(
[title] => Child of Category 2
[id] => 5
[parentID] => 2
[children] => Array
(
)
)
[1] => Array
(
[title] => Child of Category 2
[id] => 6
[parentID] => 2
[children] => Array
(
)
)
)
)
)
就像estshy说的，是的，你可以做到。
我冒昧地为你试了一下，并且能够解决你的问题。
