重置多维数组中的数组键 [英] Reset array keys in multidimensional array
问题描述
我一直在寻找解决方案,但没有真正成功.我有一个多维数组的父母和孩子,没有深度限制.这是从数据库生成的,但问题是使用我将平面数组排列成多维数组的方式,项目 ID 成为关键,如下所示:
I've been looking around for a solution to this with no real success. I have a multidimensional array of parents and children with no limits on depth. This is generated from a database but the issue is that the item ID becomes the key using my way of arranging a flat array into a multidimensional array like so:
Array(
[28] => Array
(
[id] => 28
[color] => #ff24e5
[name] => Personal
[parent_id] =>
[children] => Array
(
[23] => Array
(
[id] => 23
[color] => #41c3a3
[name] => Shopping
[parent_id] => 28
[children] => Array
(
[22] => Array
(
[id] => 22
[color] => #8be32b
[name] => Deals
[parent_id] => 23
[children] => Array
(
)
)
)
)
[150] => Array
(
[id] => 150
[color] => #e9a3f0
[name] => Orders
[parent_id] => 28
[children] => Array
(
)
)
)
)
)
我想要的是一个执行以下操作的函数:
What I would like, is a function that does the following:
Array (
[0] => Array
(
[id] => 28
[color] => #ff24e5
[name] => Personal
[parent_id] =>
[children] => Array
(
[0] => Array
(
[id] => 23
[color] => #41c3a3
[name] => Shopping
[parent_id] => 28
[children] => Array
(
[0] => Array
(
[id] => 22
[color] => #8be32b
[name] => Deals
[user_id] => 1
[selected] => 0
[parent_id] => 23
[children] => Array
(
)
)
)
)
[1] => Array
(
[id] => 150
[color] => #e9a3f0
[name] => Orders
[parent_id] => 28
[children] => Array
(
)
)
)
)
)
基本上从 0 开始重新分配键.我尝试了很多方法,但我假设我需要找到一个递归解决方案,当我尝试这样做时,它破坏了我的数组.我正在阅读 array_walk_recursive() 函数,但我不太知道除此之外还能做什么.本质上,有没有办法重置多维数组中的数字键?
Essentially reassign keys starting from 0. I've tried numerous methods, but I'm assuming that I need to find a recursive solution and when I tried that, it destroyed my array. I was reading up on the array_walk_recursive() function, but I don't quite know what to do beyond that. Essentially, is there a way to reset numeric keys in a multidimensional array?
感谢您的帮助!
推荐答案
function fix_keys($array) {
foreach ($array as $k => $val) {
if (is_array($val))
$array[$k] = fix_keys($val); //recurse
}
return array_values($array);
}
