将索引多维数组转换为关联多维数组 [英] convert indexed multidimensional array to associative multidimensional array
本文介绍了将索引多维数组转换为关联多维数组的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个带有嵌套类别的索引数组,如下所示:
I have an indexed array with nested categories like this:
array (
0 =>
array (
'name' => 'Furniture',
'id' => 'b3cdd1k',
'content' =>
array (
0 =>
array (
'name' => 'Tables',
'id' => 'nw24ga3',
'content' =>
array (
0 =>
array (
'name' => 'Wooden tables',
'id' => 'ba5lgaz',
),
1 =>
array (
'name' => 'Glass tables',
'id' => 'rqt91gz',
),
),
),
),
),
1 =>
array (
'name' => 'Lamps',
'id' => 'vb1a4nf',
),
2 =>
array (
'name' => 'Doors',
'id' => 'a5l4gal',
'content' =>
array (
0 =>
array (
'name' => 'Entrance doors',
'id' => 'qwg30fb',
),
),
),
)
是否有优雅的方法将其转换为关联数组(其中键是 id)并保持嵌套结构?
Is there elegant way to convert it to associative array (where keys are id's) and keep nesting structure?
转换后我除了这样的东西:
After conversion I excepting something like this:
array (
'b3cdd1k' =>
array (
'name' => 'Furniture',
'content' =>
array (
'nw24ga3' =>
array (
'name' => 'Tables',
'content' =>
array (
'ba5lgaz' =>
array (
'name' => 'Wooden tables',
),
'rqt91gz' =>
array (
'name' => 'Glass tables',
),
),
),
),
),
'vb1a4nf' =>
array (
'name' => 'Lamps',
),
'a5l4gal' =>
array (
'name' => 'Doors',
'content' =>
array (
'qwg30fb' =>
array (
'name' => 'Entrance doors',
),
),
),
)
推荐答案
你可以试试这个 - 不是最优雅的,但似乎有效:
You could try this - not the most elegant, but seems to work:
function convert(&$a)
{
$result = Array();
foreach($a as $k=>&$v)
{
$result[$v['id']]['name'] = $v['name'];
if(is_array($v['content'])) $result[$v['id']]['content'] = convert($v['content']);
}
return $result;
}
if(count($array) != 0) $result = convert($array);
