如何将一个树状数组转换为一个普通的二维数组
请教如何将一个树状数组转换为一个普通的二维数组
元素的顺序不要紧~~只要是这个结构就行了
例如
Array
(
[0] => Array
(
[kind_id] => 1103
[kind_fid] => 1101
[kind_name] => asdfsadf
[children] => Array
(
[0] => Array
(
[kind_id] => 1109
[kind_fid] => 1103
[kind_name] => testt
[children] => Array
(
)
)
)
)
[1] => Array
(
[kind_id] => 1104
[kind_fid] => 1101
[kind_name] => sdfsdf
[children] => Array
(
[0] => Array
(
[kind_id] => 1110
[kind_fid] => 1104
[kind_name] => test222
[children] => Array
(
)
)
)
)
[2] => Array
(
[kind_id] => 1107
[kind_fid] => 1101
[kind_name] => aaaaaaaa
[children] => Array
(
)
)
)
转为
Array
(
[0] => Array
(
[kind_id] => 1103
[kind_fid] => 1101
[kind_name] => asdfsadf
)
[1] => Array
(
[kind_id] => 1109
[kind_fid] =>1103
[kind_name] => asdfsadf
)
[2] => Array
(
[kind_id] => 1104
[kind_fid] => 1101
[kind_name] => asdfsadf
)
[3] => Array
(
[kind_id] => 1110
[kind_fid] => 1104
[kind_name] => asdfsadf
)
[4] => Array
(
[kind_id] => 1107
[kind_fid] => 1101
[kind_name] => asdfsadf
)
)
[解决办法]
$ar = array (Array
0 =>
array (
'kind_id' => '1103',
'kind_fid' => '1101',
'kind_name' => 'asdfsadf',
'children' =>

'kind_fid' => '1103',

'children' =>

),

array (

array (

'children' =>

),
);
print_r(untree($ar));
function untree($ar) {
$res = array();
foreach($ar as $v) {
$t = $v['children'];
unset($v['children']);
$res[] = $v;
if($t) $res = array_merge($res, untree($t));
}
return $res;
}
[kind_fid] => 1103
