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
)
)
回复讨论(解决方案)
$ar = array ( 0 => array ( 'kind_id' => '1103', 'kind_fid' => '1101', 'kind_name' => 'asdfsadf', 'children' => array ( 0 => array ( 'kind_id' => '1109', 'kind_fid' => '1103', 'kind_name' => 'testt', 'children' => array ( ), ), ), ), 1 => array ( 'kind_id' => '1104', 'kind_fid' => '1101', 'kind_name' => 'sdfsdf', 'children' => array ( 0 => array ( 'kind_id' => '1110', 'kind_fid' => '1104', 'kind_name' => 'test222', 'children' => array ( ), ), ), ), 2 => array ( 'kind_id' => '1107', 'kind_fid' => '1101', 'kind_name' => 'aaaaaaaa', 'children' => array ( ), ),);print_r(untree($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;}Array (
[0] => Array
(
[kind_id] => 1103
[kind_fid] => 1101
[kind_name] => asdfsadf
)
[1] => Array
(
[kind_id] => 1109
[kind_fid] => 1103
[kind_name] => testt
)
[2] => Array
