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;}
