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
         )

)
