源数据如下。

<code>Array
(
    [id] => 1
    [level] => CEO
    [children] => Array
        (
            [id] => 2
            [level] => CTO
            [children] => Array
                (
                    [id] => 3
                    [level] => CFO
                )
        )
)</code>

如何递归成如下格式呢?多谢各位。

<code>Array
(
    [0] => Array
        (
            [id] => 1
            [level] => CEO
        )
    [1] => Array
        (
            [id] => 2
            [level] => CTO
        )
    [2] => Array
        (
            [id] => 3
            [level] => CFO
        )
)
</code>
