如何解决将数字键替换为默认的0-1-2等多维数组中的键
[stringKey] =>数组 （ [ 13 ] =>数组 （ [id] => 13 [名称] => smth [some_array] =>数组 （ [ 28 ] =>数组 （ [s_a_id] => 28 [名称] => smth [分支] =>数组 （ [0] =>数组 （ [b_id] => 1 [名称] => s_b_name_0 ）
[1] => Array
(
[bid] => 87
[name] => s_b_name_1
)
[**29**] => Array
(
[s_a_id] => **29**
[name] => smth1
[branches] => Array
(
[0] => Array
(
[b_id] => 8
[name] => s_b_name_2
)
)
)
)
[**12**] => Array
(
[id] => **12**
[name] => someName
[some_array] => Array
(
[**12**] => Array
(
[s_a_id] => **12**
[name] => someString
[branches] => Array
(
[0] => Array
(
[b_id] => 3
[name] => another_name
)
[1] => Array
(
[b_id] => 4
[name] => another_value_name
)
)
)
)
)
)
我需要将数字数字键替换为默认的有序键，例如0-1-2等：
[stringKey] =>数组 （ [ 0 ] =>数组 （ [id] => 13 [名称] => smth [some_array] =>数组 （ [ 0 ] =>数组 （ [s_a_id] => 28 [名称] => smth [分支] =>数组 （ [0] =>数组 （ [b_id] => 1 [名称] => s_b_name_0 ）
[1] => Array
(
[bid] => 87
[name] => s_b_name_1
)
[**1**] => Array
(
[s_a_id] => **29**
[name] => smth1
[branches] => Array
(
[0] => Array
(
[b_id] => 8
[name] => s_b_name_2
)
)
)
)
[**1**] => Array
(
[id] => **12**
[name] => someName
[some_array] => Array
(
[**0**] => Array
(
[s_a_id] => **12**
[name] => someString
[branches] => Array
(
[0] => Array
(
[b_id] => 3
[name] => another_name
)
[1] => Array
(
[b_id] => 4
[name] => another_value_name
)
)
)
)
)
)
漂亮的格式：
