新人求教数组问题

$goods_spec_cond = array(
1=>array(
“2”=> “蓝色”,
“3”=> “红色”,
“21”=> “颜色随机”,
“23”=> “黑色”,
“27”=> “灰色”,
“31”=> “白色”
),
2=>array(
“4”=> “s”,
“5”=> “m”,
“6”=> “l”,
“28”=> “均码”,
“32”=> “xl”,
“33”=> “xxl”
)
) 这样的一个数组 如何遍历 让一个颜色对应下面多个全部尺码,最终结果应该是下面这样
array(
“i_24″=>array(
“2”=> “蓝色”,
“4”=> “s”
),
“i_25″=>array(
“2”=> “蓝色”,
“5”=> “m”
),
“i_26″=>array(
“2”=> “蓝色”,
“6”=> “l”
),
“i_228″=>array(
“2”=> “蓝色”,
“28”=> “均码”,
),
“i_232″=>array(
“2”=> “蓝色”,
“32”=> “xl”,
),
“i_233″=>array(
“2”=> “蓝色”,
“33”=> “xxl”,
),
“i_34″=>array(
“3”=> “红色”,
“4”=> “s”,
),
)数组没写完,但是格式是这个样子的 i_24 是 键名和键值组合起来的,请各位大神帮帮忙,方便的话给思路最好
