php求助如何将二维数组变成一维数组？

Question

现在有一个二维数组格式如下： Array ( [0] => Array ( [id] => 38 [goods_id] => 77426 [model_name] => 颜色 [model_sub_name] => Array ( [0] => 黑色 [1] => 白色 [2] => 红色 [3] => 浅蓝色 [4] => 紫色 ) [goods_stock] => Array ( [0] => 321 ) [curr_price] => Array ( [0] => 99 ) [goods_weight] => Array ( [0] => 280 ) ) [1] => Array ( [id] => 39 [goods_id] => 77426 [model_name] => 尺码 [model_sub_name] => Array ( [0] => 32A [1] => 34A [2] => 36A [3] => 32B [4] => 34B [5] => 36B [6] => 38B [7] => 34C [8] => 36C [9] => 38C [10] => 40C [11] => ) [goods_stock] => Array ( [0] => 321 ) [curr_price] => Array ( [0] => 99 ) [goods_weight] => Array ( [0] => 280 ) ) ) 现在需要将这个二维数组变成如下格式： Array ( [0] => Array ( [model_name] => 颜色 [model_sub_name] => 黑色 [goods_stock] => 321 [curr_price] => 99 [goods_weight] => 280 ) [1] => Array ( [model_name] => 颜色 [model_sub_name] => 白色 [goods_stock] => 321 [curr_price] => 99 [goods_weight] => 280 ) ……这里省略N个数组 [N+1] => Array ( [model_name] => 尺码 [model_sub_name] => 32A [goods_stock] => 321 [curr_price] => 99 [goods_weight] => 280 ) [N+2] => Array ( [model_name] => 尺码 [model_sub_name] => 34A [goods_stock] => 321 [curr_price] => 99 [goods_weight] => 280 ) 这里也省略总数组第二个元素的几条记录 ) 在上述数组中goods_stock、curr_price、goods_weight都是数组，如果这几个键中的数组只有一个元素，那么在model_name一样的前提下，goods_stock、curr_price、goods_weight都取这一个值，否则，就取model_sub_name中元素下标对应的goods_stock、curr_price、goods_weight中的值。比如model_sub_name为“白色”时对应的下标是1，上述数组中goods_stock、curr_price、goods_weight都只有一个元素，那么就取这一个元素的值，如果不是一个元素，则取goods_stock[1]、curr_price[1]、goods_weight[1]的值，不知道这样的描述是否理解。求助大神帮忙解决一下。

Answer 1

需要先设置一个空数组，然后两层循环，第一层循环大数组，第二层循环里面的model_sub_name，然后给空数组赋值就行了
