我已经查找了很多与此类似的线程，但主要的区别在于，在那些线程中，＆＃34;孩子＆＃34;元素每个只有1个值。我的问题略有不同：
你有一个2级数组，其中第一级是＆＃34;选项类型＆＃34; （即：颜色，尺寸，面料等），第二级是＆＃34;选项值＆＃34; （即：红色，蓝色，6号，7号，皮革，棉等）。我希望＆＃34; flatten＆＃34;这个阵列组合成一个单一级别的数组，结合了选项（即：红色 - 大小6 - 皮革，红色 - 大小6 - 棉，蓝色 - 大小6 - 皮革等）。
因此，如果有2个选项类型，每个类型有7个选项，则生成的数组将有49个键，如果有3个选项类型，每个类型有5个选项，则生成的数组将有125个键。
示例数据集（2种选项类型，每种选项有2个选项）
