近期在开发一个电商系统，做到了商品模块。虽然增删改查在所难免，但是商品这块更多的是js的调用等效果。还有更为重要的就是商品sku的批量生成与组合了。
不同的系统有不同的需求，以下的需求就是要添加完各种规格后批量生成sku的。【推荐学习：PHP视频教程】

页面代码这里就不说了，sku的生成方式是根据所有规格进行组合，也就是数学上的笛卡尔积，我用php写了两种方式，记录一下。
第一种，生成字符串
实际开发中，你只要生成上面的二维数组就可以组合了，效果如下：
Array
(
[0] => 白色-64G-移动-国行
[1] => 白色-64G-移动-港版
[2] => 白色-64G-电信-国行
[3] => 白色-64G-电信-港版
[4] => 白色-64G-联通-国行
[5] => 白色-64G-联通-港版
[6] => 白色-128G-移动-国行

[10] => 白色-128G-联通-国行
[11] => 白色-128G-联通-港版
[12] => 银色-64G-移动-国行
[13] => 银色-64G-移动-港版

[23] => 银色-128G-联通-港版
[24] => 玫瑰金-64G-移动-国行
[25] => 玫瑰金-64G-移动-港版

[32] => 玫瑰金-128G-电信-国行
[33] => 玫瑰金-128G-电信-港版
[34] => 玫瑰金-128G-联通-国行
[35] => 玫瑰金-128G-联通-港版
)第二种，生成数组格式
输出打印结果
