The content of a two-dimensional array are arranged in combination

 

Recently doing ecshop commodity inventory module, respectively, to the plurality of combinations of attributes of a product inventory is provided, as shown below:

 

 A cell phone has a different color, screen size, and power systems, should set a different stock, if have to manually select the combination of attributes, will be a lot of unnecessary time-consuming. If you already set when you open the page properties of permutations and combinations would be best, however, and therefore want the whole day, I wrote the following function:

If the source coordinates need to combine content using the following method
