The composition permutation algorithm of PHP array content without repetition

Recently in the Ecshop Inventory module, we set up inventory of multiple attribute combinations for a product, such as:

A phone with different colors, screen size, system and power, to set up a different inventory, if you have to manually select the attribute combination, it will take a lot of unnecessary time. If you have set the property arrangement combination when you open the page, then it would be best to think about it all day and write the following function:
