PHP Multi Dimensional Array Combinations

This PHP function will take a multi dimensional array and create all its possible combinations (not permutations). I used this function in debug code, but I can see its use in many other cases.

I used this function in debug code, to test possible uses of an unknown API quickly, but I can see the use of this function in other cases, such as:

Debug code, unit testing
A/B/n split testing engines
Text spinning engines

Have a look at the output to see if this is indeed what you are looking for.

Thanks for this, I spent yonks tearing what’s left of my hair out trying to do the same thing with indexes and failing – before I cheated and googled and eventually found your very nice solution.

Used it to generate initial stock data for products with multiple options.

Thanks a lot, this was very helpful for me.
my case is the A/B/n split testing (specifically MVT).
Regards.

Man, you totally saved my sanity. This function is so terribly useful. Looks like a simple problem, yet I’ve been banging my head into a brick wall of code-blindness for hours now.
