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.
