I have an arbitrary number of nested arrays in php. For example:

Array
(
    [0] => Array
        (
            [0] => 36
            [0] => 2
            [0] => 9
        )

    [1] => Array
        (
            [0] => 95
            [1] => 21
            [2] => 102
            [3] => 38
        )

    [2] => Array
        (
            [0] => 3
            [1] => 5
        )

)

I want to find the most efficient way to combine all possible combinations of each of these nested arrays. I'd like to end up with something that looks like this...

Array
(
    [0] => "36,95,3"
    [1] => "36,95,5"
    [2] => "36,21,3"
    [3] => "36,21,5"

    etc...

)

The order the results are combined in is not important. That is to say, there is no difference between "3,95,36", "36,95,3", and "95,36,3". I would like to omit these redundant combinations.

Any suggestions on how to go about this would be much appreciated.

Thanks in advance,
