How to find every possible combination of an arbitrary number of arrays in PHP
- by Travis
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,
