Hello guys!
Assume an arbitrary number of arrays, like so:
$color = array("blue", "green", "yellow");
$size = array("small", "large");
$weight = array("light", "medium", "heavy");
What I want to do is find all the possible unique element combinations between the elements of these arrays. Think of a car that is blue, small and light, or blue, small and heavy. This is what works for three arrays:
function arrays_mix(){
$args = func_get_args();
foreach($args[0] as $value[0]){
foreach($args[1] as $value[1]){
foreach($args[2] as $value[2]){
$combinations[] = implode(", ",$value);
}
}
}
return $combinations;
}
/*
Output:
Array
(
[0] => blue, small, light
[1] => blue, small, medium
[2] => blue, small, heavy
...
[17] => yellow, large, heavy
)
*/
Obviously, I want to accept an arbitrary number of arguments. I am certain that recursion is the answer and I’ve tried a lot of things that just don’t work. Can you guys help me out? I am definitely stuck right now.
