PHP match data into array

Question

I'm not sure if there is some kind of php function that will help me do this fairly simply or not. I figured I'd ask.

Let's say I have 5 products [prod1, prod2, prod3, prod4, prod5]

All of these products are related to eachother, so I need to arrive at something like this:

prod1, prod2, prod3, prod4, prod5

prod2, prod3, prod4, prod5, prod1

prod3, prod4, prod5, prod1, prod2

prod4, prod5, prod1, prod2, prod3

prod5, prod1, prod2, prod3, prod4

echo, save as variables, it doesn't matter to me.

In my example I said 5, but in reality there could be any number of products. Is there a function that does this automatically up to n products?? I don't even know what to really call this other then I'm matching them together.

Answer 1

You can do this:

$arr = array($prod1, $prod2, $prod3, $prod4, $prod5);

for ($i = 0; $i < count($arr); $i++) {
    array_push($arr, array_shift($arr));
    print_r($arr);
}
