$final = array();
$Y = explode(',', $y);
foreach(explode(',', $x) as $key => $val ) {
$final[$val] = $Y[$key];
}
var_dump($final);

What is the relationship between the $x,$y and $product,$price?
I'm not sure I quite grasp what your trying to do.
If I understand correctly, the situation you describe ends up not
being a one-one relationship. So a user could select 4 prices with
3 products or vice versa. Which will make things difficult to match
up products/prices.
