Is that possible? $final = array(); $Y = explode(',', $y); foreach(explode(',', $x) as $key => $val ) { $final[$val] = $Y[$key]; } var_dump($final); > > I have a form, with checkboxes that are named $product[1] through [40].

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. Curt -- The above comments may offend you. flame at will.
