submit button arrays in PHP

submit button arrays in PHP

<div id='Descp'><?php echo $rows['productName'];?></div><!--decpx-->
<div id='buynow'><input type='submit' name='buyNow[]' id='buyNow'
class='buynow' value='Buy' /></div>
My question is, is it possible to create arrays of submit buttons like
above? Simply the need is to assign a submit button to capture the product
type user picks and then redirect to another page to buy.
Second point is using foreach will be a good method to capture the clicked
button response?
Thanks
