You can create form fields with array notation, for example:

<inputtype="text" name="quantity[productid]">

<inputtype="text" name="quantity[3]">
<inputtype="text" name="quantity[4]">
<inputtype="text" name="quantity[2]">

foreach ($_POST['quantity'] as$productId => $quantity) {
    echo (int) $productId . ':' . (int) $quantity;
    //etc.
}
