Search http://php.net for "variable variables" (Yes, really.)

It will let you turn 'qty' . $i into a new variable and get its value.

You probably should be using an ARRAY for qty anyway, though...

<input name="qty[product_id_47]">
<input name="qty[product_id_83]">
<input name="qty[product_id_99]">

Then you can use $_POST['qty'] as an array, and not mess around with
variable variables.
