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.
