$_POST['howmuch' . $s];
seems to be what you mean.

You can, if it helps, get PHP to make $_POST['howmuch'] be a proper
array rather than having five separate numbered elements in $_POST. You
do this by writing array brackets in the input element's name:
name="howmuch[<?php echo $s ?>]"
Upon submission, $_POST['howmuch'] will then be an array you can index
like this: $_POST['howmuch'][0] and so on. Thus you'd write
value="<?php echo $_POST['howmuch'][$s] ?>"
if you needed to show the value entered.
