This line gave me an error when I tried it. I don't knwo exactly what you 
meant to write here, but what you wrote isn't valid php.

Loop through the post data using something like (untested):

$vals = array();
foreach ( $_POST as $field => $data ) {
if ( preg_match( "howmuch(\d+)", $field, $bits ) === 1 )
$index = intval( $bits[1] );
$vals[$index] = $data;
}

$vals[X] now contains the data that was in the field $_POST["howmuchX"] 
where X is a sequence of 1 or more digits.
