The other suggestion is a good one but if you want to do it with the
variables as you named them you can also use something like this:

for ($i = 0; $i < $maxlines; $i++) {
$tax = $_POST['tax' . $i];
$amount = $_POST['amount' . $i];
$type = $_POST['type' . $i];
.....
}

There is more one should usually do here, for security -- anything
coming in via _POST should be processed through functions designed to
remove malicious data. For example, an approach something like this:

$value = strip_tags((substr(trim($_POST[$fldname]), 0, MAX_LEN));
