Garry,
Sjoerd is correct - you really want to use arrays. They're much easier than
your route, and the code much cleaner.
And you might as well get your feet wet with arrays now - they are very heavily
used in PHP. This is a great way of doing it.
Simply name your fields in the html something like:
<input name="personage[]" ...>
Then in your code (no error checking included):
$personage = $_POST['personage'];
// $personage now contains the entire list of names
foreach ($personage as $person) {
// $person contains the first name in the first loop iteration,
// the second name in the second iteration, etc.
doSomethingToPerson($person)
}
