Yes. In the example that your form was posted, and you have track_vars = on in your php.ini, all of the form elements will be held in the array $HTTP_POST_VARS (same holds true for $HTTP_GET_VARS).
Now you can loop through like this:
while(list($key, $value) = each($HTTP_POST_VARS)) {
// Now $key is the form element and the value is in $value
}
Hope that helps..
