Assuming your form is method="POST" then we can simply do:
<?php
  print_r($HTTP_POST_VARS);
?>
It'll show exactly what names/values have been posted.  If you're unsure
of the form method, $_REQUEST will work too (introducted PHP 4.1.0), so:
  print_r($_REQUEST);
If you simple want to cycle through the variables, consider a while loop
or a foreach statement:
if (count($HTTP_POST_VARS) > 0) {
  foreach ($HTTP_POST_VARS as $key => $value) {
    print "$key => $value <br />\n";
  }
}
