Answer 1

You can have the foreach loop show the index along with the value:

foreach ($_POST as $key => $entry)
{
     print $key . ": " . $entry . "
";
}

As to the array checking, use the is_array() function:

foreach ($_POST as $key => $entry)
{
     if (is_array($entry)) {
        foreach($entry as $value) {
           print $key . ": " . $value . "
";
        }
     } else {
        print $key . ": " . $entry . "
";
     }
}
