Assoc Array name printing

[ChaosXero]

I have an array I'm using for errors and I'd like it to output the name of the array section i.e.

array error() =
    username = 1

I want to output

Bad 'Username!' (told to do so because username = 1)

I just need to know what to do to output the 'name' of an item in an array.  Hope this makes sense.

Does this help?

[code=php:0]
foreach ($error as $k => $v) {
  if ($k == 'username' && $v == 1) {
    echo "Bad $k!";
  }
}
[/code]
