Variables external to a function are only valid if:

1) They are superglobals (i.e. $_SESSION, $_GET, $_POST, etc.),
2) They are defined as global in the function, or
3) They are passed to the function.

#3 is the best way to go for user variables; just pass the $username as
a parameter to the function.
