Iterating through a Judy array with key as string and values of any type:

<?php
    $judy = new Judy(Judy::STRING_TO_MIXED);
    $judy["foo"]     = "bar";
    $judy["veggie"]  = "carrot";
    $judy["taste"]   = "sweet";

    if($judy->count() > 0) {
        $key = $judy->first();
    do {
        var_dump($judy[$key]);
    }while (!is_null($key = $judy->next($key))) ;
    }
?>
