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))) ;

    }

?>
