The Judy class
(Информация о версии неизвестна, возможно, только в SVN)
Введение
The Judy class implements the ArrayAccess interface and the Iterator interface. This class, once instantiated, can be accessed like a PHP array.
A PHP Judy object (or Judy Array) can be one of the following type :
Пример #1 Judy array example
$judy = new Judy(Judy::INT_TO_MIXED);
$judy[1] = "one";
$judy[2] = array('a', 'b', 'c');
$judy[3] = new Judy(Judy::BITSET);
