(PECL judy >= 0.1.1)
はじめに
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 :

<?php $judy = new Judy(Judy::INT_TO_MIXED); $judy[1] = "one"; $judy[2] = array('a', 'b', 'c'); $judy[3] = new Judy(Judy::BITSET);?>
