# The Judy class

(PECL judy >= 0.1.1)

## Introdução

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 :

- Judy::BITSET
- Judy::INT_TO_INT
- Judy::INT_TO_MIXED
- Judy::STRING_TO_INT
- Judy::STRING_TO_MIXED

Exemplo #1 Judy array example

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