The Judy class

(PECL judy >= 0.1.1)

Introduction

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 :

Example #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);
?>
