Judy (class)

The Judy class

Introduction

(PECL judy >= 0.1.1)

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

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 ?>
