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);
