The Judy class
(PECL judy >= 0.1.1)
简介
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);
?>
