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 );
 ?>
