The Judy class

INTRODUCTION

	The  Judy  class  implements  the  ArrayAccess interface and the Iterator interface. This class, once instantiated, can be accessed like a
       PHParray.

	A PHP Judy object (or Judy Array) can be one of the following type :

	      oJudy::BITSET

	      oJudy::INT_TO_INT

	      oJudy::INT_TO_MIXED

	      oJudy::STRING_TO_INT

	      oJudy::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);
	      ?>
