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);
?>
