Convert an adjacency list to a nested set adjacency list combo.

TreeTransform

Here is the TreeTransform package. Really it's just a class and a quick example. Ported from the answer to this StackOverflow question: http://goo.gl/J60wf Here are my ridiculous assumptions:

1. RedBeanPHP is configured to use the R facade.
2. The targeted TABLE contains a properly formed adjacency list with `parent` being the column name of the self-join foreign key.
3. TABLE contains two, otherwise unused, integer columns named `lft` * and `rht` (e.g., table contains contains, at least, these fields:

   
    CREATE TABLE IF NOT EXISTS `adjacency_nested_combo` (
            `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
            `parent` int(11) unsigned DEFAULT NULL,
            `lft` int(10) unsigned NOT NULL,
            `rht` int(10) unsigned NOT NULL,
        PRIMARY KEY (`id`)
        ) ENGINE=InnoDB  DEFAULT CHARSET=utf8;
    

   </li>
   

If you want to try it out just do the following:

1. Create a database and fill with the example data.
2. Configure ./config/config.php (you need your password and databasename).

Hope this turns out to be useful.
