Simple PHP Tree - Nested sets for PHP and MySQL

This a simple PHP tree class for managing multi-root nested set tables. You can create new nodes in the tree, move them left, right, up and down. You can also delete nodes and preserve its children or you can delete complete subtrees.

There is a build in function that shows the health status of the tree table. If the tree gets broken for some reason you can simply reset the tree by calling the resetNodes() method.

Take a look at the index.php file for a full feature example. There you will also find a example function that renders a simple multi-level ul-list.

Table structure for testing

For testing purposes you can use the following table structure:

CREATE TABLE IF NOT EXISTS `tree_001` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `left` int(11) NOT NULL,
  `right` int(11) NOT NULL,
  `level` int(11) NOT NULL,
  `move` int(11) NOT NULL,
  `data_column_1` text NOT NULL,
  `data_column_2` text NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
