Zebra_Mppt 2.2.3

This is a php algorithm script providing an implementation of the modified preorder tree traversal algorithm. MPTT is a fast algorithm for storing hierarchical data in a relational database.

Zebra_Mppt script integrates this complicated algorithm with PHP applications, providing tools for adding, deleting, moving and copying nodes around the tree. It can also be used to query the nodes for information.

To avoid database corruption, Zebra_Mppt always uses table locks. Integrated with Zebra_Mppt  is a caching algorithm, so a node is read only once per script execution.

Requirements:
- PHP 4.4.9 or Higher
- MySQL 4.1.22 or Higher

What's News in This Version:
- Fixed a bug that escaped fixing in the previous release, where the get_selectables() method was triggering a “Strict Standards” notice in PHP 5.3+.
- Fixed a bug where the “copy” method was not working correctly.
