	1. Property sheets drawing engine		nested sets

Supplied by: Alexander Selifonov <e-mail contact>

Create Web based configuration wizards

This package can be used to create Web based user interfaces for configuring sets of properties.

It can compose and generate HTML forms with fields that appear split between multiple pages. The form pages may be browsed using a tab or wizard like user interface.

The form may be composed adding several types of fields to each form page.

	2. Nested Sets DB Tree		nested sets

Supplied by: Kuzma Feskov <e-mail contact>

Manipulate database records in hierarchical trees

This class can be used to manipulate nested sets of database table records that form an hierarchical tree.

It provides means to initialize the record tree, insert record nodes in specific tree positions, retrieve node and parent records, change position of nodes and delete record nodes.

It uses ANSI SQL statements and ADODB library to make it work with many database types.

It uses caching of SQL queries to minimize database access overhead.

Support of transactions on the basis of class ADODB.

The library works with support multilanguage interface of technology GetText (autodetect).

	3. Eval Math		nested sets

Supplied by: Miles Kaufmann <e-mail contact>

Safely evaluate mathematical expressions

This class can be used to safely evaluate mathematical expressions.

The class can take an expression in a text string and evaluate it by replacing values of variables and calculating the results of mathematical functions and operations.

It supports implicit multiplication, multivariable functions and nested functions.

It can be used to evaluate expressions from untrusted sources. It provides robust error checking and only evaluates a limited set of functions.

It could be used to generate graphs from expressions of formulae.

	4. MyTemplate		nested sets

Supplied by: Dmitry Levashov <e-mail contact>

Powerfull template engine

MyTemplate is very powerful template engine. It allows including a nested template file directly into another template file and automaticaly parse it in any template in set.

Working with dinamic blocks is so easy. Only assign block variables and get result. You do not need to parse each block 'manualy'.

Automaticaly parses PHP constant and global variables into templates.

Supports multiply template directories.

You'll like it :) Your code will become shorter :)

	5. Joe Celko Nested Sets		nested sets

Supplied by: Setec Astronomy <e-mail contact>

Manage tree database structure with Celko approach

This class is meant to manage tree database structure using Jeo Celko's nested sets approach.

You can add node with 7 queries, delete a node with subnodes with 4 queries and move node with 11 queries.

The number of queries per action does not depend on the number of sub-nodes, so it is a scalable solution.
