Build decision tree, train the tree and classify new data. Supports multiple discrete value for each attributes, eg: attribute[wind] can have three values (strong, mild, weak).

Decision Tree Learning for PHP (ID3 Algorithm)

Decision tree learning is one of the most widely used and practical methods for inductive inference. It is a method for approximating discrete-valued functions that is robust to noisy data and capable of learning disjunctive expression. -- Machine Learning by Tom M.Mitchell

This library is intended for experimental usage. I'm newbie in machine learning. I tried to incorporate my undertanding on decision tree learning algorithm into php, but it's experimental. Code is unproductive and error prone.
