Artificial Neural Networks on a Tic Tac Toe console application

Artificial Neural Networks are used in a wide variety of fields as ways for machines to "learn" based on information, by modeling how the brain works.
We will explore ANN theory and see how we can use them in PHP through code snipets of a a toy Tic Tac Toe game console application and in the way, learn a bit about Symfony's greate Console component. With live demos!
