NaiveBayesClassier for php

I want to implement a NaiveBayesClassifier in my project found on this link> https://github.com/tistaharahap/Simple-Naive-Bayes-Classifier-for-PHP
I have created a database in Mysql to store word documents and l want to classify those documents using naive classifier. If i run the index.php file in my commandline l am getting the following output
> Classifier started.
>array(0){}
>Memory Usage:256KB
>Time spent…seconds

The classifier is supposed to classify the documents but this is the only output what might be the cause?

Archive post, looks like it was a mistake since the second had the added link. No further action needed here.
