New from the PHPMath website this morning, there's an update from the author of the Web site user modeling with PHP article from IBM's website, creating the PHPMath_Webstats package.

I have just finished uploading some new and improved versions of the code discussed in my IBM developWork's tutorial Web site user modeling with PHP. I combined the header.php and footer.php files into a class called VisitorLog.php. This required making much of the logging code more object oriented. The main impetus for this work was to make it easier to embed the logging code into arbitrary Web sites. I also took this opportunity to add a few more variables to keep updated tallies on - the state frequency matrix and the number of states to date. These tallies are anticipated to be useful for other transitional modelling computations we might want to perform.

He continues on to talk about some of the other reasons for updating the code, including: Provide a PHP-based workbench for studying issues related to Web site user modelling and Initiate development of a suite of PHPMath_Webstats classes for advanced analysis of clickstream data. The reason for this move to an official package is to have a nice, release-based development process and to apply AI principles as best possible to the gathering of web statistics.
