phpOpenTracker is a framework solution for the analysis of Web site traffic and visitor behaviour. It features a logging engine that, either invoked as a Web bug by an HTML image tag or embedded with two lines of code into your PHP application, logs each request to a Web site into a database. One installation can track an arbitrary number of Web sites. Through its API, you can easily access the gathered data and perform complex operations on it (for instance, the analysis of your visitors' click paths).
tClick is a set of PHP scripts designed to provide tracking of click-throughs of links on a Web site for those who don't have access to their site logs or don't want to bother with complex log analysis programs. The system's backend is provided by a MySQL database, and support is included for addition, deletion, and viewing of link statistics through a Web interface as both individual links and by categories.
Web Log Trends Analyzer provides a work-around for a "bug" in some popular commercial Log Analyzer products, which makes them unable to process multiple log files for overlapping periods of time. If you like your commercial Log Analyzer, and don't feel like upgrading just yet, this little Perl script will do the trick nicely. Simply specify a list of all your log files, and it will consolidate them into a single log file, sorted by time. The output log will work with your commercial Log Analyzer product without a hitch, allowing you to continue using it to generate reports.
Unique Visitor Counter is a very simple script that records visits from unique IP-addresses to a Web site. Unlike an ordinary hit counter, it will not increment at refresh. It also comes with a user- friendly setup script, eliminating the need for extensive PHP knowledge to use it.
