For each visitor, BBClone counter can display: IP address with reverse DNS, operating system, browser, country, search engine keywords, referring URL (where do they come from), visit date, page visits and number of visitors in a graphical interface. No database is required, just add a few lines into the PHP pages to be tracked and the code does not appear in the source. Tar ball and Zip downloads available onsite and live demo here: http://bbclone.de/demo/.
