Operating mode
Here we try to give you a little introduction of how the script works:
Every site you want to track has to have the same single line of javascript included. If you now visit such a site, your browser will include the external javascript that is referenced in the loaded website. This javascript calls a php script that tracks all visitors data in a textbased logfile and places a 1-pixel image in the called site. Now you can run the statistic script to see all user activities. By every call of this script, all values of the logfile will be read.
