+The PHPMonitor is a small PHP script with has to be pre-prended to all other PHP scripts of a website. This can be done either manually (unreliable) or by configuring the php.ini file of a server appropriatly (not always possible). The script relies on a cookie for the user identification to be available thorugh the [http://httpd.apache.org/docs/2.2/mod/mod_usertrack.html Apache module mod_usertrack].
