PHP script that counts visits on webpages and displays statistics as HTML/CSS
if a logfile analyzer solution is not suiteful. All data is stored in textfiles so no
MySQL database is needed. IP adresses of visitors are stored a specific time to
prevent multiple counting.
back to top
Include the PHP Code into a PHP file or insert it in any HTML code and rename
the file from <name>.html to <name>.php
Edit the 'preferences' section at the top of the file:
The path's of the two data files must be writable; the files will be generated
automatically. Set 'start_time' to the date that should be displayed in the output.
Set 'startnum' to an initial value if the counter should not start with zero. Now
you can use both the variables $y (the counter) and $start_time at any point in the file.
Simply write into the HTML code: <?php print $y; ?> and <?php print $start_time; ?>.

Every time the file with the script is viewed, the counter checks if the IP adress
of the visitor is stored. If yes, it decides upon the setting 'maxip_time' if the
counter gets incremented or not. IP adresses older than 'maxip_time' are deleted
regularly. With the setting 'max_ip' the maximum number of stored IP adresses is
specified. Both the settings can be altered arbitrarily after the first run.
