A simple, small but inefficient, guestbook written in pure PHP (while on PCP).
files
index.php - the index page (from where you post/see other posts)
result.php - posts the post
comments.json - the comments file, stored in pure json
are expected to be in your webroot
files
bans.json - banned ip list
log.json - one log file on who did what
are expected to not be in your webroot, it defaults to /home/www-data by default
change the directories in which the files above should be stored at, set the appropriate permissions for the folders where PHP is going to write files to and you're set
