Of course, a database-based guestbook can be made very beautiful, and it is also easier to manage. But for those friends who don't have database space, the text-based guestbook can also be used on personal sites. And as long as we work hard, we can do a good job, and it can even be said to be no worse than a database-based guestbook. Here I introduce a text-based guestbook. You can see its demonstration at the following address: http://bamboo.oso.com.cn/note.htm. It has the following two characteristics:
1. Use different colors to display comments posted by different people;
2. Each commenter has the ability to select a small icon.
This guestbook is composed of the following four files: the note.txt file that records the content of the message; the color.txt file that records the color of the message text; both of these files can be created with notepad. The note.htm file that reflects the message form; the note.php file that ultimately processes the message information.The following is their source code:
note.htm:

              $f = fopen("color.txt","r+");
