Note Submitter: andreas dot sandin at brun7 dot tk ---- Hi! Would consider myself a beginner at PHP. Am writing a very simple guestbook. Messages are simply stored in .txt-file which the guestbook script reads through when entering the site. My problem is how to be able to append messages in the beginning of the file without overwriting existing messages. Now, the latest added message is added at the end of the file and therefor also at the bottom of the guestbook. Have tried with the different parameters w, a, and r+ when the script opens the file. Is this solvable or should I start to think about using a database? Thankful for any help at all.
