How to erase messages from PHP scripted Guestbook

Good day to all
I have just finished installing a guestbook from flash-db.com and its working fine

only problem is, i need to learn how to erase entries and im still not sure what to do

  1. i realise i have to make a new Flash movie with delete capabilities. this much i think i can handle.
  2. the tricky end is writing the PHP. i found the PHP script below , and am thinking of using it. I am a little nervous though, as it took me ages to get the original script working…i have pasted it below so if anyone wants to they can check it out. im not even sure if i should use this script to completely replace the original …

any tips or trickcs much much appreciated thankyou very much

Some of you might be interested in this. I modified the Guestbook v2 script so that you can use an administration tool to edit or delete the entries. Here’s the code for the Guestbook.php file:
