Code for:

you will be creating a simple guestbook on your website. The guestbook will allow users to add an entry to the guestbook. Entries to the guest book must include a Subject , Time and Date of the posting (which is obtained by php), Name and Email of the person who is making the post , and his/her Comments. When the php page is loaded, the user should view the guestbook entries. You should just use a text file for storing the guestbook entries in between requests. Note: your php file also needs to validate the form data and make sure the fields are not empty.
