Creating A Guestbook Using PHP?
I am having trouble creating a guestbook using php? I used functions but when I upload it to the server that I am using it is saying that my closing </html> tag is missing something. I have no idea what it is either. I was wondering if someone could help me out and take a look at my code.
<?php echo "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?".">"; ?>
