How can one display the IP of a user after they have posted in a guestbook using PHP?

To display the IP of a user after they have posted in a guestbook using PHP, you can use the $_SERVER['REMOTE_ADDR'] variable to retrieve the user's IP address. You can then store this IP address in your database or display it on the guestbook page.

// Get the user's IP address
$user_ip = $_SERVER['REMOTE_ADDR'];

// Display the user's IP address
echo "Your IP address is: " . $user_ip;
?>
