How can PHP be used to dynamically display user-specific information, such as usernames, in comments within a guestbook script?

To dynamically display user-specific information such as usernames in comments within a guestbook script, you can use PHP to retrieve the user's information from a database or session variable and then insert it into the comment template before displaying it on the page. 

// Assuming the user's information is stored in a session variable
$userName = $_SESSION['username'];

// Fetch comments from database and loop through each comment
foreach ($comments as $comment) {
    echo "<div class='comment'>";
    echo "<p><strong>$userName</strong>: $comment</p>";
    echo "</div>";
}
