Are there specific PHP functions or methods that can help simplify the process of submitting and displaying guestbook entries without additional pages?

To simplify the process of submitting and displaying guestbook entries without additional pages, you can use AJAX to submit the form data asynchronously and update the guestbook entries dynamically without requiring a page refresh. 

<?php
// PHP code to handle form submission and display guestbook entries

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data and save to database

    // Return success message or error message
    echo json_encode(array("success" => true, "message" => "Entry submitted successfully"));
    exit;
}

// Display guestbook entries
// Fetch entries from database and display them
