How can prototyping in Frontpage help in developing a PHP guestbook?

Prototyping in Frontpage can help in developing a PHP guestbook by allowing you to design the layout and functionality of the guestbook interface before writing the actual PHP code. This can help you visualize the user experience and make any necessary adjustments before diving into the coding process.

<?php
// PHP code for handling form submission in a guestbook

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST["name"];
    $message = $_POST["message"];
    
    // Save the guestbook entry to a file or database
    $entry = $name . ": " . $message . "\n";
    file_put_contents("guestbook.txt", $entry, FILE_APPEND);
    
    // Redirect back to the guestbook page after submitting the entry
    header("Location: guestbook.php");
    exit();
}
?>
