How can PHP be utilized to sort and display guestbook entries in reverse chronological order?

To sort and display guestbook entries in reverse chronological order using PHP, you can retrieve the entries from a database in descending order based on the timestamp of each entry. Then, you can loop through the sorted entries and display them on the webpage. 

<?php
// Assuming $entries is an array of guestbook entries with 'timestamp' as one of the keys
usort($entries, function($a, $b) {
    return strtotime($b['timestamp']) - strtotime($a['timestamp']);
});

foreach ($entries as $entry) {
    echo $entry['name'] . ': ' . $entry['message'] . '<br>';
}
?>
