How can a PHP loop be used to automatically adjust entry numbers in a guestbook after deletions?

When a guestbook entry is deleted, the entry numbers of subsequent entries need to be adjusted to maintain a sequential order. This can be achieved by using a PHP loop to iterate through the remaining entries and update their entry numbers accordingly. 

// Assuming $guestbookEntries is an array containing guestbook entries
// and $deletedEntryNumber is the entry number of the deleted entry

// Adjust entry numbers after deletion
foreach ($guestbookEntries as $key => $entry) {
    if ($entry['entry_number'] > $deletedEntryNumber) {
        $guestbookEntries[$key]['entry_number'] -= 1;
    }
}

// Update the guestbook entries in the database or wherever they are stored
