How can PHP be used to limit the number of entries displayed on a page, such as in a guestbook?

To limit the number of entries displayed on a page, such as in a guestbook, you can use PHP to control the number of entries fetched from the database and displayed on the page. This can be achieved by using a combination of SQL queries and PHP logic to retrieve only a specific number of entries at a time. 

// Set the limit of entries to display per page
$limit = 10;

// Calculate the offset based on the current page number
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($page - 1) * $limit;

// Fetch entries from the database with the limit and offset
$query = "SELECT * FROM guestbook_entries LIMIT $limit OFFSET $offset";
$result = mysqli_query($connection, $query);

// Display the entries on the page
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['entry_content'] . "<br>";
}

// Add pagination links for navigating between pages
$total_entries = mysqli_num_rows(mysqli_query($connection, "SELECT * FROM guestbook_entries"));
$total_pages = ceil($total_entries / $limit);

for ($i = 1; $i <= $total_pages; $i++) {
    echo "<a href='guestbook.php?page=$i'>$i</a> ";
}
