How can PHP developers optimize their code to handle pagination in scenarios like displaying guestbook entries on multiple pages?

To optimize code for handling pagination in scenarios like displaying guestbook entries on multiple pages, PHP developers can use SQL queries with LIMIT and OFFSET clauses to fetch a specific number of entries for each page. By dynamically calculating the total number of pages based on the total number of entries and the desired number of entries per page, developers can efficiently display entries across multiple pages. 

// Assuming $entriesPerPage is the number of entries to display per page
// Assuming $currentPage is the current page number

// Calculate the OFFSET for the SQL query
$offset = ($currentPage - 1) * $entriesPerPage;

// Query to fetch entries for the current page
$query = "SELECT * FROM guestbook_entries LIMIT $entriesPerPage OFFSET $offset";
$result = mysqli_query($connection, $query);

// Display entries on the current page
while($row = mysqli_fetch_assoc($result)) {
    // Display entry content
}
