How can PHP developers efficiently handle pagination for a large number of entries in a guestbook, considering non-sequential IDs?

When dealing with a large number of entries in a guestbook with non-sequential IDs, PHP developers can efficiently handle pagination by using a combination of LIMIT and OFFSET clauses in SQL queries. By calculating the appropriate OFFSET based on the current page number and the number of entries per page, developers can retrieve the desired subset of entries for display. 

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

$offset = ($currentPage - 1) * $entriesPerPage;

$query = "SELECT * FROM guestbook ORDER BY id LIMIT $entriesPerPage OFFSET $offset";
// Execute the query and display the retrieved entries
