What steps can be taken to optimize the performance of pagination in PHP applications?

To optimize the performance of pagination in PHP applications, it is important to limit the amount of data fetched from the database by using SQL LIMIT and OFFSET clauses. Additionally, caching the results of the query can help reduce the load on the database. Finally, consider using AJAX to load data asynchronously to improve the user experience. 

// Calculate the LIMIT and OFFSET values based on the current page and items per page
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$itemsPerPage = 10;
$offset = ($page - 1) * $itemsPerPage;

// Query to fetch data with LIMIT and OFFSET
$query = "SELECT * FROM table_name LIMIT $itemsPerPage OFFSET $offset";
$result = mysqli_query($connection, $query);

// Display the data
while ($row = mysqli_fetch_assoc($result)) {
    // Display data here
}
