How can PHP developers optimize the performance of pagination functionality in their applications?

To optimize the performance of pagination functionality in PHP applications, developers can limit the amount of data fetched from the database by using SQL LIMIT and OFFSET clauses. This helps reduce the amount of data transferred and processed, resulting in faster page load times. Additionally, caching the query results can further improve performance by reducing the number of database calls. 

// Example code snippet for optimizing pagination performance

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

// Execute the query with LIMIT and OFFSET clauses to fetch only the necessary data
$query = "SELECT * FROM products LIMIT $itemsPerPage OFFSET $offset";
$result = mysqli_query($connection, $query);

// Process the query results and display the paginated data
while ($row = mysqli_fetch_assoc($result)) {
    // Display the data
}
