What are the best practices for optimizing the display of a large dataset in a PHP application?

When displaying a large dataset in a PHP application, it is important to optimize the display for performance and user experience. One way to achieve this is by implementing pagination, which allows the data to be displayed in smaller, more manageable chunks. This can help reduce load times and prevent overwhelming the user with too much information at once. 

<?php

// Assuming $data is the large dataset to be displayed

// Set the number of items to display per page
$items_per_page = 10;

// Get the current page number from the query string
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate the starting index for the data slice
$start = ($page - 1) * $items_per_page;

// Slice the data array to display only the items for the current page
$data_slice = array_slice($data, $start, $items_per_page);

// Display the data slice
foreach ($data_slice as $item) {
    echo $item . "<br>";
}

// Display pagination links
$total_pages = ceil(count($data) / $items_per_page);
for ($i = 1; $i <= $total_pages; $i++) {
    echo "<a href='?page=$i'>$i</a> ";
}
?>
