How can PHP developers efficiently manage and display large amounts of data in a web application?

To efficiently manage and display large amounts of data in a web application, PHP developers can use pagination to break up the data into smaller chunks that can be easily loaded and displayed. By implementing pagination, users can navigate through different pages of data without overwhelming the server or slowing down the application. 

// Assuming $data is the large dataset to be displayed
$items_per_page = 10; // Number of items to display per page
$total_items = count($data); // Total number of items in the dataset
$total_pages = ceil($total_items / $items_per_page); // Calculate total number of pages

$page = isset($_GET['page']) ? $_GET['page'] : 1; // Get current page number from query parameter
$start = ($page - 1) * $items_per_page; // Calculate starting index for current page
$end = $start + $items_per_page; // Calculate ending index for current page

// Display data for current page
for ($i = $start; $i < $end && $i < $total_items; $i++) {
    echo $data[$i] . "<br>";
}

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