How can memory usage and CPU processing affect the rendering of PHP-generated tables?

Memory usage and CPU processing can affect the rendering of PHP-generated tables by slowing down the rendering process and potentially causing the server to run out of resources, leading to performance issues. To optimize rendering, you can limit the amount of data being processed at once, use pagination to load data in smaller chunks, and optimize your code for efficiency. 

// Example of implementing pagination in PHP-generated table rendering

$page = isset($_GET['page']) ? $_GET['page'] : 1;
$items_per_page = 10;
$start_index = ($page - 1) * $items_per_page;

// Query database for data using LIMIT and OFFSET
$query = "SELECT * FROM table_name LIMIT $items_per_page OFFSET $start_index";
$result = mysqli_query($connection, $query);

// Loop through and render table rows
while ($row = mysqli_fetch_assoc($result)) {
    // Render table row here
}

// Pagination links
$total_rows = mysqli_num_rows(mysqli_query($connection, "SELECT * FROM table_name"));
$total_pages = ceil($total_rows / $items_per_page);

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