How can pagination and limiting the number of displayed records help improve the user experience when dealing with a large dataset in PHP?

When dealing with a large dataset in PHP, pagination and limiting the number of displayed records can help improve the user experience by reducing the amount of data loaded at once, making the page load faster and more responsive. This approach also helps users navigate through the dataset more easily by breaking it down into smaller, manageable chunks. 

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

$limit = 10; // Number of records to display per page
$page = isset($_GET['page']) ? $_GET['page'] : 1; // Get current page number, default to 1 if not set

$start = ($page - 1) * $limit; // Calculate starting index for records
$end = $start + $limit; // Calculate ending index for records

$paginatedData = array_slice($data, $start, $limit); // Get subset of data to display on current page

// Display paginated data
foreach ($paginatedData as $record) {
    echo $record . "<br>";
}

// Pagination links
$totalPages = ceil(count($data) / $limit);
for ($i = 1; $i <= $totalPages; $i++) {
    echo "<a href='?page=$i'>$i</a> ";
}
