How can the number of HTTP requests be optimized in PHP applications with a large number of data records?

When dealing with a large number of data records in PHP applications, one way to optimize the number of HTTP requests is by implementing pagination. This allows the application to retrieve and display data in smaller, more manageable chunks, reducing the need for multiple requests to fetch all records at once. 

// Example of implementing pagination in PHP to optimize HTTP requests

// Define the number of records to display per page
$records_per_page = 10;

// Calculate the offset based on the current page number
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($page - 1) * $records_per_page;

// Query the database with the calculated offset and limit
$query = "SELECT * FROM data_table LIMIT $offset, $records_per_page";
$result = mysqli_query($connection, $query);

// Display the data records
while ($row = mysqli_fetch_assoc($result)) {
    // Display data here
}

// Add pagination links
$total_records = // Query to get total number of records
$total_pages = ceil($total_records / $records_per_page);

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