You can send the data to the server however you'd like (using $_POST, AJAX, etc.). Once the data arrives at the server, though, this is how I would go about sending the data to a CSV file.

$serialized_data = $_POST['some_data_array'];

if($downloadFile) // simple condition
{

    $fp = fopen('php://memory', 'w+'); // open up write to memory


    foreach($serialized_data  as $row) // $serialized_data represents what you sent to the server from JS
    {
        fputcsv($fp, $row);
    }

    rewind($fp);
    $csvFile = stream_get_contents($fp);
    fclose($fp);

    header('Content-Type: text/csv');
    header('Content-Length: '.strlen($csvFile));
    header('Content-Disposition: attachment; filename="yourFile.csv"');
    exit($csvFile);
}
