Slim基于PSR-7。以下是生成和下载CSV文件（未测试）的示例伪代码：

public function downloadCsvAction(Request $request, Response $response): ResponseInterface
{
    $query = mysqli_query($this->con, "SELECT * FROM `tbl_brands`");

    $filename = "sampledata.csv";

    $stream = fopen('php://memory', 'w+');

    $flag = false;
    while ($row = mysqli_fetch_assoc($query)) {
        if (!$flag) {
            // add field/column names as first row
            fputcsv($stream, array_keys($row), ",", '"');
            $flag = true;
        }
        fputcsv($stream, array_values($row), ",", '"');
    }
    rewind($stream);

    $response = $response->withHeader('Content-Type', 'text/csv');
    $response = $response->withHeader('Content-Disposition', 'attachment; filename="' . $filename . '"');

    return $response->withBody(new \Slim\Http\Stream($stream));
}
