    use PHPExcel_IOFactory;
    use PHPExcel;  


    $PHPExcel = new PHPExcel(); //實例化PHPExcel類
    $PHPSheet = $PHPExcel->getActiveSheet(); //獲得當前活動sheet的操作對象
    $PHPSheet->setTitle('Sheet'); //給當前活動sheet設置名稱
    $i = 1;
    $PHPSheet->setCellValue('A'.$i,'today rank')
             ->setCellValue('B'.$i,'domain');
    foreach ($result as $key => $item) {
        $i++;
        $PHPSheet->setCellValue('A'.$i, $item['today_rank'])
             ->setCellValue('B'.$i, $item['domain']);
    }
    $PHPWriter = PHPExcel_IOFactory::createWriter($PHPExcel,'Excel5');
    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');//告訴瀏覽器輸出07Excel文件
    header('Content-Disposition: attachment;filename="xxxx.xlsx"');
    header('Cache-Control: max-age=0');//禁止緩存
