Question

我正在尝试使用数据库中的值生成CSV文件并强行下载。它工作正常，除了文件从服务器获取（不相关的）错误消息并将它们包含在CSV文件中。我该如何防止这种情况发生？

这是我的功能：

public function export($coupons_ids) {
        $coupons_ids = explode(',', (urldecode($coupons_ids)));

        $result = $this->cart_coupons->get_where_in('id',array_filter($coupons_ids, 'strlen'));

        header('Content-Type: text/csv; charset=utf-8');
        header('Content-Disposition: attachment; filename=coupons.csv');

        $output = fopen('php://output', 'w');

        fputcsv($output, array('id', 'name', 'start_date', 'end_date', 'promo', 'usage_limit'));

        foreach ($result as $row)
        {
            $id = $row->id;
            $name = $row->name;
            $start_date = $row->start_date;
            $end_date = $row->end_date;
            $usage_limit = $row->usage_limit;

            $active = '';
            switch($row->active)
            {
            case 0:
                $active = 'YES';
                break;
            case 1:
                $active = 'NO';
                break;
            }

            $promo = '$0';
            switch($row->promo_type)
            {
            case 0:
                $promo = '$' . $row->promo_value;
                break;
            case 1:
                $promo = $row->promo_value . '%';
                break;
            }

            $data = array('id' => $id, 'name' => $name, 'start_date' => $start_date, 'end_date' => $end_date, 'promo' => $promo, 'usage_limit' => $usage_limit);
            fputcsv($output, $data);
        }

        fclose($output);

    }

输出结果为：

我知道这个错误是什么，它与代码的功能完全无关且无关紧要。任何帮助表示赞赏。
