Excel 文件未使用带有动态数据的 PHPExcel 库下载

Question

当我单击导出按钮时，它会转到我的export_inquiry() 函数，我已经设置了来自 DB 表的数组，并使用此动态数组数据下载了 excel 文件。但是，现在它给我带来了错误 无法访问此站点 http://www.example.com/project_name/admin/order/export_inquiry 的网页可能暂时关闭，或者它可能已永久移动到新网址。

ERR_INVALID_RESPONSE。

我正在使用CodeIgniter 中的PHPExcel 库来下载excel 文件。下面是我的excel导出代码。

public function export_inquiry()
{
    ini_set('display_startup_errors',1);
    ini_set('display_errors',1);
    error_reporting(E_ALL);


    $this->load->library('phpexcel/PHPExcel');
    $object = new PHPExcel();

      $object->setActiveSheetIndex(0);

      $table_columns = array("DATE", "ID", "CustomerReference", "InvoiceName", "PickUpCity", "PickUpDate");

      $column = 0;

      foreach($table_columns as $field)
      {
       $object->getActiveSheet()->setCellValueByColumnAndRow($column, 1, $field);
       $column++;
      }

      $employee_data  =array(
        array(
            'order_date' => '2018-05-23 22:35:36',
            'id' => 17,
            'customerreference' => '',
            'invoice_name' => 'Troy Design and Manufacturing',
            'pick_up_city' => 'Gothenburg',
            'pick_up_date' => '2018-07-02'
        ),
        array(
            'order_date' => '2018-05-28 02:51:58',
            'id' => 19,
            'customerreference' => '',
            'invoice_name' => 'Hollingsworth Distribution Systems',
            'pick_up_city' => 'Gothenburg',
            'pick_up_date' => '2018-07-02'
        ),
        array(
            'order_date' => '2018-05-28 04:39:23',
            'id' => 20,
            'customerreference' => '',
            'invoice_name' => 'Motherson Automotive (FSP-1)',
            'pick_up_city' => 'Gothenburg',
            'pick_up_date' => '2018-07-02'
        )
    );

      $excel_row = 2;
      foreach($employee_data as $key => $row)
      {
       $object->getActiveSheet()->setCellValueByColumnAndRow(0, $excel_row, $row['order_date']);
       $object->getActiveSheet()->setCellValueByColumnAndRow(1, $excel_row, $row['id']);
       $object->getActiveSheet()->setCellValueByColumnAndRow(2, $excel_row, $row['customerreference']);
       $object->getActiveSheet()->setCellValueByColumnAndRow(3, $excel_row, $row['invoice_name']);
       $object->getActiveSheet()->setCellValueByColumnAndRow(4, $excel_row, $row['pick_up_city']);
       $object->getActiveSheet()->setCellValueByColumnAndRow(5, $excel_row, $row['pick_up_date']);
       $excel_row++;
      }

      $object_writer = PHPExcel_IOFactory::createWriter($object, 'Excel5');
      header('Content-Type: application/vnd.ms-excel');
      header('Content-Disposition: attachment;filename="Employee Data.xls"');
      $object_writer->save('php://output');
}

谁能帮我解决这个问题？ 提前致谢。
