Not much to say, just go to the code

The core is processing After completing the data, add the ob_end_clean() function before outputting the excel file; see the sample code for details, only part of the code is listed here

foreach ($licenseList as $key => $item) {
                    $objPHPExcel->setActiveSheetIndex(0)
                        ->setCellValue('A' . ($key + 2), $item["company_name"])
                        ->setCellValue('B' . ($key + 2), $item["user_name"])
                        ->setCellValue('C' . ($key + 2), $item["order_number"])
                        ->setCellValue('D' . ($key + 2), $item['apply_type']==2 ? 'official':'trial')
                        ->setCellValue('E' . ($key + 2), $item["license_key"])
                        ->setCellValue('F' . ($key + 2), $statusArr[$item['license_status']])->setCellValue('G' . ($key + 2), $item["user_email"])
                        ->setCellValue('H' . ($key + 2), date('y/m/d H:i:s', strtotime($item['insert_time'])));
                }

                $objPHPExcel->getActiveSheet()->setTitle('Simple');
                $objPHPExcel->setActiveSheetIndex(0);
                ob_end_clean();//解决乱码核心 就在此处添加此函数
                header('Content-Type: application/vnd.ms-excel');
                header('Content-Disposition: attachment;filename="test_list.xls"');
                header('Cache-Control: max-age=0');
                header('Cache-Control: max-age=1');
                header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
                header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT');
                header('Cache-Control: cache, must-revalidate');
                header('Pragma: public');

                $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
                $objWriter->save('php://output');
                exit;
