($i + 3), $result[$i]['id']); $objPHPExcel->getActiveSheet(0)->setCellValue('B' . ($i + 3), $result[$i]['realname']); $objPHPExcel->getActiveSheet(0)->setCellValue('C' . ($i + 3), $result[$i]['customer_name']); $objPHPExcel->getActiveSheet(0)->setCellValue('D' . ($i + 3), $OrdersData[$i]['create_time']); $objPHPExcel->getActiveSheet(0)->setCellValue('E' . ($i + 3), $result[$i]['require_product']); $objPHPExcel->getActiveSheet(0)->setCellValue('F' . ($i + 3), $result[$i]['require_count']); $objPHPExcel->getActiveSheet(0)->setCellValue('G' . ($i + 3), $result[$i]['require_time']); $objPHPExcel->getActiveSheet(0)->setCellValue('H' . ($i + 3), $result[$i]['product_bom_encoding']); $objPHPExcel->getActiveSheet(0)->setCellValue('I' . ($i + 3), $result[$i]['delivery_time']); $objPHPExcel->getActiveSheet(0)->setCellValue('J' . ($i + 3), $result[$i]['delivery_memo']); $objPHPExcel->getActiveSheet()->getStyle('A' . ($i + 3) . ':J' . ($i + 3))->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('A' . ($i + 3) . ':J' . ($i + 3))->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); $objPHPExcel->getActiveSheet()->getRowDimension($i + 3)->setRowHeight(16); } // Rename sheet $objPHPExcel->getActiveSheet()->setTitle('订单汇总表'); // Set active sheet index to the first sheet, so Excel opens this as the first sheet $objPHPExcel->setActiveSheetIndex(0); // Redirect output to a client's web browser (Excel5) <span style="color:#ff0000;">ob_end_clean();//清除缓冲区,避免乱码</span> header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="订单汇总表(' . date('Ymd-His') . ').xls"'); header('Cache-Control: max-age=0'); $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); $objWriter->save('php://output'); ?>
Add the ob_end_clean() function in front of header() to clear the buffer, so that there will be no garbled characters!
