解决方法如下所示：

<?php include 'global.php'; $ids = $_GET['ids']; $sql = "select * from crm_cost_end where id in ( {$ids} )"; $result = $db->findAll($sql); //echo $result[1]['sn']; //创建一个excel对象 $objPHPExcel = new PHPExcel(); // Set properties $objPHPExcel->getProperties()->setCreator("ctos") ->setLastModifiedBy("ctos") ->setTitle("Office 2007 XLSX Test Document") ->setSubject("Office 2007 XLSX Test Document") ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.") ->setKeywords("office 2007 openxml php") ->setCategory("Test result file"); //set width $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(8); $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(10); $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(25); $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(12); $objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(50); $objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(10); $objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(12); $objPHPExcel->getActiveSheet()->getColumnDimension('H')->setWidth(12); $objPHPExcel->getActiveSheet()->getColumnDimension('I')->setWidth(12); $objPHPExcel->getActiveSheet()->getColumnDimension('J')->setWidth(30); //设置行高度 $objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(22); $objPHPExcel->getActiveSheet()->getRowDimension('2')->setRowHeight(20); //set font size bold $objPHPExcel->getActiveSheet()->getDefaultStyle()->getFont()->setSize(10); $objPHPExcel->getActiveSheet()->getStyle('A2:J2')->getFont()->setBold(true); $objPHPExcel->getActiveSheet()->getStyle('A2:J2')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('A2:J2')->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); //设置水平居中 $objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT); $objPHPExcel->getActiveSheet()->getStyle('A')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('B')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('D')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('F')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('G')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('H')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('I')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); // $objPHPExcel->getActiveSheet()->mergeCells('A1:J1'); // set table header content $objPHPExcel->setActiveSheetIndex(0) ->setCellValue('A1', '订单数据汇总 时间:' . date('Y-m-d H:i:s')) ->setCellValue('A2', '订单ID') ->setCellValue('B2', '下单人') ->setCellValue('C2', '客户名称') ->setCellValue('D2', '下单时间') ->setCellValue('E2', '需求机型') ->setCellValue('F2', '需求数量') ->setCellValue('G2', '需求交期') ->setCellValue('H2', '确认BOM料号') ->setCellValue('I2', 'PMC确认交期') ->setCellValue('J2', 'PMC交货备注'); // Miscellaneous glyphs, UTF-8 for ($i = 0; $i < count($result) - 1; $i++) { $objPHPExcel->getActiveSheet(0)->setCellValue('A' . ($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))->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>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'); ?>

在header() 前面加上ob_end_clean() 函数，清除缓冲区, 这样就不会乱码了!
