//导出调查评议的数据
    public function diaocha(){
        $xlsName = '表格形式 调查评议 信息';
        $xlsTitle = array(
            array('ming','试题所属分类'),

            $xlsData[$k]['ping'] = round($xlsData[$k]['fenshu']/$xlsData[$k]['renshu'],2);//总平均分
            //良好，一般，很差
            $liang = 0;

                            break;
                    }

            $xlsData[$k]['liang'] = round($liang/$tishu,2)*100;

        }
//        dump($xlsData);die();
        exportExcel($xlsName,$xlsTitle,$xlsData);
    }

exportExcel方法是放在function.php里的  此方法可以导入导出

//导出excel表格
function exportExcel($expTitle,$expCellName,$expTableData){
    $xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称
    $fileName = $_SESSION['account'].date('_YmdHis');//or $xlsTitle 文件名称可根据自己情况设定
    $cellNum = count($expCellName);
    $dataNum = count($expTableData);
    vendor("PHPExcel.PHPExcel");

    $objPHPExcel = new PHPExcel();
    $cellName = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','AA','AB','AC','AD','AE','AF','AG','AH','AI','AJ','AK','AL','AM','AN','AO','AP','AQ','AR','AS','AT','AU','AV','AW','AX','AY','AZ','BA','BB','BC','BD','BE','BF','BG','BH','BI');

    //$objPHPExcel->getActiveSheet(0)->mergeCells('A1:'.$cellName[$cellNum-1].'1');//合并单元格
    // $objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', $expTitle.'  Export time:'.date('Y-m-d H:i:s'));
    for($i=0;$i<$cellNum;$i++){
        $objPHPExcel->setActiveSheetIndex(0)->setCellValue($cellName[$i].'1', $expCellName[$i][1]);
    }
    // Miscellaneous glyphs, UTF-8
    for($i=0;$i<$dataNum;$i++){
        for($j=0;$j<$cellNum;$j++){
            $objPHPExcel->getActiveSheet(0)->setCellValue($cellName[$j].($i+2), $expTableData[$i][$expCellName[$j][0]]);
        }
    }

    header('pragma:public');
    header('Content-type:application/vnd.ms-excel;charset=utf-8;name="'.$xlsTitle.'.xls"');
    header("Content-Disposition:attachment;filename=$fileName.xls");//attachment新窗口打印inline本窗口打印
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save('php://output');
    exit;
