封装一个PHPExcel操作类

导出：

getProperties()->setCreator("lws");
        $objExcel->getProperties()->setLastModifiedBy("lws");
        $objExcel->getProperties()->setTitle('Office '.$type.' XLS Document');
        $objExcel->getProperties()->setSubject('Office '.$type.' XLS Document');
        $objExcel->getProperties()->setDescription('for Office '.$type.' XLS');
        $objExcel->getProperties()->setKeywords('office '.$type.' php');
        $objExcel->getProperties()->setCategory("FOR ANTAG");
        $objExcel->setActiveSheetIndex(0);

        $str = 'abcdefghijklmnopqrstuvwxyz';
        $head_scope = $str[0].'1:'.$str[count($flagarr)-1].'1'; //表头范围 如：a1:f1
        foreach ($flagarr as $k => $v){
            //设置表头
            $objExcel->getActiveSheet()->setCellValue($str[$k].'1', "$v[0]");

            //设置自适应宽度
            $objExcel->getActiveSheet()->getColumnDimension($str[$k])->setAutoSize(true);
        }

        //添加数据
        for ($i=0; $i < count($list); $i++) {
            $j = $i + 2;
            foreach ($flagarr as $k => $v){
                $objExcel->getActiveSheet()->setCellValue($str[$k].$j,' '.$list[$i][$v[1]]); //前面加空格 防止数字文本被转换为科学计数法
            }
        }

        //设置表头背景色
        $objExcel->getActiveSheet()->getStyle($head_scope)->getFill()->setFillType(\PHPExcel_Style_Fill::FILL_SOLID);
        $objExcel->getActiveSheet()->getStyle($head_scope)->getFill()->getStartColor()->setARGB($headcolor);

        //设置表头文字颜色
        $styleArray = array(
            'font'  => array(
                'color' => array('rgb' => $head_fontcolor),
            ));
        $objExcel->getActiveSheet()->getStyle($head_scope)->applyFromArray($styleArray);

        //设置表头和表尾
        $objExcel->getActiveSheet()->getHeaderFooter()->setOddHeader('&L&BPersonal cash register&RPrinted on &D');
        $objExcel->getActiveSheet()->getHeaderFooter()->setOddFooter('&L&B' . $objExcel->getProperties()->getTitle() . '&RPage &P of &N');

        //设置页方向和规模
        $objExcel->getActiveSheet()->getPageSetup()->setOrientation(\PHPExcel_Worksheet_PageSetup::ORIENTATION_PORTRAIT);
        $objExcel->getActiveSheet()->getPageSetup()->setPaperSize(\PHPExcel_Worksheet_PageSetup::PAPERSIZE_A4);
        $objExcel->setActiveSheetIndex(0);
        $timestamp = time();
        ob_end_clean();

        //导出excel
        if ($type == '2003'){
            header("Content-Type: application/vnd.ms-excel; charset=utf-8");
            header('Content-Type: application/vnd.ms-excel');
            header('Content-Disposition: attachment;filename='.$filename.'.xls');
            header('Cache-Control: max-age=0');
            $objWriter = \PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');
            $objWriter->save('php://output');
            exit;
        }else{
            header("Content-Type: application/vnd.ms-excel; charset=utf-8");
            header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
            header('Content-Disposition: attachment;filename='.$filename.'.xlsx');
            header('Cache-Control: max-age=0');
            $objWriter = \PHPExcel_IOFactory::createWriter($objExcel, 'Excel2007');
            $objWriter->save('php://output');
            exit;
        }
    }
}

导出测试：

public function daochu_test(){
    $list = [
          [
              'name'=>'李维山',
              'sex'=>'男',
              'age'=>'18',
              'content'=>'gzstatu'
          ]
    ];
    $flagarr = [
      ['姓名','name'],
      ['性别','sex'],
      ['年龄','age'],
      ['说明','content']
    ];
    $ex = new PHPExcelService();
    $ex->excelout($list,$flagarr,'导出excel测试');
}
