Thinkphp框架下PHPExcel实现excel数据的批量化导入

Posted 2020-09-18 纸上得来终觉浅，绝知此事要躬行

第一步：下载官方的phpExcel文件，下载地址https://github.com/PHPOffice/PHPExcel

 

第二步：解压打开，将PHPExcel\\Classes\\全部文件拷贝到thinkhp项目的根目录\\ThinkPHP\\Library\\Vendor\\,如下图所示

 

第三步（导入）：

html代码如下：

<form action="{:U(\'Index/impUser\')}" method="post" enctype="multipart/form-data">
      <input type="file" name="import"/>
      <input type="submit" value="提交"/>
</form>

 

控制器层实现如下代码：

function impUser(){
        if (!empty($_FILES)) {
            //import("@.ORG.UploadFile");
            $config=array(
                \'exts\'=>array(\'xlsx\',\'xls\'),
                \'rootPath\'=>"./Public/",
                \'savePath\'=>\'Upload/\',
                //\'autoSub\'    =>    true,
            );
            $upload = new \\Think\\Upload($config);
            
            if (!$info=$upload->upload()) {
                $this->error($upload->getError());
            } /*else {
                //$info = $upload->getUploadFileInfo();   
            }
            */
            
            vendor("PHPExcel.PHPExcel");
            $file_name=$upload->rootPath.$info[\'import\'][\'savepath\'].$info[\'import\'][\'savename\'];
            // var_dump($file_name);
            // exit;
            $objReader = \\PHPExcel_IOFactory::createReader(\'Excel5\');
            $objPHPExcel = $objReader->load($file_name,$encode=\'utf-8\');
            $sheet = $objPHPExcel->getSheet(0);
            $highestRow = $sheet->getHighestRow(); // 取得总行数
            $highestColumn = $sheet->getHighestColumn(); // 取得总列数
            for($i=4;$i<=$highestRow;$i++)
            {
                $data[\'name\'] = $objPHPExcel->getActiveSheet()->getCell("B".$i)->getValue();
                $data[\'age\'] = $objPHPExcel->getActiveSheet()->getCell("C".$i)->getValue();
                $data[\'school\']= $objPHPExcel->getActiveSheet()->getCell("D".$i)->getValue();=$data[\'jion_time\']= gmdate("Y-m-d H:i:s", \\PHPExcel_Shared_Date::ExcelToPHP($objPHPExcel->getActiveSheet()->getCell("M".$i)->getValue()));//其中gmdate函数是对excel表格中的时间进行格式化处理


                M(\'detail_config\')->add($data);
                    
            }
            $this->success(\'导入成功！\',\'index\');
        }else
        {
            $this->error("请选择上传的文件");
        }
    }

 

第四步（导出）：

HTML代码如下：

<a href="{:U(\'Index/expUser\')}">导出数据并生成excel</a>

 

控制器层实现如下代码：

//统计数据自动化导出EXCEL
    public function exportExcel($expTitle,$expCellName,$expTableData){
        $xlsTitle = iconv(\'utf-8\', \'gb2312\', $expTitle);//文件名称
        $fileName = $_SESSION[\'admin\'][\'username\'].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\');

        $objPHPExcel->getActiveSheet(0)->mergeCells(\'A1:\'.$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].\'2\', $expCellName[$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+3), $expTableData[$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;
    }
    
    public function expUser(){//导出Excel
        $xlsName  = "admin";
        $xlsCell  = array(
        array(\'id\',\'序列号\'),
        array(\'name\',\'姓名\'),
        array(\'age\',\'年龄\'),
        array(\'school\',\'学校\')
        );
        $xlsModel = M(\'Index\');

        $xlsData  = $xlsModel->Field(\'id,name,age,school\')->select();
        
        $this->exportExcel($xlsName,$xlsCell,$xlsData);
            
    }

以上步骤即可实现数据批量化的导入导出；
