Question

我已经设法使用php创建了一个excel文档但是我每次打开文档时都会收到错误，即使其他一切都很好。错误是the file you are trying to open is in different format than specified by the file extension ...

我要导出到excel的代码：

public function actionExportToExcel() {

        //header('Content-type: text/csv');
        header('Content-Disposition: attachment; filename="project-report-' . date('YmdHi') .'.xls"');
        header("Content-Type: application/ms-excel");

        $model=new ViewWebprojectreport('search');
        $model->unsetAttributes();  // clear any default values

        if(Yii::app()->user->getState('exportModel'))
            $model=Yii::app()->user->getState('exportModel');


        $dataProvider = $model->search(false);
        $dataProvider->pagination->pageSize = $model->count();
        // csv header
        echo    ViewWebprojectreport::model()->getAttributeLabel("StartDATE")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("PROJECT")."\t".
                "Survey Number\t".
                ViewWebprojectreport::model()->getAttributeLabel("ActualEndDate")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("OFFICE")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("PERCENT")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("PERCENTPlanned")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("KM")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("KMPlanned")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("COUNTRY")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("AREA")."\t".
                ViewWebprojectreport::model()->getAttributeLabel("ASAAREA").
                " \r\n";
        // csv data
        foreach ($dataProvider->getData() as $data) {
            //if you want all data use this looop
            /*foreach ($data as $key => $value) {
                echo $value.",";
            }
            echo "\r\n";*/
            echo "$data->StartDATE\t$data->PROJECT\t".$data->PROJCODE . $data->PROJID ."\t$data->ActualEndDate\t$data->OFFICE\t$data->PERCENT\t$data->PERCENTPlanned\t$data->KM\t$data->KMPlanned\t$data->COUNTRY\t$data->AREA\t$data->ASAAREA\t\r\n";
        }


    }

我不想导出为csv，而是直接导入excel格式文件。我错过了什么？

Answer 1

这是因为该文件实际上基本上只是一个带有XLS扩展名的CSV文件，以便在Excel中打开它。有关详细信息，请参阅此Microsoft文档：http://support.microsoft.com/kb/948615 - 它出现在新版本的Excel中。年纪较大的人会乐意出口他们。

这样做的原因是因为导出CSV文件比使用Excel文件简单得多。我想在某个时候写一个合适的Excel导出器，但这需要时间来阅读和理解Excel文件格式，我还没有机会这样做。

一个选项只是将文件名重命名为.csv，并保持用户界面说它是一个Excel文件（Excel非常乐意阅读csv文件）。鉴于Windows倾向于隐藏文件扩展名，这似乎是一个相当有吸引力的选择。

这对解决各种excel问题很有帮助 - link

请告诉我是否可以为您提供更多帮助。

我使用过PHPExcel

    $objPHPExcel = new PHPExcel();
    spl_autoload_register(array('YiiBase', 'autoload'));

    $objPHPExcel->getProperties()->setCreator(Yii::app()->user->__userInfo['name'])
        ->setLastModifiedBy(Yii::app()->user->__userInfo['name'])
        ->setTitle("Weekly Status")
        ->setSubject("Weekly Status");

    $sheet = $objPHPExcel->setActiveSheetIndex(0);
    $highestRow = $sheet->getHighestRow();
    $highestColumn = $sheet->getHighestColumn();

    $model=new ViewWebprojectreport('search');
    $model->unsetAttributes();  // clear any default values

    if(Yii::app()->user->getState('exportModel'))
        $model=Yii::app()->user->getState('exportModel');


    $dataProvider = $model->weeklystatus(array(),true,false);
    $dataProvider->pagination->pageSize = $model->count();

    //data
    foreach ($dataProvider->getData() as $data) {
        //if you want all data use this looop
        $highestColumn = "A";
        foreach ($data as $key => $value) {
            if(! in_array($key,array("id","PROCESSOR","DEPTCODE","PERCENTPlanned","MCSALE"))){
                if($key == "name")
                    $key = "Client";
                else
                    $key = ViewWebprojectreport::model()->getAttributeLabel("$key");
                if($highestRow == 1){
                    $sheet->setCellValue($highestColumn.$highestRow,$key);
                    //Yii::log($key,"ERROR");
                }
                //echo $value.",";
                if($highestRow == 1){
                    $highestRow++;
                    $sheet->setCellValue($highestColumn.$highestRow,$value);
                    $highestRow--;
                }else
                    $sheet->setCellValue($highestColumn.$highestRow,$value);

                $highestColumn++;
            }


        }
        //Yii::log($highestRow,"ERROR");
        if($highestRow == 1)
            $highestRow++;

        $highestRow++;
        //echo "\r\n";*/
        //echo "$data->StartDATE\t$data->ProjectEndDate\t$data->PROJECT\t".$data->PROJCODE . $data->PROJID ."\t$data->ActualEndDate\t$data->PROCESSOR\t$data->OFFICE\t$data->DEPTCODE\t$data->PERCENT\t$data->PERCENTPlanned\t$data->KM\t$data->KMPlanned\t$data->MC\t$data->MCSALE\t$data->CATEGORY\t$data->COUNTRY\t$data->AREA\t$data->PROJINFO\t$data->REGION\t$data->ASAAREA\t\r\n";
    }


    $filename = $_GET['type'].'statusreport_'.date('Y-m-d_H-i-s_T').'.xls';

    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="'.$filename.'"');
    header('Cache-Control: max-age=0');
    // If you're serving to IE 9, then the following may be needed
    header('Cache-Control: max-age=1');

    // If you're serving to IE over SSL, then the following may be needed
    //header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
    header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
    header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
    header ('Pragma: public'); // HTTP/1.0

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save(Yii::app()->params['exportToDir'].$filename);
    $objWriter->save('php://output');
    Yii::app()->end();
