Question

我正在使用Zend上的PHPExcel创建包含UTF-8编码数据的Excel报告。当我下载并尝试在Excel中打开它时，它适用于本地环境但我收到以下错误：来自live sever / production的“不正确的文件格式”。任何帮助/参考将不胜感激。

这是我用来下载xls文件的代码：

public function getCsv($data, $filename = false)
 {
     /**
      * generate a file name using unixTimeStamp
      * @var string $tmpfname
      */
      if ($filename)
      {
          $tmpfile =    "/tmp/".$filename. "-". date('Y-m-d_H:i:s') . ".csv";
          $name = str_replace(' ','',$filename)."-".date('Y-m-d_H:i:s') . ".xls";
      }
      else
      {
          $tmpfile = "/tmp/report". "_". date('Y-m-d_H:i:s') . ".csv";
          $name = "report-".date('Y-m-d_H:i:s') . ".xls";
      }
      /**
       * open Temporary file name in write mode
       * @var object $fp
       */
       $fp = fopen($tmpfile, "w");
       /**
        * foreach datas write to csv
        */
       foreach ($data as $fields)
           fputcsv($fp, $fields, ',', '"');

       /**
        * close file
        */
        fclose($fp);

        try
        {
            $objReader = PHPExcel_IOFactory::createReader('CSV');
            $objPHPExcel = $objReader->load($tmpfile);
            $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

            //set Header Content Type as application/csv
            header("Content-Type: application/vnd.ms-excel; charset=utf-8");
            header("Content-Disposition: attachment; filename=$name");
            $objWriter->save('php://output');
        }
        catch (Exception $e)
        {
            echo $e->getMessage();
        }

        exit;
    }

您必须在保存之前使用此行：

ob_end_clean();

打开下载的文件错误“错误的文件格式”时出现PHPExcel错误
