ms excel文件无法在PHPExcel中加载

Question

ms excel文件无法在PHPExcel中加载，但是当我在linux中使用libreoffice创建excelsheets时，它会加载并上传到数据库中。

        $temp=$_FILES['file']['tmp_name'];
        $destination = "/var/www/html/recovery";
        move_uploaded_file($temp,$destination."/"."recovery"."."."xlsx");
        chmod("/var/www/html/recovery/recovery.xlsx", 0777);
        $inputFileName ='recovery.xlsx';

  try 
  {
         $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
         $objReader = PHPExcel_IOFactory::createReader($inputFileType);
         $objPHPExcel =$objReader->load($inputFileName);

   }
   catch(Exception $e) 
   {
    die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
   }

  $allDataInSheet = $objPHPExcel->getActiveSheet()- >toArray(null,true,true,true);
  $arrayCount = count($allDataInSheet);  

我使用PHPExcel上传所有类型的excel文件。
