PhpExcel Save file to a folder

问题

I want to save the generated file to a folder located in the server, I tried the following code :

//save it to Excel5 format (excel 2003 .XLS file), change this to 'Excel2007' (and adjust the filename extension, also the header mime type)
//if you want to save it as .XLSX Excel 2007 format
        $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');
//force user to download the Excel file without writing it to server's HD
        $objWriter->save('‪C:\xampp\htdocs\timesheet\files\trials.xls');

but I keep getting the following error :

A PHP Error was encountered

What is the best way to save the document?
