对word直接从数据库查询进行下载

function save($word_name)
	{
	 
		echo "</html>";
		$data = ob_get_contents();
		ob_end_clean();
		$this->wirtefile ($word_name,$data);
	}
	 
	function wirtefile ($word_name,$data)
	{
		$path = 'public/uploads/'.$word_name;
		$file = fopen($path,"wd");
		fwrite($file,$data);
		fclose($file);
		$file = fopen($path,"r");
		Header("Content-type: application/octet-stream");
		Header("Accept-Ranges: bytes");
		Header("Accept-Length: ".filesize($path));
		Header("Content-Disposition: attachment; filename=".basename($path));
		echo fread($file, filesize($path));
		fclose($file);
		unlink($path);
		$this->index();
