解决PHP文件（word/excel）下载 内容打开乱码问题

编码转换不一定有用，一般可以解决文件名乱码问题

iconv('utf-8','gb2312',$filename);

 

具体代码如下：

   header("Pragma: public");

        header("Cache-control: max-age=".$expire);

        //header('Cache-Control: no-store, no-cache, must-revalidate');

        header("Expires: " . gmdate("D, d M Y H:i:s",time()+$expire) . "GMT");

        header("Last-Modified: " . gmdate("D, d M Y H:i:s",time()) . "GMT");

        header("Content-Disposition: attachment; filename=".$showname);

        header("Content-Length: ".$length);

        header("Content-type: ".$type);

        header('Content-Encoding: none');

        header("Content-Transfer-Encoding: binary" );

//**********************************

        ob_clean();

    flush();

//*********************************

        readfile($filename);

 

注意上面的两行代码

ob_clean();

flush();
