一般來(lái)說(shuō),下載txt會(huì)直接打開,把下面的代碼放入到下載頁(yè)面中,就提示下載并可以進(jìn)度保存了!文件位置（eDownSysclassDownSysFun.php）
找到如下代碼（帝國(guó)CMS7.5 大概203行左右）
//下載
Header("Content-type: application/octet-stream");
//Header("Accept-Ranges: bytes");
//Header("Accept-Length: ".$filesize);
Header("Content-Disposition: attachment; filename=".$filename);
echo ReadFiletext($file);

改成如下代碼：（注意UTF8編碼請(qǐng)用編輯器打開修改）
//下載
$filesize = filesize($file);
Header('Pragma: public');
Header('Last-Modified:'.gmdate('D, d M Y H:i:s') . ' GMT');
Header('Cache-Control: no-store, no-cache, must-revalidate');
Header('Cache-Control: pre-check=0, post-check=0, max-age=0');
Header('Content-Transfer-Encoding: binary');
Header('Content-Encoding: none');
Header("Content-type: application/octet-stream");
Header("Content-Disposition: attachment; filename=".$filename);
Header('Content-length: '.$filesize);
echo ReadFile($file);
