Hi,

I think know a bug in php, i have an file in folder (/home/user/file/file.ext), when i try download (with my script), the php insert a "\n" at start of the file.

I try to remove the \n, dont resolve the problem.

I'm sorry for my bad english. If this is not bug ... sorry ... i try find a solution in the google but not happen.





Reproduce code:
---------------
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: $ctype");
header("Content-Disposition: attachment; filename=\"".$nm_layout."\";");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".$tm_layout);
set_time_limit(0);
readerfile($bn_layout); 

/* the variables have a value, the download is finished and all the content of the file is correct, but the "\n" broken the file */

Expected result:
----------------
Correct file content

Actual result:
--------------
Correct file content but with "\n" at start.
