Description:
------------
After executing a download process built with header() and print()
can't get any further output to browser page.

Reproduce code:
---------------
<?
$file = "my_file_to_dowload.txt";

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: no-store");
header("Cache-Control: private",true);
header("Content-Type: application/octet-stream");
header('Content-Disposition: attachment; filename="'.$file.'"' );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));

readfile($file)
  
echo("After I successfully downloaded the file, I can't see this line printed in browser window...");
?>


Expected result:
----------------
I expect that the code just after
readfile($file)
is being executed.
In this case I wish to see in browser window the message sent with echo
().

Actual result:
--------------
Anything in php code which is after the block

header("string");
.....
readfile("string");

is ignored.
Exactly like the code was:

header("string");
....
readfile("string");
exit();

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

HTTP offers only one output stream -> You\'re writing to the file using your echo statement.
