Bug description:filesize and reafile incosistencies with pdf file
Description:
------------
With some PDF files (not all), the filesize function report a file size
that is
not representative of the size of the file produced by readfile.
The filesize gives the same filesize as the original file. But the readfile
doesn't give the exact same content as the original file, making it
slightly
bigger.
This results in some part of the file being cut if you include the filesize
in the
header.
I can reproduce this bug on 2 servers,
Test script:
---------------
header('Content-Type: application/pdf');
header("Content-Length: ".filesize($file));
readfile($file);
exit();
// THIS CODE PRODUCE THE SAME PROBLEM
ob_start();
readfile($file);
$output = ob_get_clean();
header('Content-Type: application/pdf');
header("Content-Length: ".strlen($output));
echo $output;
exit();
Expected result:
----------------
Expect the filesize to return the right filesize. Or the readfile to output
the
exactly same content as the original file.
Actual result:
--------------
The filesize function report a file size that is not representative of the
size of
the file produced by readfile.
