I guess what threw me in the wrong direction is that it was still working fine with some PDFs. ------------------------------------------------------------------------ [2011-04-13 10:44:50] cataphract@php.net Almost certainly bogus, but in any case, what is this extra data that's causing the discrepancy? What's its place in the output stream? Most likely there's whitespace or a BOM mark in the script (or an included script). ------------------------------------------------------------------------ [2011-04-12 21:55:16] gabriel at justbull dot com 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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54518&edit=1
