When you give feedback, use the correct tab (NOT the "Add Comment"
one!). And does this happen with any ftp server not under Windows? Any
firewalls or such between? Have you tried the PHP FTP extension instead?

I've tested it with the given snapshot:
PHP 5.3.3-dev (cli) (built: Feb 23 2010 08:21:46)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies
With the same results. Files are not always complete. :(

Description:
------------
When fopen/fwrite are used to upload a file, through ftp to a ftp server
running on windows, it is not always uploaded completely despite the
fact that fwrite returns that all bytes of the file are written.
I've testen the following scenarios with the attached code:
>From Ubuntu 9.10 to Bulletproof ftpd under windows xp (vmware).
(failed)
>From Ubuntu 9.10 to Serv-u ftpd under windows xp (vmware). (failed)
>From Ubuntu 9.10 to vsftpd on same machine. (ok)
Different hardware and network:
>From CentOS release 5 to Bulletproof ftpd on windows server (failed)
When using the ftp command it all works great.
Also tried the build-in ftp client from php and that works fine. It only
failed when using fopen/fwrite/file_put_contents.
Reproduce code:
---------------
$host = '192.168.1.34';
$user = 'marke';
$passwd = 'ebbers';
$path = '/';
$file = $argv[1];
$url='ftp://'.$user.':'.$passwd.'@'.$host.$path.$file;
$content = file_get_contents($file);
$handle = fopen($url, 'w');
$written = 0;
while ($written != strlen($content))
{
$write = fwrite($handle, substr($content, $written));
fflush($handle);
if($write){
$written .= $write;
echo "Written: ".$written.'\n';
}else{
break;
}
}
Expected result:
----------------
Output script: Written: 293346 (Test file is 293346 bytes.)
And a file on the ftp server of the same size.
Actual result:
--------------
Output script: Written: 293346 (Test file is 293346 bytes.)
A file on the server, but it is smaller. (and the sizes varies)
I've also a wireshark sniff available. The strange thing in the sniff is
that the every byte of the file is actually send, but by an unknown
reason there is tcp resend and the data in that resend is also the last
data in the file on the server.
