New Comment:
Are you absolutely SURE you really updated PHP correctly??
We've seen this so many times that it's getting annoying,
people report bugs that are fixed, and after couple
of comments here, they find out that they really had old
version there..usually of php4ts.dll.
To be 100% you really get it updated, remove ALL the php
related files from your machine, reboot (yes, reboot!),
and then install the snapshot.

I have found this bug in 4.3.0, searched matching bug reports and they
said the bug is fixed in the latest stable CVS snap. I have downloaded
and installed today's latest version, the fix is mentioned in the
news.txt, but the bug is still there.
Here are my test files for a short reproducing script:
file test.txt:
(saved in dos format, ie. newlines are CRLF/\r\n):
------------------------------
This is a test file
in win32 / dos format
ie. lines end with CRLF
resp. \r\n
------------------------------
file test.php
------------------------------
<?php
$fp = fopen('test.txt', 'r');
$contents = fread($fp, 30);
fseek($fp, ftell($fp));
$contents .= fread($fp, 30);
echo $contents;
echo "\n\n";
var_dump(strpos($contents, "\r"));
?>
------------------------------
Output:
------------------------------
This is a test file
in win32 // dos format
ie. lines end wit
bool(false)
------------------------------
It can be seen that fseek() or ftell() don't work as expected: the '/'
character is read twice.
Furthermore, fread() doesn't return \r characters. I also have tested
this for fgetc() - \r is not read.
A strange thing is that this bug doesn't occurr in the newest php5/ze2
snapshot.
