Works fine with latest CVS:
<?php
$fp = @fopen('/etc/passwd-', 'r' );
var_dump($fp, feof( $fp ));
?>
prints bool(false) twice as it should.

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP --
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php
If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

I argue that it is a bug and that it was already addressed in a similar
problem
see http://bugs.php.net/bug.php?id=25939.
Basically while in the while( feof() ) loop the socket goes away due to
network failure and the stream is no longer there. This causes an
infinite loop in 4.3.4 because feof() would not return TRUE. In 4.3.5
they changed this behavior to return TRUE on socket failure. This would
be similar to saying the file handle is not valid and there is nothing
there feof() thus we are at the end of nothing. I guess you could say
we are at begining of nothing.
I understand this is more of a symantics issue than a bug. If you
google 'feof infinite php' you will see that there are a lot of people
that get stung by this issue. Maybe it should be changed to get around
a common problem.
What do you think?

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.
Thank you for your interest in PHP.
feof() does exactly what it\'s supposed to.

Description:
------------
When a fopen() is done on a file that has permissions that are set to
not allow the current process user to read it or the file doesn't exist
it returns false. This is expected. The problem is when feof() is fed
the invalid handle it doesn't return TRUE() thus creating an infinite
loop in the following code example.
Reproduce code:
---------------
<?php
$fp = fopen( 't.txt', 'r' );
while( !feof( $fp ) )
{
print fgets( $fp );
}
fclose( $fp );
?>
Expected result:
----------------
feof() would return TRUE to cancel the loop and the script would end.
There would of course be warnings because of the invalid file handle,
but that is expected.
There should be better error handling on the developers part and catch
the invalid file handle, but I would expect the file functions to
handle this situation accordingly.
Actual result:
--------------
Inifinite loop
