fgets() gets to read past EOF, but it shouldn't. looks like feof() is
broken.

cynic - can you try HEAD or a snapshot from the last day or so?
I fixed an eof related issue recently.

I get bool(true) with 4.2.3 and 4.3.0-dev (from yesterday), both
mod_php, Linux 2.4.19.
Maybe it's a documentation problem:
the manual only says about the return value of fgets():
If an error occurs, returns FALSE.
Nothing is said about the return value on EOF (only "People used to the
'C' semantics of fgets() should note the difference in how EOF is
returned."), so I guess fgets() is free to return whatever it likes on
EOF. Was this different in previous versions of PHP?

am I the only one who thinks that this should not output anything?
<?php
$fd = fopen(__FILE__, 'r');
while (!feof($fd)) fgets($fd, 4096) || var_dump(feof($fd));
fclose($fd);
I get bool(false) from 4.4.0-dev (cli) and 4.2.2 mod_php.
