Summary: feof not reporting end of file when using fread

New Comment:
feof() indicates that you have tried to read beyond the end of the file. For a
3-
byte file, if you only read 3 bytes you have not yet tried to read beyond the
end
of the file and thus feof() has not triggered yet. feof() cannot predict that
the
next read will fail. By the time you do the next read perhaps the file has
grown.
This is exactly how this function works in C as well which is where it comes
from.

If using fread and have read the last byte in the file, feof still reports have
not reached end of file.

<?php
$fp = fopen('feof.bin', 'w');
fwrite($fp, 'abc');
fclose($fp);
$fp = fopen('feof.bin', 'r');
$bytes = fread($fp, 3);
echo feof($fp) ? 't' : 'f';
echo PHP_EOL;
fclose($fp);
unlink('feof.bin');
Expected result:
----------------
Expected feof to return true
Actual result:
--------------
feof returned false.
