Note: this still occurs in 4.0.6 (I think they're the same bug)
What I did: tried to read over a file backwards using fseek().
What should have happened: I should be able to create an array of the last few lines of a file, without reading the whole file.
What did happen: for every newline fseek()ed over fread() seemed to gain a byte.
I believe this could be a problem with the way fseek() handles new lines in Win32 (possibly not always). fread() seems to read Win32 newlines as one byte, while fseek() reads them as two.
In the following example, if the file has no newlines or the newlines are in Unix format, $buf is identical. If there are Win32 newlines, it isn't.
<example>
$fp = fopen('/temp/newline.txt', 'r');
fread($fp, 5);
$buf = fread($fp, 5);
fclose($fp);
$fp = fopen('/temp/newline.txt', 'r');
fseek($fp, 5);
$buf = fread($fp, 5);
fclose($fp);
</example>
