Bug description: fseek() offset problem with Win32 newlines
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>
