Actually the file has two lines, because you're having a line break (NL,
CR or CRLF) after the word "one", I assume. Either remove this line
break, or set appropriate flags for $file:

$file->setFlags(
SplFileObject::READ_AHEAD | SplFileObject::SKIP_EMPTY
);

See <http://www.php.net/manual/en/splfileobject.setflags.php>.
