"b" is always assumed, unless "t" is explicitly given.

I just checked and I can't get the code to work even if I manually specify the
open mode.

While Windows PHP version displays the notice as it should:

$ php -d "error_reporting=-1" -d "display_errors=stderr" -r '(new SplFileObject("test.txt"))->fwrite("test");'
PHP Notice:  SplFileObject::fwrite(): write of 4 bytes failed with errno=9 Bad file descriptor in Command line code on line 1
