Yeah, after reading merek's response I realized I missed what
exactly your problem is.

Thats odd, I come up with a 'Bad' echo also. The only thing I can
think of is there is some sort of implicit casting happening to the
$value within the comparison. But it does seem very strange that
XP would cast but *nix doesn't

In that case test the condition reversed:
  if ($value != $number)

I'm at a loss as to why it doesn't work on your system.
