That's because you have an unescaped / within your regex, so it sees
/^M?(([0-9]?)[ ]?([0-9])(/ followed by a ? as a regex modifier.

Try this:

} elseif (preg_match('/^M?(([0-9]?)[ ]?([0-9])(\/?)([0-9]*))SM$/',

It wasn't a problem in ereg() because the regex didn't need to be enclosed in //

Cheers
