Way too complicated and using the old deprecated ereg* functions.

If the PW should only contain letters and digits, then use a pattern
that matches for exactly that:

preg_match('#[A-Z\d]+#i', $str);

If there has to be a capital letter somewhere in the PW, then try a
combination like this:

preg_match('#[a-zA-Z\d]*[A-Z][a-zA-Z\d]*#', $str);
