how to use preg_match

[Anon]

I want to use preg_match to match the string which string may contain letters, hyphens, apostrophes, whitespace, and umlauts and accents. But they may not start with anything else but letters, umlauts and accents, like -day, 'n .

preg_match("(/[a-zA-Z{umlauts_and_accents_list}][-' a-zA-Z{umlauts_and_accents_list}]*)/",$subject,$result);
