this 1 should work. there might faults it, none can think of right now. if want improve on it, feel free so.

/http:\/\/(?:www\.)?([a-z0-9\-]+)(?:\.[a-z\.]+[\/]?).*/i  http:\/\/            matches "http://" part (?:www\.)?           non-capturing group matches 0 or 1 "www." ([a-z0-9\-]+)        capturing group matches character ranges a-z, 0-9                      in addition hyphen. wanted extract. (?:\.[a-z\.]+[\/]?)  non-capturing group matches tld part (i.e. ".com",                      ".co.uk", etc) in addition 0 or 1 "/" .*                   matches rest of url
