Data from your service reads from the line written in the code stiffly, that is if the place of the projection of passwords changes , search engine will not work then :-( I have to apply such method only at you because cyrlica enough disturbs in scanning ;-)

$ LOGINURL ='http:// md5.xek.cc';
$ POSTFIELDS = 'hash ='.$ hash.'& act = find';

+ curl & trim , strip_tags etc
