Re: eregi and emails

(eregi("^[_\.0-9a-z-]+@([0-9a-z][-0-9a-z\.]+)\.([a-z]{2,3}$)",$email, $check)) In the above -> you're searching for a '\', '_', '.', '-' or an alphanum entry, which should occur atleast one or more times, followed by @, followed by an alphanum entry followed by another alphanum or a slash or a dot, followed by a '.' then by minimum 2 or 3 minimum letters, at the end. Now in the above the following would be valid : \._@m\3..com -> do u want this ? not exactly! eregi("(^[a-z0-9]+)([_.-]([a-z0-9])+)*[@]([a-z0-9]+) ([._-]([a-z0-9]+))*[.]([a-z0-9]){2}([a-z0-9])?$ try the above.... alphanum followed 0 or more dots which necessarily (if a . is there) have to be followed by a letter or number (eg: mukul.18), this can be done unlimited no. of times (eg: mukul.net.18.hello) followed by @ followed by an alphanum then by 0 or more dots which again necessarily have to be followed by a letter or number, again which can go unlimited times : @gh.ghg.gkjd.12 the only problem now here is that a guy can enter mukul@domain.12 ... and the last part is what defines the above that if there is a subdomainal address then an ext. is necessary. hope this clears it up. Thanks to Lars Torben Wilson and Maxim Maletsky who cleared by RegExp fundas. thanks. ===== To Find Out More About Me : http://mukul.tsx.org/ __________________________________________________ Do You Yahoo!?
