What are you trying to do exactly, maybe there's a better way. If you're trying to determine if an email address is valid there's a pretty cool way to do so by using dns records. It's like 5 lines, here's the site http://www.sitepoint.com/article/users-email-address-php As far as actually just getting the domain, w/o subdomains from a string you could try this. I'm not sure if the code runs because I haven't tested it, and I have been working exclusively with Delphi for a month so something might be off. function getDomain($email) { list($userName, $mailDomain) = split("@", $email); $anarray = split(".", $mailDomain); for ($i = 0; $i < count($anarray); $i++) { if (in_array($anarray[$i], $TLDArray)) // if $anarray[$i] is a TDL then we move back 1 to get it's domain

       return $anarray[$i-1] . '.' . $anarray[$i];

} }

As far as I can tell, this doesn't work at all. Yours, http://www.cmsws.com/examples/php/domain_verification/example2.php Mine, http://www.cmsws.com/examples/php/domain_verification/example.php

And yours is fatally flawed. Not all ccTLDs are sub-divided.

ok, too quick on the draw there. one would have to be able to run a whois look up on the output to see if it fails or succeeds to be able to get the final verdict, but it would get you most of the way there. :)
