.co.uk
.com.au
etc
Here’s my version: (gets the current domain extension)

$temparray=explode(‘.’,trim($_SERVER['HTTP_HOST'],”www.”));
$domain=array_shift($temparray);
$domainExt=join(‘.’,$temparray);

Coz looking at your initial solution, it would not work in every situation coz if there was no dot (.) in the $domain variable, then strrpos would return false, then you would effectively be making this call: $extension = substr($domain, FALSE+1); //false in lowercase if you like. Perhaps that could translate to substr($domain,1), which would output everything from the 2nd character of $domain going forward. So I'm glad you ended up using explode() instead. That's why it's part of PHP. ...A mouthful by Tashman :) Yes, I too would have used explode, too.
