Getting domain name without TLD

Question

I have this code right here:

    // get host name from URL
    preg_match(\'@^(?:http://)?([^/]+)@i\',
    \"http://www.joomla.subdomain.php.net/index.html\"         


        

Answer 1

It's really easy:

function get_tld($domain) {
    $domain=str_replace("http://","",$domain); //remove http://
    $domain=str_replace("www","",$domain); //remowe www
    $nd=explode(".",$domain);
    $domain_name=$nd[0];
    $tld=str_replace($domain_name.".","",$domain);
    return $tld;
}

To get the domain name, simply return $domain_name, it works only with top level domain. In the case of subdomains you will get the subdomain name.
