Remove domain extension

Question

So let\'s say I have just-a.domain.com,just-a-domain.info,just.a-domain.net how can I remove the extension .com,.net.info ... and I need the result

Answer 1

  preg_match('/(.*?)((?:\.co)?.[a-z]{2,4})$/i', $domain, $matches);

$matches[1] will have the domain and $matches[2] will have the extension

Will produce the output
