[PHP] TLD List, Inc. Level 2 & 3

beaver6813 · 06-06-2010, 09:56 AM

Whilst working on a new open-source project I needed to be able to be able to detect/remove the TLD’s from hostnames. This is no easy task algorithmically as example.co.uk (level 2) is just as valid as example.com (level 1) which is also just as valid as example.bob.shiga.jp (level 3), distinguising between what a sub-domain is and a domain that just has a really long ending is difficult.

Long story short I've created a quick script that will process the list from Mozilla into a serialized PHP accessible format. You could then use this list array to check for matches in a domain name for example.

PHP Code:

  <?php
//TLD List Updater (Formats to Serialized PHP)
//Created by Beaver6813 (Beaver6813.com). Big thanks to the Mozilla community!
$tldlist = file("http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/effective_tld_names.dat?raw=1");
$toplist = array();
????: NamePros.com http://www.namepros.com/code/660180-php-tld-list-inc-level-2-a.html
foreach($tldlist as $key=>$value)
    {
    $value = trim($value);
    if(substr_count($value,"//")==0&&!empty($value))
????: NamePros.com http://www.namepros.com/showthread.php?t=660180
        {
        if(substr_count($value,".")==0)
            $sublist[$value] = array();
        else
            {
            $dotxplode = explode(".",$value);
            $dotxplode = array_reverse($dotxplode);
            $sublist[$dotxplode[0]][] = $value;
            }
        }
    }
file_put_contents("effective_tld_sublist.dat",serialize($sublist));
?>

NOTE: I'll be including a full lookup function when I've created and tested it

I've put a fuller explanation of how to use the list on my blog at [PHP] TLD List, Inc. Level 2 & 3*/* Beaver6813.com

If it helps you, Rep appreciated!
