A PHP library used to check domain name availability.
This is not a reliable way to check for domain availability on a large or even a medium scale, this will not handle your "webhosting business" or anything that requires a high level of data accuracy, if you need something like that, please use WhoAPI or Namecheap's API.
And no, I did not build nor do i support the WordPress plugin that is being sold on CodeCanyon which uses this package under the hood.
$ composer require --dev helgesverre/domain-availabilityor
{
"require": {
"helgesverre/domain-availability": "~1.5.0"
}
}
<?php
require './vendor/autoload.php';
use Helge\Loader\JsonLoader;
use Helge\Client\SimpleWhoisClient;
use Helge\Service\DomainAvailability;
$whoisClient = new SimpleWhoisClient();
$dataLoader = new JsonLoader("path/to/servers.json");
$service = new DomainAvailability($whoisClient, $dataLoader);
if ($service->isAvailable("helgesverre.com")) {
echo "Domain is available";
} else {
echo "Domain is already taken!";
}
or look at example.php for a more real world example.
The WHOIS server list is incomplete and some data is missing. The most popular TLDs are working, though, and I will update these as I can. I suggest making your own list of whois servers and their "not found"-responses so you know which TLD is available. For a full list of TLDs and WHOIS servers please go to the IANA website.
To check what they return when a domain is not found, you simply have to manually query the servers and check.
These are the domain extensions that are supported by this script.

Due to the fact that a lot of the domain extensions listed on the IANA website do not contain any information on which WHOIS server to use when querying for the domain information, the following domain extensions are not available (yet):
.dj, .do, .eg, .eh, .er, .et, .fj, .fk, .fm, .gallery, .gb, .ge, .gf, .gh, .gm, .gn, .gp,
.gr, .gt, .gu, .gw, .hm, .jetzt, .jm, .jo, .kh, .km, .kn, .kp, .kred, .kw, .ky, .lb,

If you know the whois server for any of these please feel free to create an issue with an update.

If you are getting the error:
Fatal error: Call to undefined function Pdp\idn_to_ascii()
Be sure to enable the php extension called intl as the domain parsing extension requires it!
If certain domain extensions are always or very often returning an unexpected value, please create an issue instead of emailing me in broken english. In your issue provide me with the following:
- Your webhost
- Link to your website where the error is happening
- The extension and domain you are trying to check availability for
Keep in mind that this library queries the WHOIS servers directly and if you "spam" them with requests, you will get temporary banned and that will cause the library to say the domain always is taken.
