Check availability of domain names and get WHOIS information.

• Check availability of domains
• Retrieve WHOIS information of domains
• Support for over 350 TLDs, including new generic TLDs like .coffee or .sexy
• Command line tool and library
• Compatible with PHP >= 5.4 and HHVM

Dependending on how you want to use Domain there exist different installation methods.

If you want to use the library as a dependency in your project you should use Composer to do so:

$ composer require cocur/domain:@dev

Currently there exists no stable release of domain.

If you only want to use the command line tool to retrieve WHOIS information you can download the PHAR.

$ wget https://github.com/cocur/domain/releases/download/v0.1/whois.phar
$ chmod +x whois.phar
$ mv whois.phar /usr/local/bin/cwhois

You can now retrieve WHOIS information using Cocur Domain by executing

$ cwhois

You can use the included command line tool to retrieve WHOIS information about a domain:

$ php whois.phar cocur.co

The library contains two main classes: Whois\Client and Availability\Client They require information about WHOIS servers and patterns to match available domains stored in data/tld.json.

use Cocur\Domain\Connection\ConnectionFactory;
use Cocur\Domain\Data\DataLoader;
use Cocur\Domain\Whois\Client;

$factory = new ConnectionFactory();
$dataLoader = new DataLoader();
$data = $dataLoader->load(__DIR__.'/data/tld.json');

$client = new Client($factory, $data);

echo $client->query($domainName);

To check the availability of a domain name the Availability\Client requires an instance of Whois\Client.

use Cocur\Domain\Connection\ConnectionFactory;
use Cocur\Domain\Data\DataLoader;
use Cocur\Domain\Whois\Client as WhoisClient;
use Cocur\Domain\Availability\Client as AvailabilityClient;

$factory = new ConnectionFactory();
$dataLoader = new DataLoader();
$data = $dataLoader->load(__DIR__.'/data/tld.json');

$whoisClient = new WhoisClient($factory, $data);
$client = new AvailabilityClient($whoisClient, $data);

echo $client->isAvailable($domainName);
