A PHP Class used to check if a domain has been registered.
Created to be fast and easy to use, modify and redistribute as you wish, credit me if appropriate.
composer create-project -s dev cwd/domain-availability
- Download the AvailabilityService.php file and place it "somewhere" in your project folder.
- Include it in your PHP file.
- Done.
<?php
require('vendor/autoload.php');
$service = new HelgeSverre\DomainAvailability\AvailabilityService(true);
$available = $service->isAvailable("helgesverre.com");
if ($available) {
echo $domain." is not registered\n";
} else {
echo $domain." is registered\n";
}or look at example.php for an example.
The WHOIS server array is incomplete and some data is missing, the most popular TLD's are working though, I will update these as I can, I suggest making your own array of whois server information so you know which TLD is available, for a full list of TLD's and WHOIS servers please go to the IANA website
These are the domain extensions that are supported by this script.
