Top Level Domain (TLD) validation library for PHP

This package allows validation of top level domains against the official The DNS Root Zone database from iana.org.
Use this to validate e.g. domains or email addresses.

The DNS Root Zone is the upper-most part of the DNS hierarchy, and involves delegating administrative responsibility of “top-level domains”, which are the last segment of a domain name, such as .com, .uk and .nz.

The database is stored locally and automatically updated for new database versions.

Installation

Install this package via composer:

composer require arubacao/tld-checker

Laravel

If you would like to use arubacao/tld-checker with the Laravel Validator, you must also register the service provider:
(only required for Laravel <=5.4, for Laravel >=5.5 auto-discovery is enabled.)

// config/app.php

'providers' => [
    // Other Service Providers
    Arubacao\TldChecker\TldCheckerServiceProvider::class,
],

Notes:

• arubacao/tld-checker is functional and fully tested for PHP 7.0 - 8.0 & Laravel 5.0 - 8.x.

Usage

Check a TLD using Validator::isTld():

use Arubacao\TldChecker\Validator;

Validator::isTld('com');        // true
Validator::isTld('CN');         // true (case insensitiv)
Validator::isTld('москва');     // true (works with internationalized domain name (IDN) | unicode)
Validator::isTld('XN--CZRS0T'); // true (works with encoded IDN | 商店)
Validator::isTld('.org');       // true (allows dot prefix)
Validator::isTld('apricot');    // false

Check if a string ends with a valid TLD using Validator::endsWithTld():

use Arubacao\TldChecker\Validator;

Validator::endsWithTld('apple.com');                            // true
Validator::endsWithTld('NEWS.CN');                              // true (case insensitiv)
Validator::endsWithTld('müller.vermögensberater');              // true (works with internationalized domain name (IDN) | unicode)
Validator::endsWithTld('xn--mller-kva.xn--vermgensberater-ctb');// true (works with encoded IDN | müller.vermögensberater)
Validator::endsWithTld('farming.apricot');                      // false

This package extends the Laravel Validator with these 2 methods:

• is_tld
• ends_with_tld

Use them as follows:

$request->validate([
    'tld' => 'required|is_tld',
    'email' => 'required|ends_with_tld'
]);

Testing

composer test
