Doma(in)Validity PHP package
============================

[](#domainvalidity-php-package)

Light PHP package to validate domains using the Mozilla [Public Suffix List](https://publicsuffix.org/).

[Doma(in)Validity](https://api.domainvalidity.dev/) was born because the usual "validate a domain" regex grows new edge cases every time you look away — multi-level TLDs (`co.uk`, `com.mx`), IDN labels, private suffixes (`*.amazonaws.com`). This package outsources the hard part to the PSL.

Requirements
------------

[](#requirements)

- PHP **>= 8.2.0** (for v3.x)
- PHP **>= 8.1.0** (for v2.x)

Installation
------------

[](#installation)

```
composer require domainvalidity/php-domain-validator
```

Quick start
-----------

[](#quick-start)

```
use DomainValidity\Factory;

$psl       = file_get_contents('path/to/public_suffix_list.dat');
$validator = Factory::make($psl);

$host = $validator->validate('www.domainvalidity.dev');

$host->isValid();   // true
$host->tld();       // 'dev'
$host->domain();    // 'domainvalidity.dev'
$host->toString();  // 'www.domainvalidity.dev'
```

> Cache the Public Suffix List and refresh at most once per day. It is updated only a few times per week, so more frequent fetching is wasteful. See the usage guide below for a secure, cached fetch pattern.
