Twig Domain parser extension

This package provides Twig extensions for PHP Domain parser v5.4+

System Requirements

You need:

PHP >= 7.1.0 but the latest stable version of PHP is recommended

Installation

$ composer require bakame/twig-domain-parser-extension

Setup

use Bakame\Twig\Pdp\Extension;
use Pdp\Cache;
use Pdp\CurlHttpClient;
use Pdp\Manager;

$manager = new Manager(new Cache(), new CurlHttpClient(), '1 DAY');
$rules = $manager->getRules();
$topLevelDomains = $manager->getTLDs();

$twig->addExtension(new Extension($rules, $topLevelDomains));

Because the Pdp\Cache class implements PSR-16, you can use any PSR-16 compatible cache driver. For instance you can use the Symfony cache component instead:

$ composer require symfony/cache

use Bakame\Twig\Pdp\Extension;
use Pdp\CurlHttpClient;
use Pdp\Manager;
use Symfony\Component\Cache\Simple\PDOCache;

$dbh = new PDO('mysql:dbname=testdb;host=127.0.0.1', 'dbuser', 'dbpass');
$cache = new PDOCache($dbh, 'psl', 86400);
$manager = new Manager($cache, new CurlHttpClient(), 86400);

$twig->addExtension(Extension::createFromManager($manager));

You can directly get an Extension instance from a Pdp\Manager object using the createFromManager named constructor.

Usage

Manipulating a Domain object in Twig template

{% set host = 'www.食狮.公司.cn' %}
hostname: {{ resolve_domain(host) }} {#  www.食狮.公司.cn #}
subDomain : {{ resolve_domain(host).subDomain }} {#  www #}
registrableDomain : {{ resolve_domain(host).registrableDomain }} {#  食狮.公司.cn #}
publicSuffix : {{ resolve_domain(host).publicSuffix }} {#  公司.cn #}
isICANN : {{ resolve_domain(host).ICANN ? 'ok' : 'ko' }} {#  ok #}
isPrivate : {{ resolve_domain(host).private ? 'ok' : 'ko' }} {# ko #}
isKnown : {{ resolve_domain(host).known ? 'ok' : 'ko' }} {#  ok #}
ascii : {{ resolve_domain(host).toAscii }} {#  www.xn--85x722f.xn--55qx5d.cn #}
unicode : {{ resolve_domain(host).toUnicode }} {#  www.食狮.公司.cn #}
label : {{ resolve_domain(host).label(0) }} {# cn #}
publicSuffix : {{ resolve_domain('foo.github.io', constant('Pdp\\Rules::PRIVATE_DOMAINS')).publicSuffix }} {# github.io #}

The resolve_domain function returns a Pdp\Domain object you can use to manipulate to returns various informations about your hostname. The returned object is resolved againts the PSL resources using Pdp\Rules::resolve method. This means that you can optionnally decide which section the domain should be resolve too.

The resolve_domain parameters are:

$host a scalar or a stringable object
$section : a string representing one of the PSL section
- Rules::ICANN_DOMAINS : to resolve the domain against the PSL ICANN section
- Rules::PRIVATE_DOMAINS : to resolve the domain against the PSL private section

By default the resolution is made against the section with the longest public suffix.

Detecting if the host contains a IANA top level domain

hostname: {{ host is topLevelDomain ? 'ok' : 'ko' }} {# ok #}

The topLevelDomain tests tells whether the submitted domain contains a known IANA top level domain
