This library provides PHP utilities functions to manage URLs. Read PHP DOC

Install

Install package with composer

composer require hugsbrugs/php-http

In your PHP code, load librairy

require_once __DIR__ . '/../vendor/autoload.php';
use Hug\Http\Http as Http;

Configuration

In order to use cache mechanism, define following constants

define('PDP_PDO_DSN', 'mysql:host=localhost;dbname=database');
define('PDP_PDO_USER', 'username');
define('PDP_PDO_PASS', 'password');
define('PDP_PDO_OPTIONS', [PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION]);

Alternatively define path to the local stored public suffix list

define('PUBLIC_SUFFIX_LIST', realpath(__DIR__ . '/../../../cache/public_suffix_list.dat'));

This method should not be used in production since it's really slow.

Otherwise the default, not accurate, cache/public_suffix_list.dat file will be used.
