Type-safe access to array configurations.

Wrap a config array (or pull one from a PSR-11 container) and read values with typed accessors that throw on a missing key or a wrong type — so a typo or a misconfigured value fails loudly instead of silently returning null.

Installation

composer require kaiseki/wp-config

Requires PHP 8.2 or newer.

Usage

use Kaiseki\WordPress\Config\NestedArrayConfig;

$config = new NestedArrayConfig([
    'db' => [
        'host' => 'localhost',
        'port' => 3306,
    ],
]);

$config->string('db/host'); // "localhost"
$config->int('db/port');    // 3306
$config->has('db/user');    // false

Paths are slash-separated. The typed getters (string(), int(), float(), bool(), array()) throw UnknownKeyException if the path is missing and InvalidValueException if the value is not of the expected type. has() reports whether a path resolves.

From a PSR-11 container

Config::get() resolves the ConfigInterface service from a container:

use Kaiseki\WordPress\Config\Config;

$config = Config::get($container); // expects ConfigInterface::class in the container

ConfigProvider wires that up for laminas-style config aggregators: it aliases ConfigInterface to NestedArrayConfig and registers a factory that builds the config from the container's config entry.

Config::initClassMap() resolves a map of keys to class instances from the container:

$map = Config::initClassMap($container, ['logger' => LoggerInterface::class]);
// ['logger' => <instance from container>]
