📖 Full Documentation | 🐛 Report Issues

✨ Features

• PSR-11 Compatible — Implements ContainerInterface
• Auto-wiring — Automatic constructor injection
• Singletons — Shared instances across resolves
• Factories — New instances per resolution
• Tagged Services — Group related services
• Contextual Binding — Different implementations per consumer

📋 Requirements

🚀 Installation

composer require wpdiggerstudio/wpzylos-container

📖 Quick Start

use WPZylos\Framework\Container\Container;

$container = new Container();

// Bind a singleton (shared instance)
$container->singleton(DatabaseConnection::class, fn() => new DatabaseConnection());

// Bind a factory (new instance each time)
$container->bind(Logger::class, fn() => new Logger());

// Auto-wiring (automatic dependency resolution)
$container->bind(UserService::class);

// Resolve
$db = $container->get(DatabaseConnection::class);
$logger = $container->get(Logger::class);
$userService = $container->get(UserService::class);

🏗️ Core Features

Singleton Binding

// Registered once, shared everywhere
$container->singleton(Config::class, fn() => new Config('config.php'));

$config1 = $container->get(Config::class);
$config2 = $container->get(Config::class);
// $config1 === $config2

Factory Binding

// New instance every time
$container->bind(Request::class, fn() => new Request());

$req1 = $container->get(Request::class);
$req2 = $container->get(Request::class);
// $req1 !== $req2

Auto-wiring

class UserService {
    public function __construct(
        private DatabaseConnection $db,
        private Logger $logger
    ) {}
}

// Container automatically resolves dependencies
$container->bind(UserService::class);
$userService = $container->get(UserService::class);

Interface Binding

$container->bind(CacheInterface::class, RedisCache::class);
$container->singleton(LoggerInterface::class, FileLogger::class);

Tagged Services

$container->tag([EmailNotifier::class, SlackNotifier::class], 'notifiers');

$notifiers = $container->tagged('notifiers');
foreach ($notifiers as $notifier) {
    $notifier->send($message);
}
