基础使用
----

[](#基础使用)

### 1. 创建容器实例

[](#1-创建容器实例)

```
use FastD\Container\Container;

$container = new Container();
```

### 2. 注册服务

[](#2-注册服务)

```
// 注册类服务
$container->add('logger', Monolog\Logger::class);

// 注册闭包服务
$container->add('database', function() {
    return new PDO('sqlite::memory:');
});

// 注册配置数组
$container->add('config', [
    'app_name' => 'My Application',
    'debug' => true
]);
```

### 3. 获取服务实例

[](#3-获取服务实例)

```
// 获取服务实例 (PSR-11 标准方法)
$logger = $container->get('logger');
$config = $container->get('config');

// 检查服务是否存在
if ($container->has('logger')) {
    $logger = $container->get('logger');
}
```

### 4. 数组访问支持

[](#4-数组访问支持)

```
// 使用数组语法操作容器
$container['cache'] = RedisCache::class;

if (isset($container['cache'])) {
    $cache = $container['cache'];
}

unset($container['cache']);
```

更多使用示例请参考 [完整文档](./docs/installation.md)。
