    The MongoDB\Driver\Monitoring\CommandSubscriber interface

    (mongodb >=1.3.0)

    Classes may implement this interface to register an event subscriber that is notified for each started, successful, and failed command event. See Application Performance Monitoring (APM) for additional information.

    class MongoDB\Driver\Monitoring\CommandSubscriber implements MongoDB\Driver\Monitoring\Subscriber {
    /* 方法 */
    abstract public function commandFailed(MongoDB\Driver\Monitoring\CommandFailedEvent $event): void
    abstract public function commandStarted(MongoDB\Driver\Monitoring\CommandStartedEvent $event): void
    abstract public function commandSucceeded(MongoDB\Driver\Monitoring\CommandSucceededEvent $event): void
    }
    版本 说明
    PECL mongodb 2.0.0 之前声明为暂定的返回类型现在已被强制执行。
    PECL mongodb 1.15.0 在 PHP 8.0 及更高版本中，方法的返回类型被声明为暂定（tentative）， 这会导致在实现该接口但未声明相应返回类型的代码中触发弃用提示。 可以添加 #[ReturnTypeWillChange] 属性来消除该弃用提示。
