League\Event is a PHP library for adding event-driven behavior to applications and domain models. It provides event dispatching, listeners, and emitter abstractions as part of The League of Extraordinary Packages.

Use cases

• dispatch domain events in a PHP application
• decouple components with an event emitter
• register listeners for application events
• implement observer pattern in PHP
• trigger side effects when domain actions occur
• build event-driven architecture in PHP

When to choose

• you need a lightweight, well-maintained event dispatcher for PHP
• you want PSR-friendly domain event handling without a full framework
• you prefer small composable League packages

When to avoid

• you need asynchronous or queued event processing
• your framework already ships a full-featured event system you're happy with
• you need message-broker-backed pub/sub across services
