InitPHP EventEmitter
====================

[](#initphp-eventemitter)

> ## ⚠️ DEPRECATED — Use [`initphp/events`](https://github.com/InitPHP/Events) instead
>
> [](#️-deprecated--use-initphpevents-instead)
>
> As part of the InitPHP package consolidation, **this package has been merged into [`initphp/events`](https://github.com/InitPHP/Events) starting with version 2.0.** The new package bundles the same `EventEmitter` primitive plus the higher-level `Events` / `Event` facade.
>
> This repository is kept read-only for historical reference. The final release (`1.0.1`) ships a bug fix for `EventEmitter::emit()` (see below) but **no further updates will be released**.
>
> ### Migration
>
> [](#migration)
>
> 1. Update your `composer.json`:
>
>     ```
>     - "initphp/event-emitter": "^1.0",
>     + "initphp/events": "^2.0"
>     ```
> 2. Your existing imports keep working: `initphp/events:^2.0` ships a `class_alias` so `\InitPHP\EventEmitter\EventEmitter` and `\InitPHP\EventEmitter\EventEmitterInterface` remain resolvable.
> 3. When you next touch the code, prefer the canonical namespace:
>
>     ```
>     // Before
>     use InitPHP\EventEmitter\EventEmitter;
>
>     // After
>     use InitPHP\Events\EventEmitter;
>     ```
>
> Composer declares a `replace` from `initphp/events:^2.0` to `initphp/event-emitter`, so the two packages will not be installed side-by-side.
>
> ### `emit()` bug fix in 1.0.1
>
> [](#emit-bug-fix-in-101)
>
> Version `1.0.1` of this package contains a single bug fix in `EventEmitter::emit()`: the inner loop now correctly passes each individual `$listener` to `call_user_func_array`, instead of the surrounding `$listeners` array. Before this fix, emitted events fired no listeners.
