# Événement
Événement is a very simple event dispatching library for PHP.
It has the same design goals as [Silex](http://silex-project.org) and
[Pimple](http://pimple-project.org), to empower the user while staying concise
and simple.
It is very strongly inspired by the EventEmitter API found in
[node.js](http://nodejs.org).

## Fetch
The recommended way to install Événement is [through composer](http://getcomposer.org).
Just create a composer.json file for your project:
```JSON
{
"require": {
"evenement/evenement": "^3.0 || ^2.0"
}
}
```
**Note:** The `3.x` version of Événement requires PHP 7 and the `2.x` version requires PHP 5.4. If you are
using PHP 5.3, please use the `1.x` version:
```JSON
{
"require": {
"evenement/evenement": "^1.0"
}
}
```
And run these two commands to install it:
$ curl -s http://getcomposer.org/installer | php
$ php composer.phar install
Now you can add the autoloader, and you will have access to the library:
```php
<?php
require 'vendor/autoload.php';
```
## Usage
### Creating an Emitter
```php
<?php
$emitter = new Evenement\EventEmitter();
```
### Adding Listeners
```php
<?php
$emitter->on('user.created', function (User $user) use ($logger) {
$logger->log(sprintf("User '%s' was created.", $user->getLogin()));
});
```
### Emitting Events
```php
<?php
$emitter->emit('user.created', [$user]);
```
