Événement
Événement is a very simple event dispatching library for PHP.
It has the same design goals as Silex and
Pimple, to empower the user while staying concise
and simple.
It is very strongly inspired by the EventEmitter API found in
node.js.
Fetch
The recommended way to install Événement is through composer.
Just create a composer.json file for your project:
{
"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:
{
"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
require 'vendor/autoload.php';

$emitter = new Evenement\EventEmitter();

$logger->log(sprintf("User '%s' was created.", $user->getLogin()));
});
