README

Package supplies support of event handling on different kind of objects. To use this you just inherite your class from Phasty\Events\Eventable or use Phasty\Events\EventableTrait trait within you class:

class SomeCoolClass extends Phasty\Events\Eventable {
} 

$obj = new SomeCoolClass;
$obj->on("hello-event", function($event) {
    echo $event->getData();
});
$obj->trigger("hello-event", "Hello world");

Output:

Hellow world!

And more:

class Button extends Phasty\Events\Eventable {
    public function __construct() {
        $this->on("click", "sayHello");
        $this->on("click", "sayGoodbye");
    }
    protected function sayHello() {
        echo "Hello!\n";
    }
    protected function sayGoodbye() {
        echo "Bye!\n";
    }
    public function click() {
        $this->trigger("before-click");
        $this->trigger("click");
    }
}

$btn = new Button;
$btn->on("before-click", function () {
    echo "Before click handler\n";
});
$btn->click();
$btn->off("click", "sayHello");
$btn->click();

Output:

Before click handler
Hello!
Bye!
Before click handler
Bye!
