A wildcard event handler that logs all Yii/Craft events

EventCatcher.php

class EventCatcher
{

    /**
     * @var array 
     */
    protected $classConstants = [];

    public function __invoke(yii\base\Event $event)
    {
        $triggerClass = get_class($event->sender);
        $eventClass   = get_class($event);
        $name         = $this->getEventConstantName($triggerClass, $event->name);
        \Craft::warning("$triggerClass::$name using ($eventClass)", 'event');
    }

    protected function getEventConstantName(string $class, string $name): string
    {

        if (!isset($this->classConstants[$class])) {
            $info                         = new ReflectionClass($class);
            $this->classConstants[$class] = $info->getConstants();
        }

        foreach ($this->classConstants[$class] as $k => $v) {
            if ($v === $name) {
                return $k;
            }
        }

        return $name;
    }
}

This is fantastic Oliver, and great use of the __invoke() method!!
