Ellipsis before parameter variable PHP Laravel - development

Ellipsis before parameter variable PHP Laravel

Was going through Laravel Illuminate core when I met this code..What’s does the ellipsis before parameter $guards mean?

public function handle($request,Closure $next,...$guards){
    $this->authenticate($guards);
    return $next($request);
}
