use Doctrine\Common\Collections\Collection;

public function sort(Collection $objects, $name, $property = null)
{
    $values = $objects->getValues();
    usort($values, function ($a, $b) use ($name, $property) {
        $name = 'get' . $name;
        if ($property) {
            $property = 'get' . $property;
            return strcasecmp($a->$name()->$property(), $b->$name()->$property());
        } else {
            return strcasecmp($a->$name(), $b->$name());
        }
    });
    return $values;
}

I would like to avoid this hack though and still would like to know a real solution
