Answer 1

你应该写use声明：

use Symfony\Component\Intl\ResourceBundle\CurrencyBundle;
use Symfony\Component\Intl\Intl;

class EventDetailController extends Controller
{
    $currency = $data[0]['currency'];
    $Currency= USD

    Intl::getCurrencyBundle()->getCurrencySymbol('USD'); 
}

或使用前导斜杠编写您的 FQCN：

use Symfony\Component\Intl\ResourceBundle\CurrencyBundle;

class EventDetailController extends Controller
{
    $currency = $data[0]['currency'];
    $Currency= USD

    \Symfony\Component\Intl\Intl::getCurrencyBundle()->getCurrencySymbol('USD'); 
}
