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'); 
} 

或写斜线你FQCN：

use Symfony\Component\Intl\ResourceBundle\CurrencyBundle; 

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

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