#``attribute`` > Twig 1.2 加入了 ``attribute``函數。 使用 ``attribute``函數，可以訪問變量的“動態”屬性： {{ attribute(object, method) }} {{ attribute(object, method, arguments) }} {{ attribute(array, item) }} In addition, the ``defined`` test can check for the existence of a dynamic attribute: {{ attribute(object, method) is defined ? 'Method exists' : 'Method does not exist' }} 注意： > The resolution algorithm is the same as the one used for the ``.``notation, except that the item can be any valid expression.
