访问Drupal中另一个对象内的对象

Question

我有一个像drupal这样的数组输出，如何从中访问[name]的值 field_episode_tags，到目前为止我有这个

print $node->field_episode_tags['und']['0']['taxonomy_term']->['name']

当我达到'分类学术语'时，我尝试使用另一个对象 - ＆gt; poitner但是没有用。

您需要直接访问实例datamember而不使用方括号[]。这些用于数组键。

 print $node->field_episode_tags[LANGUAGE_NONE]['0']['taxonomy_term']->name
