来自 stdClass 对象的引用字段，其中包含可绘制信息的数组

Question

我想 return 从以下包含嵌套数组和 stdClass 对象的大量混合数据数组中获取 Birthday 字段的值。我尝试了以下代码，但没有成功，如果有任何帮助，我将不胜感激。

$data->_field_data['nid']['entity']->field_player_birthday['und'][0]['value'];

PHP:

stdClass::__set_state(array(
    'node_field_data_field_game_players_nid' => '2931', 
    'node_title' => '1539634465', 
    'nid' => '8114', 
    'node_language' => 'tr',
    'field_data_field_player_birthday_node_entity_type' => 'node',
    '_field_data' => array ( 
        'node_field_data_field_game_players_nid' => array ( 
                'entity_type' => 'node', 
                'entity' => stdClass::__set_state(
                    array( 'vid' => '2931',

Answer 1

你很接近（因为我不得不稍微改变对象来测试，我希望这有效）...

echo $data->_field_data['node_field_data_field_game_players_nid']['entity']
           ->field_player_birthday['und'][0]['value'];

基本上不是nid，而是node_field_data_field_game_players_nid。
