从嵌套数组中获取所有对象键值

Question

嗨我有一系列对象，如下所示：

     stdClass Object
(
    [row_1_node_1] => stdClass Object
        (
            [probality] => Array
                (
                    [0] => 0.6
                    [1] => 0.4
                )

            [child_name] => Array
                (
                    [0] => node_1
                    [1] => node_2
                )

            [node_type] => decision_node

                )

        )

任何人都可以帮我解决问题 如何获取所有数字stdClass对象及其值。 我不知道从数组索引访问stdClass对象。 我怎样才能从单个阵列中获得这个 提前谢谢。

Answer 1

$array = array(
            'alevel1key1' => array(
                                'alevel2key1' => 'alevel2value1', 
                                'alevel2key2' => array(
                                                     'alevel3key1' => 'alevel3value1',
                                                     'alevel3key2' => 'alevel3value2',
                                                 ),
                             ),
            'blevel1key2' => array(
                               'blevel2key1' => 'blevel2value1'
                             ),
          );

1）现在，如果你想访问let say key alevel3key2的值，那么你可能已经完成了：

$array['alevel1key1']['alevel2key2']['alevel3key2'];

2）现在假设上面的数组是对象，那么你可能已经完成了：

$array->alevel1key1->alevel2key2->alevel3key2;
