我有这个：
print_r($response["member"]);
我需要在name下检索levels，它位于底部，我应该如何编写它：
我想到了$response["member"][0]["Sequential"]["levels"]...？此数字也不会总是相同。
谢谢！

<?php
$nameInFirstLevelsElement = current($response["member"][0]["levels"])->Name
?>
这应该可以从第一个Name元素中检索levels。

“顺序”旁边的空白区域表示它没有值。所以那不是你要找的那个。
此外，其中一个级别表示“stdClass对象”，这意味着您可以通过->运算符访问其成员。
让我们去除一分钟无关紧要的事情。我认为这有助于您理解数据结构：
Array
(
[0] => Array
(
[Levels] => Array
(
[1391447566] => stdClass Object
(
[Level_ID] => 1391447566
[Name] => Team Membership
)
)
)
)
所以这会奏效：
$object = $response["member"][0]["Levels"][1391447566];
$name = $object->Name;
修改
如果级别索引每次都改变，那么将它拉开一点......
$levels = $response["member"][0]["Levels"];
$firstLevel = array_shift(array_values($levels));
$name = $firstLevel->Name;

答案可能是按照官方文档使用array_walk_recursive：
http://www.php.net/manual/en/function.array-walk-recursive.php
<?php
$properties = new stdClass();
$properties->names = [];
function extractNames($levels, $key, $properties) {
if (
is_object($levels) &&
array_key_exists('Name', get_object_vars($levels)) &&
array_key_exists('Level_ID', get_object_vars($levels))
) {
$properties->names[] = $levels->Name;
}
}
array_walk_recursive($response, 'extractNames', $properties);
echo print_r($properties, true);

如果＆＃39;级别下的数字＆＃39;数组不会相同，你可以使用foreach来取出名字＆＃39;信息。
foreach ($response[0]['Levels'] AS $level_key => $level_val) {
$level_name = $level_key->Name;
}
echo 'Name: '.$level_name;
如果只有一个元素，那么它会抓住它。如果“级别”下有多个号码，则会循环显示这些号码，并将每个号码分配给“＃level_name＆＃39;”，覆盖之前的任何分配。换句话说，只会捕获它找到的最后一个。
编辑：
在示例中，我错误地尝试从Name而不是$key抓取$val。这是正确的方法：
foreach ($response[0]['Levels'] AS $level_key => $level_val) {
$level_name = $level_val->Name;
}
echo 'Name: '.$level_name;
