Php JSON数组上的foreach循环
谢谢你花时间看我的问题 希望这有意义 我想从JSON数组中提取数据 在下面的数组中，我想在Response>data>Bucket>Equipable>1>items>0>节点的nodes选项卡中循环，看看它是否处于活动状态，如果是，它是什么状态 问题是“节点”部分可以是不同的长度，这个示例有12个结果，但下一个示例只有8个结果，以此类推 对于一个固定的结果，我会使用这个Php JSON数组上的foreach循环,php,arrays,json,foreach,Php,Arrays,Json,Foreach,谢谢你花时间看我的问题 希望这有意义 我想从JSON数组中提取数据 在下面的数组中，我想在Response>data>Bucket>Equipable>1>items>0>节点的nodes选项卡中循环，看看它是否处于活动状态，如果是，它是什么状态 问题是“节点”部分可以是不同的长度，这个示例有12个结果，但下一个示例只有8个结果，以此类推 对于一个固定的结果，我会使用这个 foreach ($json['Response']['data']['buckets']['Equippable']['1

你的循环很好，不管有多少个节点，它都应该在所有节点上迭代 顺便说一句：你应该把它分解成一个变量，这样你的代码就不会那么费劲了：
$nodes = $json['Response']['data']['buckets']['Equippable']['1']['items']['0']['nodes'];
foreach($nodes as $talentNode) {
// Perform operations on each nodes...
if($talentNode['isActivated'])
$nodesActive[] = $talentNode;
$nodeState[] = $talentNode['state'];
}
$nodesActive; // Array of the nodes active
$nodeState; // Array with the state of each node

对于
节点节点数组中的任何数量的元素，您的代码都可以正常工作。为什么你认为如果其中有更多或更少的值就不会…？谢谢，使用你更新的代码版本，我如何找到哪些节点的[isActivated]=>1和[state]=>10@Ashley我已经更新了我的代码示例，以显示您将如何执行该操作。谢谢，使用您更新的代码版本，我如何找到已激活的节点=>1和[状态]=>10@Ashley我已经更新了我的代码示例，以展示您将如何执行该操作
