感谢您抽出宝贵时间来查看我的问题。
希望这是有道理的......
我希望从JSON数组中提取数据。
在下面的数组中，我想循环通过Response＆gt; data＆gt; buckets＆gt; Equippable＆gt; 1＆gt; items＆gt; 0＆gt;节点的节点选项卡来查看它是否处于活动状态，以及它是否处于什么状态。
问题是'节点'部分可以是不同的长度，这个例子有12个结果但是接下来我只有8个等等
对于固定的结果，我会使用此
foreach ($json['Response']['data']['buckets']['Equippable']['1']['items']['0']['nodes'] as $Talentnode) {
$nodeActive[] = $Talentnode['0']['isActivated'];
$nodeState[] = $Talentnode['0']['state'];
}
当我不知道会有多少结果时，我将如何进行foreach循环？

答案 0 :(得分：2)
你的循环很好，它应该迭代所有节点，但是有很多节点。
顺便说一句：你应该把它分解成一个变量，让你的代码不那么费劲：$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
