如果一个json数组满足某个条件，那么在PHP解码后，如何从该数组中删除它？
一般来说，我对php非常陌生，所以如果这看起来像是一个愚蠢的问题或者我没有什么意义，我很抱歉 下面是我合并多个JSON文件的代码：如果一个json数组满足某个条件，那么在PHP解码后，如何从该数组中删除它？,php,arrays,json,Php,Arrays,Json,一般来说，我对php非常陌生，所以如果这看起来像是一个愚蠢的问题或者我没有什么意义，我很抱歉 下面是我合并多个JSON文件的代码： <?php $files = glob("*.json"); $newDataArray = []; foreach($files as $file){ $thisData = file_get_contents($file); $thisDataArray = json_decode($thisData); $newDataArray

如果查看如下所示的产品JSON数据，则产品数据位于

如果您查看产品的JSON数据，如下所示，产品数据位于用户
->产品
的深处。此外，产品本身也是一个阵列。因此，您需要两个循环来实现这一点。外部一个是循环用户，内部一个是循环每个用户的产品，并将所有有库存的取消设置为0

我认为“产品”键中还有另一个数组。
因此，您必须在$value[“产品”]上添加另一个foreach
检查该产品的库存是否为0，并根据该值修改代码
如果您只需在第一个代码块中取消设置该值，这样您就不需要为每个代码块设置另一个值，这会更好
$data = json_decode($data,true);
foreach ($data as $key => $value) {
foreach ($value['user']['products'] as $k => $v) {
if($v['stock'] == 0){
//unset it
}
}
}

你能分享一个json样本吗？当然，我会更新我的帖子。你能分享一个json样本吗？当然，我会更新我的帖子。你太棒了，我不知道为什么我不能对数组结构保持清醒的头脑。我得到了完美的结果，直到有了新的东西。太感谢你了。@JasonWaltz很高兴我能帮上忙：）你太棒了，我不知道为什么我不能把我的头绕在阵列结构上。我得到了完美的结果，直到有了新的东西。太感谢你了。@JasonWaltz很高兴我能帮忙：）
