您可以更改要用于筛选的结构
$allowedVals = ['exchange' => ["OTC", "NYSE"], 'price' => [28.97,0.268]];
$result = [];
foreach ($nResult as $key => $value) {
foreach ($allowedVals as $key1 => $value1) {

如何过滤？删除项目？保管物品？是否根据关键字名称或值进行筛选？请编辑您的问题，以包括适当的解释，并向我们显示预期结果以及您当前的代码为您提供了什么。使用键和值筛选数组，数组包含筛选键和值所需的所有键，例如，我需要筛选EXchange OTC和NYSE，如例外结果所示，您将如何筛选价格？或者任何其他键值？@Rahul是的，我也想要过滤器价格，你能建议meAll filter的标准必须匹配，或者其中任何一个都应该匹配吗？检查一下我的答案！我修改了你的筛选条件数组。
