我有这个 JSON 数据，我正在使用这个代码来匹配标题。它有效，但现在我想更进一步，列出所有低于某个价格、或高于某个价格或等于某个价格的产品
$json = '[{

echo json_encode($expected88,true);
这可以完美地工作，title但我们希望基于variant price. 一种变体可能有多个价格，如果$filter_value大于、等于或小于，任何人都可能出现。
例如，用户可能搜索最低价格为 50 的产品，因此在这种情况下，如果任何变体符合条件，则它将列出这些产品，或者用户可以搜索所有变体的价格应低于 50。
我们试过这样
$expected = array_filter($array, function ($var) use ($filter_value) {
return ($var[$filter_name] >= $filter_value);
});
但它没有用。我们再次尝试foreach和测试，但它总是给出空结果
