需要按产品价格及其变动价格重新排列（ ASC / DESC ）。就像我有 3 个产品 ID 一样，每个产品也有 2 或 4 个不同的价格细节。喜欢 ：product 1 { variation 1 => price : 100 , variation 1 => price : 200 }product 2 { variation 3 => price : 150 , variation 4 => price : 50 }product 3 { variation 5 => price : 250 , variation 6 => price : 800 }因此，它将重新排列 (DESC)product 3 { variation 5 => price : 250 , variation 6 => price : 800 }product 1 { variation 1 => price : 100 , variation 1 => price : 200 }product 2 { variation 3 => price : 150 , variation 4 => price : 50 }因为，产品 3 的价格比产品 2 最大。{ "status": true, "message": "Product list found.", "product_data_list": [ { "product_id": "42", "product_variations": [ { "details": { "variation_id": "88", "variation_image": "http://192.168.1.1", "variation_price": "100.00" } }, { "details": { "variation_id": "89", "variation_price": "50.00" } } ] }, { "product_id": "54", "product_variations": [ { "details": { "variation_id": "128", "variation_image": "http://192.168.1.1/", "variation_price": "4000.00" } }, { "details": { "variation_id": "129", "variation_image": "http://192.168.1.1/", "variation_price": "200.00" } } ] },

您可以使用PHP usort：https : //www.php.net/manual/en/function.usort.php
基本上，usort($array, "cmp")将对来自 2 个元素的cmp($a,$b)每个组合执行回调函数，返回时置于上方，返回时置于下方，返回时不执行任何操作。请注意，排序算法使用推导，因此它只需要计算所有可能对的子集。($a,$b)$array$a$b1$a$b-10($a, $b)
在这里，我使用比较函数cmp2对产品的每个变体进行排序以获得 index 处的最高价格0，然后我使用cmp1它们按最高变体价格对产品进行排序：
usort($data->product_data_list, "cmp1");
print_r($data->product_data_list);
function cmp1($a, $b){
usort($a->product_variations, "cmp2");
usort($b->product_variations, "cmp2");
if ($a->product_variations[0]->details->variation_price == $b->product_variations[0]->details->variation_price) {
return 0;
}
return ($a->product_variations[0]->details->variation_price > $b->product_variations[0]->details->variation_price) ? -1 : 1;
}
function cmp2($a, $b){
if ($a->details->variation_price == $b->details->variation_price) {
return 0;
}
return ($a->details->variation_price > $b->details->variation_price) ? -1 : 1;
}
输出：

[status] => 1
[message] => Product list found.
[product_data_list] => Array
(
[0] => stdClass Object

[product_id] => 54

您使用 PHP 标记，但没有您的 PHP 逻辑。你能把它放在这里检查要做什么吗？
否则，解决方案可以是在 PHP 中解码 json 并在 PHP 逻辑中对其进行排序。之后，您可以将 PHP 变量编码为 json。看 ：
