在 Json 数组输出短按产品价格 ASC 和 DESC
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。

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：stdClass Object( [status] => 1 [message] => Product list found. [product_data_list] => Array ( [0] => stdClass Object ( [product_id] => 54 [product_variations] => Array ( [0] => stdClass Object ( [details] => stdClass Object ( [variation_id] => 128 [variation_image] => http://192.168.1.1/ [variation_price] => 4000.00 ) ) [1] => stdClass Object ( [details] => stdClass Object ( [variation_id] => 129 [variation_image] => http://192.168.1.1/ [variation_price] => 200.00 ) ) ) ) [1] => stdClass Object ( [product_id] => 55 [product_variations] => Array ( [0] => stdClass Object ( [details] => stdClass Object ( [variation_id] => 135 [variation_image] => http://192.168.1.1/ [variation_price] => 2600.00 ) ) [1] => stdClass Object ( [details] => stdClass Object ( [variation_id] => 133 [variation_image] => http://192.168.1.1/RGB_api/DUMMY [variation_price] => 1600.00 ) ) [2] => stdClass Object ( [details] => stdClass Object ( [variation_id] => 134 [variation_image] => http://192.168.1.1/RGB_api/DUMMY [variation_price] => 1200.00 ) ) ) ) [2] => stdClass Object ( [product_id] => 42 [product_variations] => Array ( [0] => stdClass Object ( [details] => stdClass Object ( [variation_id] => 88 [variation_image] => http://192.168.1.1 [variation_price] => 100.00 ) ) [1] => stdClass Object ( [details] => stdClass Object ( [variation_id] => 89 [variation_price] => 50.00 ) ) ) ) )) -

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 ：https://www.php.net/manual/fr/function.json-encode.phphttps://www.php.net/manual/fr/function.json-decode.php
