如何对以下数组进行排序。
顶级阵列仪表类型：
“使用智能电表”， “用老式仪表
在这些内部有各种关税，也是阵列。但每个关税都有。我需要将每个米类型数组内的资费按数组中最低的第一个进行排序。我如何记住这一点我每次生成数组时都不知道关税名称。例如，tarriff名称873.03195-SDD-E1R-VAR-0002_SDD-G1R-VAR-0002每次都可能不同。

我想你想要某种这样的东西。
如果出现问题，请输入评论（我没有检查过我的代码）。
$unsortedData = [...];
$sortByTotal = function($a, b) {
$aTotal = (float)str_replace(',', '', $a['total']); // Your total value is string like "1,034.19" so making it normalized to easily compare
$bTotal = (float)str_replace(',', '', $b['total']);
return $aTotal <=> $bTotal; // read about "starship operator" in PHP 7+
};
foreach($unsortedData AS $meter => $records) {
usort($unsortedData[$meter], $sortByTotal);
}
