有一个时间对应温度数组，然后根据自定义时间段获取该时间段平均温度，用laravel优雅的显示出来
管理员 发布于 4年前 325
需求：
1.每天时间与温度对应的一个有一个数组；（已有）
['2020-11-09 00:00:00' => 0,
'2020-11-09 01:00:00' => 0,
'2020-11-09 02:00:00' => -1,
'2020-11-09 03:00:00' => -1,
'2020-11-09 04:00:00' => -2,
'2020-11-09 05:00:00' => -2,
...]
2.用户自定义的时间段 比如 4点到8点/8点到11点等等;
3.求出每个不同时间段，平均温度值！（注意：优雅）;
代码：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Carbon;
use Illuminate\Support\Collection;
class TestController extends Controller
{
public function __invoke(Request $request)
{
$dates = [
['2020-11-09 04:00:00', '2020-11-09 08:00:00'],
['2020-11-09 08:00:00', '2020-11-09 11:00:00'],
['2020-11-09 11:00:00', '2020-11-09 15:00:00'],

['2020-11-10 11:00:00', '2020-11-12 15:00:00'],
];
return Collection::make($dates)->map(function ($val) {
$avg = $this->getAvgItem($val[0], $val[1])->avg();
return [
'start' => $val[0],
'end' => $val[1],
'avg' => $avg
];
});
}
protected function getAvgItem(string $start, string $end)
{
$start_date = Carbon::parse($start);
$end_date = Carbon::parse($end);
$data = $this->getTemperature();
return Collection::make($data)->filter(function ($key, $val) use ($start_date, $end_date) {
$now_date = Carbon::parse($val);
return $now_date->gte($start_date) && $now_date->lte($end_date);
});
}
protected function getTemperature()
{
return [

'2020-11-10 15:00:00' => 13,
];
}
}总结：基于laravel集合极其优雅的显示出来
