CarbonPeriod知らなかった

はじめに

こんばんは。

Carbonよく使っているのですが、 最近 CarbonPeriodの存在を知りました。

github.com

本題

<?php

use Carbon\CarbonImmutable;
use Carbon\CarbonPeriodImmutable;

$period = CarbonPeriodImmutable::create(
    CarbonImmutable::now()->startOfMonth(),
    CarbonImmutable::now()->endOfMonth(),
);

dd(array_map(
    static fn(CarbonImmutable $d) => $d->format('Y-m-d H:i:s'), 
    $period->toArray()
));

/**
array:30 [▼
  0 => "2023-09-01 00:00:00"
  1 => "2023-09-02 00:00:00"
  2 => "2023-09-03 00:00:00"
  3 => "2023-09-04 00:00:00"
  4 => "2023-09-05 00:00:00"
  5 => "2023-09-06 00:00:00"
  6 => "2023-09-07 00:00:00"
  7 => "2023-09-08 00:00:00"
  8 => "2023-09-09 00:00:00"
  9 => "2023-09-10 00:00:00"
  10 => "2023-09-11 00:00:00"
  11 => "2023-09-12 00:00:00"
  12 => "2023-09-13 00:00:00"
  13 => "2023-09-14 00:00:00"
  14 => "2023-09-15 00:00:00"
  15 => "2023-09-16 00:00:00"
  16 => "2023-09-17 00:00:00"
  17 => "2023-09-18 00:00:00"
  18 => "2023-09-19 00:00:00"
  19 => "2023-09-20 00:00:00"
  20 => "2023-09-21 00:00:00"
  21 => "2023-09-22 00:00:00"
  22 => "2023-09-23 00:00:00"
  23 => "2023-09-24 00:00:00"
  24 => "2023-09-25 00:00:00"
  25 => "2023-09-26 00:00:00"
  26 => "2023-09-27 00:00:00"
  27 => "2023-09-28 00:00:00"
  28 => "2023-09-29 00:00:00"
  29 => "2023-09-30 00:00:00"
]
*/

めっちゃ楽。

これをもっと早く知りたかった。。。

降順にしたい場合は array_reverse を使えばできそう

<?php

use Carbon\CarbonImmutable;
use Carbon\CarbonPeriodImmutable;

$period = CarbonPeriodImmutable::create(
    CarbonImmutable::now()->startOfMonth(),
    CarbonImmutable::now()->endOfMonth(),
);
dd(array_map(
    static fn(CarbonImmutable $d) => $d->format('Y-m-d H:i:s'),
    array_reverse($period->toArray())
));

/**
array:30 [▼
  0 => "2023-09-30 00:00:00"
  1 => "2023-09-29 00:00:00"
  2 => "2023-09-28 00:00:00"
  3 => "2023-09-27 00:00:00"
  4 => "2023-09-26 00:00:00"
  5 => "2023-09-25 00:00:00"
  6 => "2023-09-24 00:00:00"
  7 => "2023-09-23 00:00:00"
  8 => "2023-09-22 00:00:00"
  9 => "2023-09-21 00:00:00"
  10 => "2023-09-20 00:00:00"
  11 => "2023-09-19 00:00:00"
  12 => "2023-09-18 00:00:00"
  13 => "2023-09-17 00:00:00"
  14 => "2023-09-16 00:00:00"
  15 => "2023-09-15 00:00:00"
  16 => "2023-09-14 00:00:00"
  17 => "2023-09-13 00:00:00"
  18 => "2023-09-12 00:00:00"
  19 => "2023-09-11 00:00:00"

  27 => "2023-09-03 00:00:00"
  28 => "2023-09-02 00:00:00"
  29 => "2023-09-01 00:00:00"

終わりに

よく使っているライブラリでも、意外と知らないのがあるんですね〜。

現場からは以上です。
