CARBON 使用工作日数获取日期范围之间的所有日期

Question

我有一个指示工作日编号的数组，例如这个数组：

[1, 3, 5]

表示星期一、星期三和星期五，给定一个日期范围，如何获取该范围内所有星期一、星期三和星期五的日期。

我正在使用 Laravel 和 Carbon。

Answer 1

检查此代码：

function weekDaysBetween($requiredDays, $start, $end){
    $startTime = Carbon::createFromFormat('d-m-Y', $start);
    $endTime = Carbon::createFromFormat('d-m-Y', $end);

    $result = [];

    while ($startTime->lt($endTime)) {
        
        if(in_array($startTime->dayOfWeek, $requiredDays)){
            array_push($result, $startTime->copy());
        }
        
        $startTime->addDay();
    }

    return $result;
}

你可以这样称呼它：

weekDaysBetween([1,2, 3], "01-09-2021", "01-10-2021")

结果会是这样的：

[
    "2021-09-01T22:02:21.000000Z",
    "2021-09-06T22:02:21.000000Z",
    "2021-09-07T22:02:21.000000Z",
    "2021-09-08T22:02:21.000000Z",
    "2021-09-13T22:02:21.000000Z",
    "2021-09-14T22:02:21.000000Z",
    "2021-09-15T22:02:21.000000Z",
    "2021-09-20T22:02:21.000000Z",
    "2021-09-21T22:02:21.000000Z",
    "2021-09-22T22:02:21.000000Z",
    "2021-09-27T22:02:21.000000Z",
    "2021-09-28T22:02:21.000000Z",
    "2021-09-29T22:02:21.000000Z"
]

Answer 2

您可以使用->daysUntil()->filter()

function weekDaysBetween($requiredDays, $start, $end)
{
  return CarbonImmutable::createFromFormat('d-m-Y', $start)
    ->daysUntil(CarbonImmutable::createFromFormat('d-m-Y', $end))
    ->filter(static fn (CarbonImmutable $date) => in_array($date->dayOfWeek, $requiredDays, true));
}

CARBON 使用工作日数获取日期范围之间的所有日期

CARBON Get all dates between date range using number of the weekday
