Question

我使用此功能获取两个日期之间的所有星期五：

EXEC proc_GetQuarterlyEmailId ?, ?, ?, ?

结果：

public function getFridaysInRange($dateFromString, $dateToString)
{
    $dateFrom = new \DateTime($dateFromString);
    $dateTo = new \DateTime($dateToString);
    $dates = [];

    if ($dateFrom > $dateTo) {
        return $dates;
    }

    if (1 != $dateFrom->format('N')) {
        $dateFrom->modify('next friday');
    }

    while ($dateFrom <= $dateTo) {
        $dates[] = $dateFrom->format('Y-m-d');
        $dateFrom->modify('+1 week');
    }

    return $dates;
}

$this->getFridaysInRange('2017-01-01','2017-01-30');

上面的array:4 [▼ 0 => "2017-01-06" 1 => "2017-01-13" 2 => "2017-01-20" 3 => "2017-01-27" ]中是否有任何功能？

Answer 1

你可以像这样使用Carbon的所有力量：

$fridays = [];
$startDate = Carbon::parse($fromDate)->next(Carbon::FRIDAY); // Get the first friday.
$endDate = Carbon::parse($toDate);

for ($date = $startDate; $date->lte($endDate); $date->addWeek()) {
    $fridays[] = $date->format('Y-m-d');
}

Answer 2

对Alexey Mezenin的答案进行了轻微修改，以包括当前日期（如果是星期五）。

$fridays = [];
$startDate = Carbon::parse($fromDate)->modify('this friday'); // Get the first friday. If $fromDate is a friday, it will include $fromDate as a friday
$endDate = Carbon::parse($toDate);

for ($date = $startDate; $date->lte($endDate); $date->addWeek()) {
    $fridays[] = $date->format('Y-m-d');
}
