PHP 舍入时间()向上(未来)到下一个 5 分钟的倍数


PHP round time() up (future) to next multiple of 5 minutes

如何将time()的结果四舍五入(朝向未来)到下一个 5 分钟的倍数?

 $now = time();     
 $next_five = ceil($now/300)*300;

这将给你下一轮五分钟(总是大于或等于当前时间)。

根据您的描述,我认为这就是您需要的。

尝试:

$time = round(time() / 300) * 300;

试试这个函数:

function blockMinutesRound($hour, $minutes = '5', $format = "H:i") {
   $seconds = strtotime($hour);
   $rounded = round($seconds / ($minutes * 60)) * ($minutes * 60);
   return date($format, $rounded);
}
//call 
 blockMinutesRound('20:11');// return 20:10

对于使用Carbon的人(例如使用Laravel的人),这可以帮助:

/**
 * 
 * @param 'Carbon'Carbon $now
 * @param int $nearestMin
 * @param int $minimumMinutes
 * @return 'Carbon'Carbon
 */
public static function getNearestTimeRoundedUpWithMinimum($now, $nearestMin = 30, $minimumMinutes = 8) {
    $nearestSec = $nearestMin * 60;
    $minimumMoment = $now->addMinutes($minimumMinutes);
    $futureTimestamp = ceil($minimumMoment->timestamp / $nearestSec) * $nearestSec; 
    $futureMoment = Carbon::createFromTimestamp($futureTimestamp);
    return $futureMoment->startOfMinute();
}

这些测试断言通过:

public function testGetNearestTimeRoundedUpWithMinimum() {
    $this->assertEquals('2018-07-07 14:00:00', TT::getNearestTimeRoundedUpWithMinimum(Carbon::parse('2018-07-06 14:12:59'), 60, 23 * 60 + 10)->format(TT::MYSQL_DATETIME_FORMAT));
    $this->assertEquals('2018-07-06 14:15:00', TT::getNearestTimeRoundedUpWithMinimum(Carbon::parse('2018-07-06 14:12:59'), 15, 1)->format(TT::MYSQL_DATETIME_FORMAT));
    $this->assertEquals('2018-07-06 14:30:00', TT::getNearestTimeRoundedUpWithMinimum(Carbon::parse('2018-07-06 14:12:59'), 30, 10)->format(TT::MYSQL_DATETIME_FORMAT));
    $this->assertEquals('2018-07-06 16:00:00', TT::getNearestTimeRoundedUpWithMinimum(Carbon::parse('2018-07-06 14:52:59'), 60, 50)->format(TT::MYSQL_DATETIME_FORMAT));
    $this->assertEquals(Carbon::parse('tomorrow 15:00:00'), TT::getNearestTimeRoundedUpWithMinimum(Carbon::parse('16:30'), 60, 60 * 22 + 30));
}

使用碳:

Carbon::createFromTimestamp(round(time() / 300) * 300)
