Question

$start = '22:00:00';
$end = '08:00:00';
$now = Carbon::now('UTC');

如何检查$ now的时间是否在时间范围内？

Answer 1

有几种方法可以通过使用Carbon来实现。最简单的方法之一是使用createFromTimeString和between方法：

$now = Carbon::now();

$start = Carbon::createFromTimeString('22:00');
$end = Carbon::createFromTimeString('08:00')->addDay();

if ($now->between($start, $end)) {
    // ¯\_(ツ)_/¯
}

Answer 2

$start = '22:00:00';
$end   = '08:00:00';
$now   = Carbon::now('UTC');
$time  = $now->format('H:i:s');

if ($time >= $start && $time <= $end) {
    ...
}

应该这样做，但不考虑日期

Answer 3

试试这个：

COUNT(DISTINCT EmployeeID)

$time = Carbon::now(); $morning = Carbon::create($time->year, $time->month, $time->day, 8, 0, 0); //set time to 08:00 $evening = Carbon::create($time->year, $time->month, $time->day, 18, 0, 0); //set time to 18:00 if($time->between($morning, $evening, true)) { //current time is between morning and evening } else { //current time is earlier than morning or later than evening }中的true会检查$time->between($morning, $evening, true)是否介于$time和$morning之间。如果你写$evening而不是检查它是否在两次之间但不包括。

实际上，您可以离开false，因为它是默认设置的，不需要。

<?php
$now = date("H");

if ($now < "20") {
    echo "Have a good day!";
}

Answer 5

请尝试以下代码，

$start = '22:00:00';
$end = '08:00:00';
$now = Carbon::now('UTC');

$nowTime = $now->hour.':'.$now->minute.':'.$now->second;

if(strtotime($nowTime) > strtotime($start) && strtotime($nowTime) < strtotime($end) ) {
    echo 'YES';
} else {
    echo 'NO';
}

Answer 6

$restrictStartTime = Carbon::createFromTime(22, 0, 0);  //carbon inbuild function which will create todays date with the given time
$restrictEndTime = Carbon::createFromTime(8, 0, 0)->addDays(1); //this will create tomorrows date with the given time
$now = Carbon::now();

if($now->gt($restrictStartTime) && $now->lt($restrictEndTime)) {
 .....
 }

Answer 7

克里斯想指出的是，如果结束时间超过午夜，那么您必须对此负责。

这不是最干净的方法，但这似乎是可行的方法。

private function isNowBetweenTimes($timezone, $startDateTime, $endDateTime) {
    $curTimeLocal = Carbon::now($timezone);
    $startTime = $curTimeLocal->copy();
    $startTime->hour = $startDateTime->hour;
    $startTime->minute = $startDateTime->minute;
    $endTime = $curTimeLocal->copy();
    $endTime->hour = $endDateTime->hour;
    $endTime->minute = $endDateTime->minute;
    if ($endTime->lessThan($startTime))
        $endTime->addDay();

    return ($curTimeLocal->isBetween($startTime, $endTime));
}

此示例仅关心小时和分钟，而不关心秒，但是您也可以轻松地复制它们。这样做的关键是先比较开始时间和结束时间，然后再将它们与当前时间进行比较；如果结束时间小于开始时间，则在结束时间前增加一天。

Answer 8

您可以反向检查算法。

<?php
$pushChannel = "general";

$now = Carbon::now();

$start = Carbon::createFromTime(8, 0);
$end = Carbon::createFromTime(22, 0);

if (!$now->between($start, $end)) {
     $pushChannel = "silent";

Answer 9

对于支持所有开始和结束时间范围的完整解决方案，您可以使用按位XOR。

/*
 * must using hours in 24 hours format e.g. set 0 for 12 pm, 6 for 6 am and 13 for 1 pm
 */
private $startTime = '0';
private $endTime = '6';
    

$currentHour = \Carbon\Carbon::now()->hour;
$start = $this->startTime > $this->endTime ? !($this->startTime <= $currentHour) : $this->startTime <= $currentHour;
$end = $currentHour < $this->endTime;


if (!($start ^ $end)) {
  //Do stuff here if you want exactly between start and end time
}

Answer 10

试试这个：

foreach ($ids_array as $id) {
    $O = new Object($id);

    // stuff and things
}
