Question

我正在尝试创建一个交货时间估算器，该估算器基于今天的日期来显示接收物品需要多少天。

一切工作都很好。我要坚持的最后一部分是如何设置日期，以便每天太平洋时间下午2点将日期更改为第二天。

现在，我已将其设置为使用太平洋时间。只需要将更改日期更改为太平洋标准时间下午2点至第二天的更改日期即可。

我考虑过只是更改时区，但不确定采用夏令时是否会成为使用这种方法要考虑的问题。

我添加了下面正在使用的代码：

<?php
if ((strlen(ini_get('date.timezone')) < 1) && function_exists('date_default_timezone_set')) {
    date_default_timezone_set('America/Los_Angeles');
}

function getNextMondayDate($date) {
    $day = date('w', $date);
    if ($day==0) {
        $ret = strtotime("+1 day", $date);
    } else if ($day==6) {
        $ret = strtotime("+2 day", $date);
    } else {
        $ret = strtotime("now", $date);
    }
    return $ret;
}

function businessDays($days, $time) {       
    for ($i=0; $i<$days; $i++) {
        $time = strtotime('+1 day', $time);
        $day = date('w',$time);
        if ($day==0) {
            $time = strtotime('+1 day', $time);
        } else if ($day==6) {
            $time = strtotime('+2 day', $time);
        }
    }
    return $time;
}

$date =  date("l, F jS");
$dateStart = getNextMondayDate(strtotime("now"));

  if (date('w')==6 || date('w')==0){
// If the order is placed on Saturday or Sunday...
// THe numbers you see below are measured in days.  In the example below
// The delivery times for standard shipping are from 2-4 days from today
    $dateStandardMinMG = date("l, F jS",getNextMondayDate(businessDays(2,$dateStart)));
    $dateStandardMaxMG = date("l, F jS",getNextMondayDate(businessDays(4,$dateStart)));
    $dateExpressMinMG = date("l, F jS",getNextMondayDate(businessDays(0,$dateStart)));
    $dateExpressMaxMG = date("l, F jS",getNextMondayDate(businessDays(1,$dateStart)));
}else{
// Otherwise, use these estimates
    $dateStandardMinMG = date("l, F jS",getNextMondayDate(businessDays(3,$dateStart)));
    $dateStandardMaxMG = date("l, F jS",getNextMondayDate(businessDays(5,$dateStart)));
    $dateExpressMinMG = date("l, F jS",getNextMondayDate(businessDays(1,$dateStart)));
    $dateExpressMaxMG = date("l, F jS",getNextMondayDate(businessDays(2,$dateStart)));
  }
?>

如果我理解正确，如果输入时间超过2 PM，您想在计算中加上+1天吗？为了使它与您的方法保持一致，我将为日期添加一个日期格式，并像在工作日中一样使用它

自从businessDays（）计算出交货时间以来，我认为这很合适

function businessDays($days, $time) {
    // Past 2 PM check should be outside the for loop
    $hours = date('G', $time);
    $weekend = date('w',$time);
    if ($hours > 14 AND $weekend != 0 AND $weekend !=6) {
        $time = strtotime('+1 day', $time); 
    }  
    for ($i=0; $i<$days; $i++) {
        $time = strtotime('+1 day', $time);
        $day = date('w',$time);
        if ($day==0) {
            $time = strtotime('+1 day', $time);
        } else if ($day==6) {
            $time = strtotime('+2 day', $time);
        }
    }
    return $time;
}

因此，您正在寻找一个函数来返回距当前日期一定天数的下一个工作日–除非是在周末或下午2点之后，否则您希望下一个工作日是一定的天数从下一个工作日开始的几天？这应该做到这一点。我把它们都铺满了，所以应该很容易理解。

function getDeliveryDay(int $days, int $date = null):int {
    if ($date === null) {
        $date = time();
    }
    $base = "now";
    if (date("H", $date) >= 14) {
        // if it's late, calculate from tomorrow
        $days++;
    }
    if (in_array(date("w", $date), [0, 6])) {
        // if it's a weekend, calculate from monday
        $base = "next monday";
    }
    for ($i = 0; $i <= $days; $i++) {
        // make sure delivery day isn't Saturday or Sunday
        // don't count those days in processing time either
        $result = strtotime("$base +$i days", $date);
        $w = date("w", $result);
        if (in_array($w, [0, 6])) $days++;
    }
    return $result;
}

测试（星期四3:00）：

echo date("l, F jS", getDeliveryDay(0)) . "\n"; // should be Friday
echo date("l, F jS", getDeliveryDay(1)) . "\n"; // should be Monday
echo date("l, F jS", getDeliveryDay(2)) . "\n"; // should be Tuesday
echo date("l, F jS", getDeliveryDay(3)) . "\n"; // should be Wednesday
echo date("l, F jS", getDeliveryDay(4)) . "\n"; // should be Thursday
echo date("l, F jS", getDeliveryDay(5)) . "\n"; // should be Friday

输出：

Friday, April 5th
Monday, April 8th
Tuesday, April 9th
Wednesday, April 10th
Thursday, April 11th
Friday, April 12th

使用您的原始代码：

$dateStandardMinMG = date("l, F jS", getDeliveryDay(2));
$dateStandardMaxMG = date("l, F jS", getDeliveryDay(4));
$dateExpressMinMG = date("l, F jS", getDeliveryDay(0));
$dateExpressMaxMG = date("l, F jS", getDeliveryDay(1));
