Question

我正在创建一个网站，只允许在特定的交付时间范围内交付。

以下是我正在寻找的一个例子：

FakeCompany周三发布，允许客户在周五至周二下订单，截止时间为周二晚上11点。

如果允许订购，我需要确定客户何时登录（周五至周二晚上11点之间）。我还需要知道他们需要多长时间才能订购。

我知道星期五是5的PHP date('N')函数：

date('N', strtotime('Friday'));

和星期二是1：

date('N', strtotime('Tuesday'));

这些时间范围可能会发生变化，因此我需要一个简单的解决方案。

这是我的开始，现在我迷失了如何做到这一点。

//Set today and get from database start / end days and end time
$today = (int)date('N');
$startDay = (int)date('N', strtotime('Friday'));
$endDay = (int)date('N', strtotime('Tuesday'));
$endDayTime = '11:00:00';
//If today is before start date
if($today >= $startDay && $today <= $endDay){
    //This works only if the end date is not the following week
    //It also needs to be before end day time!
}

我想我需要根据DAY（星期五）获取一周的日期，如果周五没有通过星期五或者星期五的下周，请将其转换为星期五，并在结束日期进行相同的处理。

然后我需要知道今天是否在这些日期/时间之间。

Answer 1

$now     = new DateTime();
$tuesday = new DateTime('last Tuesday');
$friday  = new DateTime('Friday 11pm');

if ($tuesday < $now && $now < $friday) {
    $interval = $friday->diff($now);
    echo $interval->format('%d day %h hours %i minutes left to order');
}
else {
    echo "you can't order now";
}

这是一个检查今天是批准日的功能，如果它的星期二也确定它是在晚上11点之前：

/*
Acceptable days:

5 - friday
6 - saturday
7 - sunday
1 - monday
2 - tuesday
*/

//Can they order today?
if(in_array(date('N'),array(1,2,5,6,7))){
    //if today is tuesday is it before 11pm?
    if(date('N') == 2){
        if(date('H')<23){
             //23 = 11pm in 24 hour time 
             //Then can order
        }
        else{
             //Then CANT order
        }
    }
    //Its not tuesday so we dont care what time it is they can order
}

Answer 3

结束那天我认为你可以这样做：

$endDay = (int)date('N', strtotime('Friday') + 3 *  24 * 3600 + 23 * 3600);

strtotime（'星期五'）到星期五，加上3天24小时，它将是星期二凌晨0点。然后你在晚上11点结束时增加了23个小时的时间。

$today = (int)date('N');
$startDay = (int)date('N', strtotime('Friday'));
$endDay = (int)date('N', strtotime('Friday') + 3 *  24 * 3600 + 23 * 3600); 

//If today is before start date
if($today >= $startDay && $today <= $endDay){
    //now it works
}

Answer 4

这正是我要找的。

提供的日期可能不是本周甚至是本月，所以我们需要根据日期确定一周中的哪一天，并根据今天将当天或下周的日期设置为当天（有点混乱）。

echo $output;

当前日期是否在PHP中指定的日期/时间范围内
