Get the date of next monday, tuesday, etc
提问by Adrian Sarli
I would like to find the date stamp of monday, tuesday, wednesday, etc. If that day hasn't come this week yet, I would like the date to be this week, else, next week. Thanks!
我想找到星期一、星期二、星期三等的日期戳。如果这周还没到，我希望日期是本周，否则，下周。谢谢！

See strtotime()
strtotime('next tuesday');
You could probably find out if you have gone past that day by looking at the week number:
通过查看周数，您可能会发现自己是否已经过了那一天：
$nextTuesday = strtotime('next tuesday');
$weekNo = date('W');
$weekNoNextTuesday = date('W', $nextTuesday);
if ($weekNoNextTuesday != $weekNo) {
//past tuesday
}

I know it's a bit of a late answer but I would like to add my answer for future references.
我知道这有点晚了，但我想添加我的答案以供将来参考。
// Create a new DateTime object
$date = new DateTime();
// Modify the date it contains
$date->modify('next monday');
// Output
echo $date->format('Y-m-d');
The nice thing is that you can also do this with dates other than today:
好消息是您还可以使用今天以外的日期执行此操作：
// Create a new DateTime object
$date = new DateTime('2006-05-20');
// Modify the date it contains
$date->modify('next monday');
// Output
echo $date->format('Y-m-d');
To make the range:
要制作范围：
$monday = new DateTime('monday');
// clone start date
$endDate = clone $monday;
// Add 7 days to start date
$endDate->modify('+7 days');
// Increase with an interval of one day
$dateInterval = new DateInterval('P1D');
$dateRange = new DatePeriod($monday, $dateInterval, $endDate);
foreach ($dateRange as $day) {
echo $day->format('Y-m-d')."<br />";
}

The question is tagged "php" so as Tom said, the way to do that would look like this:
正如汤姆所说，这个问题被标记为“php”，这样做的方法是这样的：
date('Y-m-d', strtotime('next tuesday'));

Sorry, I didn't notice the PHP tag - however someone else might be interested in a VB solution:
抱歉，我没有注意到 PHP 标签 - 但是其他人可能对 VB 解决方案感兴趣：
Module Module1
Sub Main()
Dim d As Date = Now
Dim nextFriday As Date = DateAdd(DateInterval.Weekday, DayOfWeek.Friday - d.DayOfWeek(), Now)
Console.WriteLine("next friday is " & nextFriday)
Console.ReadLine()
End Sub
End Module

if you want to find Monday then 'dayOfWeek' is 1 if it is Tuesday it will be 2 and so on.
如果你想找到星期一，那么 'dayOfWeek' 是 1，如果是星期二，它将是 2，依此类推。
var date=new Date();
getNextDayOfWeek(date, 2);
// this is for finding next tuesday
// 这是为了寻找下周二
function getNextDayOfWeek(date, dayOfWeek) {
// Code to check that date and dayOfWeek are valid left as an exercise ;)
var resultDate = new Date(date.getTime());
resultDate.setDate(date.getDate() + (7 + dayOfWeek - date.getDay()) % 7);
return resultDate;
}
Hope this will be helpfull to you, thank you
希望这对你有帮助，谢谢

If I understand you correctly, you want the dates of the next 7 days?
如果我理解正确，您想要接下来 7 天的日期吗？
You could do the following:
您可以执行以下操作：
for ($i = 0; $i < 7; $i++)
echo date('d/m/y', time() + 86400 * $i);
Check the documentation for the date function for the format you want it in.
检查日期函数的文档以获取您想要的格式。

For some reason, strtotime('next friday')display the Friday date of the current week. Try this instead:
出于某种原因，strtotime('next friday')显示当前周的星期五日期。试试这个：
//Current date 2020-02-03
$fridayNextWeek = date('Y-m-d', strtotime('friday next week'); //Outputs 2020-02-14
$nextFriday = date('Y-m-d', strtotime('next friday'); //Outputs 2020-02-07

The PHP documentation for time()shows an example of how you can get a date one week out. You can modify this to instead go into a loop that iterates a maximum of 7 times, get the timestamp each time, get the corresponding date, and from that get the day of the week.
time()的PHP 文档显示了一个示例，说明如何获取一周外的日期。您可以将其修改为进入最多迭代 7 次的循环，每次获取时间戳，获取相应的日期，并从中获取星期几。
