如何使用PHP从日期中查找星期几的日期? [英] How to find the date of a day of the week from a date using PHP?

问题描述

如果我有一个 $date YYYY-mm-dd 并且想要获得一个特定的 $day(由 0 (YYYY-mm-dd 所在周的星期日) 到 6 (saturday)).

If I've got a $date YYYY-mm-dd and want to get a specific $day (specified by 0 (sunday) to 6 (saturday)) of the week that YYYY-mm-dd is in.

例如，如果我将 2012-10-11 作为 $date 而将 5 作为 $day, 我想得到 2012-10-12, 如果我有 0 作为 $day, 2012-10-14

For example, if I got 2012-10-11 as $date and 5 as $day, I want to get 2012-10-12, if I've got 0 as $day, 2012-10-14

你们大多数人都误解了它.我得到了一些日期，$date 并且想要获得 $date 所在的同一周的 0-6 指定的一天.

Most of you misunderstood it. I got some date, $date and want to get a day specified by 0-6 of the same week $date is in.

所以不，我不想要 $date...

So no, I don't want the day of $date...

推荐答案

我认为这就是您想要的.

I think this is what you want.

$dayofweek = date('w', strtotime($date));
$result    = date('Y-m-d', strtotime(($day - $dayofweek).' day', strtotime($date)));
