问题描述

我想从PHP中的DateTime获取YearWeek:

I would like to get YearWeek from DateTime in PHP:

$day = \DateTime ...
$YearWeek = date("YW", date_timestamp_get($day));

但是如果一周是两年,它将不起作用:

But in case the week is on two years, it does not work:

$day // 2017-01-01
$YearWeek // I get 201752 instead of 201652

我该怎么办?

推荐答案

在的手册中,使用 o 而不是 Y

From the manual for date(), use o instead of Y:



$day = strtotime('2017-01-01');
echo date("YW", $day);  //201752
echo date("oW", $day);  //201652
