我可以根据今年的星期数，找出星期一的日期。

有人能帮我这个代码吗？ / p>

谢谢。

这将提供一周的星期一今年：

  $ thisYear = date（'Y'）; 
 $ weekNum = 40; 
 
 $ date = date（'Y-m-d'，strtotime（$ thisYear-W $ weekNum-1））; //输出2013-09-30 
  

I can`t figure out the code to get the date from monday depending on the week number of this year.

could someone help me with this code?

解决方案

This will provide the Monday of a certain week this year:

$thisYear = date('Y');
$weekNum = 40;

$date = date('Y-m-d', strtotime("$thisYear-W$weekNum-1"));  // Outputs 2013-09-30
