php - How to get date from week number & day number and year?

Question

I'm trying to get the date from the week number, day number and year.

For eg:

week number = 52   
day number = 4 (of week 52)  
year = 2013  

In this case, the date should be 26-12-2013.

How can I do it using PHP? I've already tried with strtotime(), but I'm confused about the formats. Can someone help?

Make use of setISODate()

<?php
$gendate = new DateTime();
$gendate->setISODate(2013,52,4); //year , week num , day
echo $gendate->format('d-m-Y'); //"prints"  26-12-2013
