Answer 1

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

Try this code.

 <?php

    function change_date($week_num, $day) {
      $timestamp    = strtotime(date('Y') . '-W' . $week_num . '-' . $day);
      return $timestamp;
    }
   $timestamp = change_date(52, 4);
    echo date('d-m-Y', $timestamp);
?>
