[SOLVED] How do I get the first day of the week?

[Fog Juice]

How can I get the first day of the week? I am not good with dates.

 

I'm trying to create a function where you input the week number and the year, and it will return the timestamp of the first sunday of that week.

 

So for example, if you wanted to input week 12 of year 2007, it would return the timestamp of the sunday of that week.

i am in a bit of a time pinch, i'm supposed to be programming a schedule for a medical office that should have been finished a few days ago. This is one thing that i'm stuck on, i'd really really appreciate some help.

Use the following function

 

function getSundayOfGivenWeek($week,$year){
$sunday = strtotime('+' . 6 . ' days', strtotime('-' . (date('w', strtotime($year . '0104 +' . ($week - 1). ' weeks')) - 1) . ' days',strtotime($year . '0104 +' . ($week - 1). ' weeks')));
return $sunday;
}
  
echo strftime('%A-%Y/%m/%d', getSundayOfGivenWeek(12,2007));

                    . ' weeks');
  // Get the time of the first day of the week
  $mondayTime = strtotime('-' . (date('w', $time) - 1) . ' days',
                          $time);
  // Get the times of days 0 -> 6
  $dayTimes = array ();
  for ($i = 0; $i < 7; ++$i) {
    $dayTimes[] = strtotime('+' . $i . ' days', $mondayTime);
  }
  // Return timestamps for mon-sun.
  return $dayTimes;
}

foreach ($dayTimes as $dayTime) {
  echo (strftime('%a %Y%m%d', $dayTime) . "n");
