First date of a week

I want a First Day Of a week say开发者_开发问答 I have 45th week. Now I want to have date of the first sunday of this week. Can any one suggest me how I can go about this ?

Thank you

Searching around a bit, the most suggested is:

$year = "2009"; // date("Y");
$week = "45"; // date("W");

$firstDayOfWeek = strtotime($year."W".str_pad($week,2,"0",STR_PAD_LEFT));

print("The first day of week ".$week." of ".$year." is ".date("D, d-m-Y",$firstDayOfWeek));

Basically this comes down to letting strtotime do the work for you. You fill in "2009W45" and it'll retrieve the date for you. Pitfall here is that the week needs to be in a 2 digit format. So week 1 needs to be 01, hence the str_pad to zero-fill it.

you should strtotime and date function

some code like that

$next_sunday = strtotime('next sunday');
$next_week = strtotime('+1 week');
$next_sunday_of_next_week = strtotime('next sunday', $next_week);

hope this helps

If you have the month, day and year:

$timestamp = mktime(0, 0, 0, $month, $day, $year);
 echo date('c', $timestamp) = mktime(0, 0, 0, $month, date('d', $timestamp)-date('w', $timestamp), $year);

you could also do it this way if you have the timestamp:

echo $date('c', mktime(0, 0, 0, $month, date('d', $timestamp)-date('w', $timestamp), $year));

From: http://pinoytech.org/blog/post/get-the-first-day-of-the-week-with-an-exact-date

date($str_format, strtotime($year."W".$week."1"))

Where $str_format is the output formate according to the PHP date() function.. I use 'M d Y'
