[RESOLVED] Date of a given week

alfoxy

Hi All,

I want to get the start and end date of a given week.
E.g. Week 39 starts Sep 22 and ends Sep 28th

I did some searching and found this code

echo date("Y-m-d", strtotime(date("Y").'W'.date('W')."0"));

but i get this error

Warning: date(): Windows does not support dates prior to midnight (00:00:00), January 1, 1970 in C:\Program Files\Apache Group\Apache2\htdocs\sites\AAM Rota\inc_rota_viewer_day.php on line 57

Any ideas or suggestions would be greatly appreciated.

Thanks

Well, if you look at the strtotime string, you have "2008W390" which.. well... there is no week 390 in the year 2008; however, that should just do nothing but give you the correct first date.

Anyway... Inside of php5, this code actually works, and works well:

<?php

$week = '39';

$timestamp = strtotime(date('Y').'W'.$week."O");

echo $timestamp . "\n";
echo date('Y-m-d', $timestamp) . "\n";
echo date('Y-m-d', strtotime(date('Y').'W'.$week.' +6 days'));

Which gives the output:

1222048800
2008-09-21
2008-09-28

Inside php4, the syntax 2008W?? doesn't work. I would suggest you upgrade to a supported version of PHP.

Hi bpat1434,

Thanks for the advise but is there a way of making it work without upgrading?

Not that I'm aware of... at least not without some tricky math to get the date week then correct it for the first day of the week (Sunday or Monday)....

Ah well, thanks anyway.

There is a thread in these forums somewhere about finding the date of a given week.
here's one - not the one I was thinking of but still....

Incidentally, PHP 5 in Windows also handle dates prior to 1970. Really: you've had years in which to upgrade, and PHP 4 is officially dead. Boy have you been missing out 🙂
