Get previous Sunday

[Cep]

Hello,

This is a quick question but how would I go about returning the last Sunday's date in the week from the time the user views the page?

Would I use getdate() or time() with some sort of +/- combination?

[code]<?php
//Get today
$dayInWeek = date("N");
$theDay = time();

//Subtract days until it's the 7th day, Sunday
while($dayInWeek != 7){
    $theDay = $theDay-(24*60*60);
    $dayInWeek = date("N");
}

//The last Sunday was $theDay;
print date("m-d-Y", $theDay);
?>[/code]

[code=php:0]return date("l, jS F, Y", strtotime("last sunday", time()));[/code]

I would use the [url=http://www.php.net/strtotime]strtotime()[/url] function:
[code]<?php
echo 'Today is ' . date('l, F j, Y'). '<br>';
echo 'The previous Sunday was ' . date('l, F j, Y',strtotime('previous sunday')) . '<br>';
echo 'Next Sunday is ' . date('l, F j, Y',strtotime('this sunday'));
?>[/code]

I feel like such a doofus. That is a much easier, faster way to do it. Kudos ;)

I have just written a massive system that does a lot of processing of data based around dates. Daylight saving time is fun to work with!  ;)

My way was enterprisey :)
You know they just changed DST in the US? It's going to start on a different date than it used to.

British system  :P as long as PHP informs the script correctly it should all nicely plod along.
