Need function to find previous thursday OR friday

Hi :-)
I need a function that will return the date for the previus Thursday OR Friday (decided from a $parameter).

The date returned has to be at least 8 days before today - I will be calling this function twice to get the last full week going from friday -> thursday next week.

So today I would need to find 2 dates - Friday 10/24 and Thursday 10/30 - then use them later to perform a query.

I was building this function, where I owuld send 5 for thursday and 6 for friday - but it don't really work ::

function getStartDates($day=6){
      $dow = date("w"); //monday == 1
      $offset = ($dow -1);
      if ($offset <0) {
            $offset = $day;
      }
      return date("Ymd", mktime(0,0,0,date('m'), date('d')-$offset-1, date('Y') ));
}

Hope that some of you guys can help me out here :-)

Here ya go. php built in function strtotime();
<?php echo date('m/d/Y', strtotime("last Thusday")); ?>
<?php echo date('m/d/Y', strtotime("last Friday")); ?>

Open in new window

By the way, the strtotime() function returns a unix timestamp which is why I wrapped it in a date() tag The above code will echo 10/30/2008 and 10/31/2008

Hello trg_dk,

You should look at the strtotime function http://uk3.php.net/manual/en/function.strtotime.php

For example

$dateLastThursday = date("Y-m-d",strtotime("last Thursday"));


Regards,

:-O OK this just blows my head clean off :-)

Thank you so much - feel I should have found this on php.net ??
Are these function undocumented or did I fail miserably in the "Googling" categoru ?

Thanks again,
Mark

The php manual should be your best friend. :-) If all else fails, check php.net.

Glad I could help.
