Getting timestamps from the last Saturday (every week)?

Question

first let me show you my code:

$lastWeek = date('m-d-Y', strtotime('-1 week'));

How to get a timestamp from last week. Is there any chance that I will get a timestamp from last Saturday?

I hope you know what I mean.

Many thanks.

Answer 1

what happened with

$last_sat = strtotime("last Saturday"); 

EDIT

The time should be set to '00: 00: 00 ';

echo date('d-M-Y H:i:s',$last_sat);

gives

29-Jan-2011 00:00:00
