get unix timestamp using php

Question

Suppose i know that today's day is monday. How do i use mktime() in php to get unix timestamp for last friday and the friday before that??

suppose today's date is 17-01-2011 and its a monday. Then i want the timestamp for 14-01-2011 00:00:00 and 7-01-2011 00:00:00.

Answer 1

check out strtotime http://php.net/manual/en/function.strtotime.php ..solves most of that kinda issues - otherwise you must strap the date yourself
