Can strtotime() be used with other variables?

[amandaNHT]

Can I use strtotime() with other variables... for example:

$lastMonday = strtotime("last Monday"); 

Could I then find "3 days before that" or various other things from the result given as the variable "lastMonday"?

It has to be executable from any day... So for example if it's sun/mon/tue/wed/thu and you want to find when the last Friday was and then count back to 4 days prior for the "monday" of last week and ALSO have separate variables displaying each day from last week (monday-sunday) and the current week... (or other weeks)

The second (optional) parameter is a UNIX timestamp integer, which is what strtotime() returns, so you could chain them together if needed, e.g.:

$dateTime = strtotime('-3 days', strtotime('Last Monday')); 

Since date() also accepts the same optional 2nd parameter, you could even output that result in "human readable" format as:

echo date('Y-m-d H:i:s', strtotime('-3 days', strtotime('Last Monday')));
