date("D")--1; or how to do it?

[Anon]

Hi all,

I use this simple code to print the day of the week:

$today = date("D"); // Returns "Fri"

and my question is How can I print out the day before "Fri", I wanna print "Thu"?
I tried:

$yesterday = date("D")-1;

But didn't work. Didn't print "Thu".

Thanks.

$yesterday = date ('D', time () - 86400);

$yesterday = date("D", mktime(0, 0, 0, date("m"), date("d")-1, date("Y")));
