Maybe strtotime('-1 day') would work. [shrug]
You could also use http://php.net/mktime
mktime(date('m'), -1); //This should be 24 hours before 'now', I think...
Or maybe mktime(date('m'), date('d) -1);
Whichever it is, PHP's mktime does the right thing even if you use, like:
mktime(6, 0); //This is really May 31st, not June 0. PHP knows.
