OK first of all,

How can i get yesterday's date?

I mean in the format:
PHP Code:
date("d m, Y"); 
(Simply:
PHP Code:
$yesterday  = date("d") - 1;
$yesterday .= " ".date("m, Y"); 
doesn't cut it (like i thought it mite [dummy me ]) as d - 1 = 0 if its the first etc.. and the month etc :@

Next:

Is there a HTTP_SERVER_VARS[?] or getenv("?") call to get weather the current site is http:// or https:// ?

tnx

Oh also: mSQL (Microsoft SQL Server):

is there an equivilent to MySQL_Error() for it?
