$_SERVER['HTTP_HOST'] and $_SERVER['SERVER_NAME']are different in my
circumstance,I found that the $_SERVER['SERVER_NAME']is the same with the
"ServerName" value you set in httpd.conf.

主题： [PHP] Difference between equal
$_SERVER
variables?
2003-07-24

Hi list,
Just out of curiosity I would like to know if anyone can tell me the
difference between some $_SERVER variables that generate the same output
(in
my test-file at least).
For instance, what is the difference between $_SERVER['HTTP_HOST'] and
$_SERVER['SERVER_NAME']? Can they generate different output under some
circumstances? They're always the same with me. Any recommendations on
which
to use?
I know that $_SERVER['REQUEST_URI'] can differ from 'SCRIPT_NAME' and
'PHP_SELF' (I use 'REQUEST_URI' to see what people were looking for when
they hit a 404) but can $_SERVER['SCRIPT_NAME'] and $_SERVER['PHP_SELF'] be
different?
TIA,
