true, I was mistaken about the variables being instatitated. But these values
are initially loaded from the database by the variable_init function, called in
the drupal bootstrap process before settings.php is loaded. Yes you can
override these in settings.php, in which case the database value doesn’t
matter, but hey are still meant to be site configuration values that do not
change. As the settings.php file indicates you don’t normally use
this method, unless you’re rally trying to something vhost specific.
They are not intended to house global variables that you intend to change
during the page load. Variable_set is designed to change the
database given values and is functioning as designed. It’s used by
the admin pages to alter the site specific values. <u1:p></u1:p></span></font><o:p></o:p></p>

cache. It’s only in weird multi-site hosting cases that you
would ever be overriding the values retrieved by variable_get in settings.php.
It is not the preferred method of handling values that you expect to
change during a page load or between page loads on a site. <u1:p></u1:p></span></font><o:p></o:p></p>

that you can uncomment and set initial variable values in settings.php with the
$conf array. In doing so, and not seeing my variables set when retrieving
using variable_get, I discovered that conf_init(), when called to initialize
the configure file path, it sets $conf to a string. I know that since it
initializes settings.php within the context it conceptually SHOULD reset it to
a variable, but it doesn't. I proved this by changing the variable array
name in settings.php, variable_get, variable_set, variable_init and conf_init
to $config_vars and the values I initialized in settings.php were reflected
when my application later retrieved them using variable_get.<u3:p></u3:p><u1:p></u1:p><o:p></o:p></span></font></p>

(or in my case, $config_vars. Is this on purpose? I see that
variable_set will not only set the cached variable but will also set into the
