you when you say things aren’t working the way you think they
should. I’m just trying to make sense about why they might be
working differently in your environment than my own and whether that difference
is because there’s a gap in understanding, whether that difference is
because you’ve got a PHP related problem, or whether that difference is
because there’s a bug in drupal. We’ve got a common goal

you’re using the best technique for what you need to accomplish, and in
the absence of further information, I’m trying to clarify what the
different options are, and how I’ve accomplished similar tasks. Perhaps I’ve
read you wrong, but you seemed to be challenging my understanding of how the
variable_set/variable_get api’s are supposed to work. And seem to be
really persistent about believing this to be a bug in the drupal code, rather
than a misunderstanding about how you’re using the API’s, or a PHP
environment issue. On at least one occasion you’ve suggested that
designed behavior (that is variable_set storing values into the database) is a
bug. I *<b><span style='font-weight:bold'>know</span></b>* that’s

used or else you need to circumvent all the caching that goes on, and yes that

is an additional database cache that also is used. You may try executing

I expect that unless you delete drupal’s cache manually every time you
alter the database, you’re going to have problems getting the value back
out, unless you use variable_set to get that value in the database. All
the variables are cached, in multiple layers and multiple ways in order to
improve performance. I would encourage you to use variable_set to alter
the database values, as that’s what it’s there for. <u1:p></u1:p></span></font><o:p></o:p></p>

not supposed to overwrite a global in any version of PHP, and that the static
$conf=’’ line is a normal accepted way of initializing a static
variable caching that’s used throughout drupal. I’ve even used this
in several of my own PHP applications. I’m trying to make sense as
to why when you changed the variable names, you get different behavior.
That’s why I thought of that bug. There may be other reasons, such
as you haven’t found all of the references to the global $conf in the
drupal source code. <u1:p></u1:p></span></font><o:p></o:p></p>

use variable_get to get the last value set by variable_set (or the default if

should be done using a different structure such as your own static, global or
session construct. In multi-site hosting environments, where you want the
value of variable_get to be overridden because you’ve got to make it
dynamic based on the settings.php file in play, only then use the settings.php

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

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
