How does the following look?
variables_order string
Sets the order of the EGPCS (Environment, Get, Post, Cookie, and
Server) variable parsing. For example, if variables_order is set to
"SP" then PHP will create the superglobals $_SERVER and $_POST, but not
create $_ENV, $_GET, and $_COOKIE. Setting to "" means no superglobals
will be set.
If the deprecated register_globals directive is on (removed as of PHP
6), then variables_order also configures the order the ENV, GET, POST,
COOKIE and SERVER variables are populated in global scope. So for
example if variables_order is set to "EGPCS", register_globals is
enabled, and both $_GET['action'] and $_POST['action'] are set, then
$action will contain the value of $_POST['action'] since "P" is after
the "G" in the examples directive value.
$_REQUEST is also affected by this order.

Description:
------------
In "Actual Result" I have copied the current "variables_order"
description from the manual.
It looks if it was copied from the "register_globals - friendly"
description of "gpc_order", but AFAIK these two parameters don't do the
same!
If you set "variables_order" to "GP", PHP will _not_ "overwrite any GET
method variables with POST-method variables of the same name" - that's
why $_GET etc. have been invented.
Since "register_globals" has been removed from CVS-HEAD, I think this
description is misleading (at least it was to me).
As far as I can see the order of the variables does not matter if you
don't have register_globals anymore. It's only a question of which
variables will be created at all. Only if you still use
register_globals the last sentence makes sense, but this should not be
the default anymore (IMO).
Expected result:
----------------
Perhaps something like that:
variables_order string
Set the order of the EGPCS ($_ENV, $_GET, $_POST, $_COOKIE,
$_SERVER) variable parsing. The default setting of this directive is
"EGPCS". Setting this to "GP", for example, will cause PHP to
completely ignore environment variables, cookies and server variables,
and to created only the $_GET and $_POST superglobals.
If register_globals is still used, variables_order also configures the
order ENV, GET, POST, COOKIE and SERVER variables are populated in
global scope. Setting this to "GP" with register_globals enabled, will
cause PHP to overwrite any GET method variables with POST-method
variables of the same name.
[REGISTER-GLOBALS-WARNING]
[REGISTER-GLOBALS-REMOVED-NOTICE]
