[horde] using DB function

[Craig White]

trying to test a theory and I didn't have these kind of problems
creating connection to ldap so it's apparent to me that I am not getting
the methodology of using DB to connect to mysql...

I have this simple program...
---
<?php

$conf['sql']['phptype'] = 'mysql';
$conf['sql']['persistent'] = false;
$conf['sql']['socket'] = '/var/lib/mysql/mysql.sock';
$conf['sql']['protocol'] = 'unix';
$conf['sql']['hostspec'] = 'localhost';
$conf['sql']['username'] = 'horde';
$conf['sql']['password'] = '****';
$conf['sql']['database'] = 'horde';

require_once 'DB.php';

$_db = &DB::connect($conf['sql'], true);

$query = sprintf('SELECT pref_value FROM horde_prefs WHERE pref_uid =
"Administrator" and pref_scope = "horde" and
pref_name="category_colors"');

$result = $_db->query($query);

$values = $this->$result;

var_dump($result);
---
and it results in connection error when I know that the $conf['sql']
array is good. The top of the output is listed below.

What am I missing in this program?

Thanks
Craig
