how i supplement an msaccess tie codeigniter cakephp?

i'm perplexing microsoft opening database demo digest i'm pondering doing presumably codeigniter cakephp. ignoring illusory unsteadiness controlling microsoft access, i haven't means figure out precisely tie twine corresponds frameworks' database settings. loyal php, i formula bond an opening database:

$db_connection = odbc_connect(
  "driver={microsoft opening engineer (*.mdb)}; dbq=\\path\\to\\db.mdb", 
  "adodb.connection", "", "sql_cur_use_odbc"
);

how those strings conform formula igniter db settings? doesn't seem definitely working:

$db['access']['hostname'] = "{microsoft opening engineer (*.mdb)}";
$db['access']['username'] = "adodb.connection";
$db['access']['password'] = "";
$db['access']['database'] = "\\path\\to\\db.mdb";
$db['access']['dbdriver'] = "odbc";
$db['access']['dbprefix'] = "";
$db['access']['pconnect'] = true;
$db['access']['db_debug'] = true;
$db['access']['cache_on'] = false;
$db['access']['cachedir'] = "";
$db['access']['char_set'] = "utf8";
$db['access']['dbcollat'] = "utf8_general_ci";
