Codeigniter PHP: Error when load config database in controller?

Question

I have got error "Your application/config/database.php file does not appear to contain a valid configuration array." when load config database in codeigniter:

Here my controller:

$this->config->load('database');

Here my file database.php:

$active_group = 'default';
$active_record = TRUE;
$tnsname = '(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
        (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl)))';
$db['default']['hostname'] = $tnsname;
$db['default']['username'] = 'system';
$db['default']['password'] = 'xxxxxx';
$db['default']['database'] = '';
$db['default']['dbdriver'] = 'oci8';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

I load config file database and I want to change config database from controller? will know how to do that?

请在database.php中指定数据库名称（对于$db['default']['database'] ），并在控制器中提及您在设置的$this->config->load('database_name')配置文件
