CodeIgniter本地数据库连接问题

I have tried this to make local database connection. But it gives this error:

You have specified an invalid database connection group (ci_test) in your config/database.php file.

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',  // pass this
    'username' => 'root',  // pass this
    'password' => '',  // pass this
    'database' => 'ci_test',  // pass this
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => TRUE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array());

    This error relates to the connection group, not the database name. The connection group you have specified there is default, as shown on the first line: $db['default'].

    Look for:

    $active_group = 'ci_test';
    

    Replace it with:

    $active_group = 'default';
    

    There is more information in the codeigniter documentation.
