在Codeigniter Mongo類中切換數據庫

Question

我正在使用codeigniter mongo類。我將配置信息（如mongohost，mongodb名稱等）存儲在codeigniter中的config/mongo.php中。但是，我想在我的代碼中的某些地方切換db名稱，而不必每次都重新編寫config/mongo.php。是否有開關數據庫功能或任何其他方式？

You can set another in the config aside from your default one：

// your code 
$this->load->database('test'); 

// config 
$db['test']['hostname'] = "localhost"; 
$db['test']['username'] = "root"; 
$db['test']['password'] = ""; 
$db['test']['database'] = "database_name"; 
$db['test']['dbdriver'] = "mysql"; 
$db['test']['dbprefix'] = ""; 
$db['test']['pconnect'] = TRUE; 
$db['test']['db_debug'] = FALSE; 
$db['test']['cache_on'] = FALSE; 
$db['test']['cachedir'] = ""; 
$db['test']['char_set'] = "utf8"; 
$db['test']['dbcollat'] = "utf8_general_ci"; 
$db['test']['swap_pre'] = ""; 
$db['test']['autoinit'] = TRUE; 
$db['test']['stricton'] = FALSE;
