php - Initiate CDbConnection with full set of parameters -

i need initiate (next default one) database connection , want same way, yii configuration. i.e. feed configuration array:

array (     'connectionstring'=>'mysql:host=localhost;dbname=dbname',     'charset'=>'utf8',     'username'=>'username',     'password'=>'password',     'emulateprepare'=>true ) 

and sure, all cdbconnection's properties correctly set.

but, cdbconnection::__construct accepts $dns, $username, $password , nothing else.

the way, found far, initiate cdbconnection empty values , iterate through configuration array keys , set each each:

$db = new cdbconnection();  foreach($config $key->$value) {     $db->$key = $value; }  $db->active = true; 

but, have feeling, there should better way of doing this.
