I have an object which stores an app configuration in an associative array, as this:[  'Database' =>     [      'DB_SERVER' => 'localhost'      'DB_NAME' => 'adbname'      'DB_USER' => 'theuser'      'DB_PASS' => 'thepass'    ]]And a function, get(), which receives a variable number of arguments and returns the configuration value for this parameters. For example, Config::get('Database','DB_PASS') will return 'thepass'. This is an excerpt of the code:class Config{    protected static $values;    ...    public static function get()    {        $val = &self::$values;        $argList = func_get_args();        for ($i = 0; $i < count($argList); $i++) {            $val = &$val[$argList[$i]];            if(empty($val)) break;        }        return (is_null($val)?:$val);    }}Is there a more elegant / efficient way of accessing the value?
