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'
    ]
]

It could have more than two levels.

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?

(note: I posted the question here but I was notified this web was a proper place to ask)
