Supported Languages

Hi.How to get $supportedLocales array from App class? Is it correct to get it this way :

Code:

<?php
                        $cl = new \Config\App();
                        var_dump($cl->supportedLocales);
                        ?>

PHP Code:

$config = new \Config\Language();

$array = $config->languages; 


PHP Code:

$config = new \Config\Language();

$array = $config->languages; 


No, this code returns an error. My code is working well, but is it secure or not I dont't know.
