i didn't put in different views folders....

just did that:

application/views/hello_view.php

Code:

<h1>&lt;?=$this->lang->line('hello_title');?&gt;</h1>

<p>&lt;?=$this->lang->line('hello_text');?&gt;</p>

application/language/pt-br/app_lang.php

Code:

$lang['hello_title'] = 'Olá Mundo';
$lang['hello_title'] = 'Esta é uma aplicação padrão, só pra teste';

application/language/en/app_lang.php

Code:

$lang['hello_title'] = 'Hello World';
$lang['hello_title'] = 'Just testing application, don t worry!';
