如何在config中访问语言文件？

How we can use language file inside config.php php codeigniter? I searched to find solution just from out side the config we can set item in config to use language file for setting config item value, but how we can set config item using language file inside config file? for example i want to do as bellow:

$config['item'] = array(
    '1' => $ci->lang->line('my_name')
);

You use wrong way. You try make view function in config file. You can make this in template or may be in model.

You should change your application architecture.

you can't access ci object in config file because this is load before CI_Loader class. but you can update config.php field later on run time, using $this->config->set_item('key', 'value'); function in controller/model/library

sample code in controller __construct(){} method

public function __construct(){
  $this->config->set_item('item', array('1' => $this->lang->line('my_name')));
}

Another way use hooks to update item globally, more detail available on CI documentation.
