|------------------------------------------------------------------------
| Code Igniter Language Detect Library
|
| Functionality: determine user's language from the browser's language
| preference settings and store its ISO code in the configuration entry
| 'lang_selected'.
| The directory of the language files for the CI Language class is stored
| in the standard CI configuration entry 'language'.
|
| This class reads the following configuration entries:
| $config['avail_lang'] = array(
| 'en' => 'english',
| 'en_us' => 'english',
| 'de' => 'german',
| 'es' => 'spanish'
| );
| $config['lang_default'] = 'en';
| $config['lang_selected'] = 'en';
|
| Full language codes such as en_uk, de_at are supported. If there is no
| configuration entry for them, their base language, i.e. en, de, etc. is used.
| If no match was found, the configured default language is taken.
|
| The selected ISO language code is included as URI segment in all links that
| are generated by the site_url function of the MY_Config class. Additionally
| a cookie is set that stores the selected code for a longer time period.
| The cookie can be configured by the following configuration values (all
| other cookie parameters are taken from the standard CodeIgniter
| configuration items):
| $config['lang_cookie_name'] = 'xxx_language';
| $config['lang_expiration'] = 63072000; // 2 years
