23. Internationalization
CodeIgniter
The language class in CodeIgniter provides an easy way to support multiple languages
for internationalization. To some extent, we can use different language files to display
text in many different languages.
We can put different language files in application/language directory. System language
files can be found at system/language directory, but to add your own language to your
application, you should create a separate folder for each language in
application/language directory.
Creating Language files
To create a language file, you must end it with _lang.php. For example, you want to
create a language file for French language, then you must save it with
french_lang.php. Within this file you can store all your language texts in key, value
combination in $lang array as shown below.
$lang[‘key’] = ‘val’;
Loading Language file
To use any of the language in your application, you must first load the file of that
particular language to retrieve various texts stored in that file. You can use the following
code to load the language file.
$this->lang->load('filename', 'language');
filename – It is the name of file you want to load. Don’t use extension of file
here but only name of file.
Language – It is the language set containing it.
Fetching Language Text
To fetch a line from the language file simply execute the following code.
$this->lang->line('language_key');
Where language_key is the key parameter used to fetch value of the key in the loaded
language file.
Autoload Languages
If you need some language globally, then you can autoload it in
application/config/autoload.php file as shown below.
