# Language variables

Plugins can also use the global get\_lang() function available inside the rest of the code of Chamilo, but they have to use a variation : get\_plugin\_lang(), that requires you to give the name of the plugin in which it is used.

Language variables have to be located in a lang/\[language].php file. E.g, the basic plugin language file for plugin « abc » will reside inside the plugin's subfolder « lang »: /plugin/abc/lang/english.php

The file itself has to use the following format :

```
/* Plugin's language variables */

$strings['plugin_title'] = 'ABC';
$strings['plugin_comment'] = 'Plugin for managing the … website';
$strings['SelectASession'] = 'Select a session';
```
