* - Each PHP script is saved as a file named as `[[basePath]]/LanguageID/CategoryName.php`;
* - Within each PHP script, the message translations are returned as an array like the following:
*
* ~~~
* return array(
* 'original message 1' => 'translated message 1',
* 'original message 2' => 'translated message 2',
* );
