* PhpMessageSource represents a message source that stores translated messages in PHP scripts. |

|
* PhpMessageSource uses PHP arrays to keep message translations. |
|
* |
|
* - Each PHP script contains one array which stores the message translations in one particular |
|
* language and for a single message category; |
|
* - 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', |
|
* ); |
