Class yii\i18n\PhpMessageSource
| Inheritance | yii\i18n\PhpMessageSource » yii\i18n\MessageSource » yii\base\Component » yii\base\BaseObject |

| Implements | yii\base\Configurable |
| Available since version | 2.0 |
| Source Code | https://github.com/yiisoft/yii2/blob/master/framework/i18n/PhpMessageSource.php |
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 [
'original message 1' => 'translated message 1',
'original message 2' => 'translated message 2',
];
You may use $fileMap to customize the association between category names and the file names.

Property Details
The base path for all translated messages. Defaults to '@app/messages'.
Mapping between message categories and the corresponding message file paths. The file paths are relative to $basePath. For example,
[
'core' => 'core.php',
'ext' => 'extensions.php',
]
Method Details
Returns message file path for the specified language and category.
| protected string getMessageFilePath ( $category, $language ) | ||
| $category | string | The message category |
| $language | string | The target language |
| return | string | Path to message file |
|---|---|---|
The method is normally called by loadMessages() to load the fallback messages for the language.
Method tries to load the $category messages for the $fallbackLanguage and adds them to the $messages array.
| protected array loadFallbackMessages ( $category, $fallbackLanguage, $messages, $originalMessageFile ) | ||
| $category | string | The message category |
| $fallbackLanguage | string | The target fallback language |
| $messages | array | The array of previously loaded translation messages. The keys are original messages, and the values are the translated messages. |
| $originalMessageFile | string | The path to the file with messages. Used to log an error message in case when no translations were found. |
| return | array | The loaded messages. The keys are original messages, and the values are the translated messages. |
|---|---|---|
Loads the message translation for the specified $language and $category.
If translation for specific locale code such as en-US isn't found it
tries more generic en. When both are present, the en-US messages will be merged
over en. See loadFallbackMessages() for details.
If the $language is less specific than $sourceLanguage, the method will try to
load the messages for $sourceLanguage. For example: $sourceLanguage is en-GB,
$language is en. The method will load the messages for en and merge them over en-GB.

| $messageFile | string | Path to message file |
| return | array|null | Array of messages or null if file not found |
