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.

属性详情

$basePath public 属性

The base path for all translated messages. Defaults to '@app/messages'.

public string $basePath '@app/messages'
$fileMap public 属性

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',
]
public array $fileMap null

方法详情

getMessageFilePath() protected 方法

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

loadFallbackMessages() protected 方法 (可用自版本: 2.0.7)

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.

loadMessages() protected 方法

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.

protected array loadMessages ( $category, $language )
$category string

The message category

$language string

The target language

return array

The loaded messages. The keys are original messages, and the values are the translated messages.

loadMessagesFromFile() protected 方法

Loads the message translation for the specified language and category or returns null if file doesn't exist.

protected array|null loadMessagesFromFile ( $messageFile )
$messageFile string

Path to message file

return array|null

Array of messages or null if file not found
