Yii 1.1: pophpcommand

Message command line manager: .php <-> .po converter, message extractor and statistics.

The usual command line protected/yiic message protected/messages/config.php produces .php files whereas computer-aided translation systems such as Lokalize or PoEdit use gettext files, so I made this converter between .po and .php and added a custum extraction process to fit my needs.




  • Yii 1.1.5 or above


  • Extract the release file under protected/commands

Getting translation statistics

protected/yiic emessage statistics

You can specify the path of the configuration file (default: protected/messages/config.php). The file must be a valid PHP script which returns an array of name-value pairs.

Each name-value pair represents a configuration option. The following options must be specified:

  • sourcePath: string, root directory of all source files.
  • messagePath: string, root directory containing message translations.
  • languages: array, list of language codes that the extracted messages should be translated to. For example, array('zh_cn', 'en_au').
  • autoMerge: boolean, overwrite the .php files with the new extracted messages. Default: false.
  • launchpad: boolean, if the .po files must be stored as protected/messages/launchpad/template/lang.po or in the same directory of the converted .php file. Default: false.
  • skipUnused: boolean, do not mark unused string with '@@' and skip them. Default: false.
  • fileTypes: array, a list of file extensions (e.g. 'php', 'xml'). Only the files whose extension name can be found in this list will be processed. If empty, all files will be processed.
  • exclude: array, a list of directory and file exclusions. Each exclusion can be either a name or a path. If a file or directory name or path matches the exclusion, it will not be copied. For example, an exclusion of '.svn' will exclude all files and directories whose name is '.svn'. And an exclusion of '/a/b' will exclude file or directory 'sourcePath/a/b'.
  • translator: the name of the function for translating messages. Defaults to 'Yii::t'. This is used as a mark to find messages to be translated.

For example, my current configuration file contains:

return array(
        'sourcePath'=>dirname(__FILE__) . DIRECTORY_SEPARATOR . '..' . DIRECTORY_SEPARATOR . '..',
        'messagePath'=>dirname(__FILE__) . DIRECTORY_SEPARATOR . '..' . DIRECTORY_SEPARATOR . 'messages',
        'languages'=>array('da', 'de', 'eo', 'fr', 'it', 'nl', 'pl'),

POEdit does everything you need

If properly configured poedit can scan all files in configured paths and detect all t() strings by itself.
