Source Code https://github.com/yiisoft/yii2/blob/master/framework/console/controllers/MessageController.php

Extracts messages to be translated from source files.

The extracted messages can be saved the following depending on format setting in config file:

  • PHP message source files.
  • ".po" files.
  • Database.

Usage:

  1. Create a configuration file using the 'message/config' command: yii message/config /path/to/myapp/messages/config.php
  2. Edit the created config file, adjusting it for your web application needs.
  3. Run the 'message/extract' command, using created config: yii message /path/to/myapp/messages/config.php
