Description:

Zend_Translate is the Zend Framework's solution for multilingual
applications.

The benefits of Zend_Translate are:
- Supports multiple source formats: Zend_Translate supports several
source formats, including those supported by PHP, and other formats
including TMX and CSV files.
- Thread-safe gettext: The gettext reader of Zend_Translate is
thread-safe. There are no problems using it in multi-threaded
environments.
- Easy and generic API: The API of Zend_Translate is very simple and
requires only a handful of functions. So it's easy to learn and easy
to maintain. All source formats are handled the same way, so if the
format of your source files change from Gettext to TMX, you only need
to change one line of code to specify the storage adapter.
- Detection of the user's standard language: The preferred language of
the user accessing the site can be detected and used by
Zend_Translate.
- Automatic source detection: Zend_Translate is capable of detecting
and integrating multiple source files and additionally detect the
locale to be used depending on directory or filenames.
