internationalization - What are good tools/frameworks for i18n of a php codebase?

Question

I have been looking at a few options for enabling localization and internationalization of a dynamic php application. There appears to be a variety of tools available such as gettext and Yahoo's R3 and I am interested in hearing from both developers and translators about which tools are good to use and what functionality is important in easing the task of implementation and translation.

Answer 1

PHP gettext implementation works very smoothly. And po files with po edit and gettext are about as good a way as you can get to deal with localization bearing in mind that no solution of this kind can completely handle the complexities of the various languages. For example, the gettext method is very good on plural forms, but nothing I've seen can handle things like conjugation.
