I'm currently migrating a web application from a database-based internationalization approach (each word having an entry in the translation table, and the actual translation) to one based on Zend_Translate and CSV files.
I need to provide a end-user friendly way to update those translations quickly and easily. Ideally, to minimize the risk of breaking stuff, users would not edit the CSV files directly, but be shown a nice form with fields.
Do you know a standalone, PHP-based, end-user compatible translation frontend that supports one of the adapters Zend_Translate has to offer - ideally gettext or csv?
Something like Python's/Django's Rosetta but in PHP? Rosetta does exactly what I need:
but I would very much like to stay with PHP here for server setup reasons.
SimplePO looks like it goes in the right direction, but is too simple - it doesn't seem to be able to handle multiple languages and catalogs, and plurals.
