I'm looking fo开发者_开发技巧r a PHP script to build Collaborative translation site where multiple users, can translate words/sentences and view/edit or add their comments on translations (like Launchpad translation system)..

is there anything like this ?

thanks.

Although it's not tailored to your specific need, an approach that would work is to set up a wiki site. You can get wikipedia's php code here or a google search will show dozens of other options.

Launchpad itself is open source.
