I have a PHP website backed by a MySQL database and a small team of programmers submitting code to subversion. Typically we write code, test it locally, commit to subversio
The export can be automatically done after every commit with a post-commit hook:
http://svnbook.red-bean.com/en/1.5/svn.ref.reposhooks.post-commit.html
You can setup the hook to automatically export the project inside the hidden area for the online testing.
