It may throw some E_STRICT errors warning of things that will be deprecated in a later major PHP release. I doubt DokuWiki needs register_globals, and magic_quotes shouldn't be a question. Use the strict level warnings as hints to help you find what needs to be modified in your own code. Travis Doherty
