TikiWiki or similar with php 4

I'm lookin开发者_运维百科g for content management system/framework to build a website which has some (more or less) static pages, an events calendar and a wiki section, possible adding a forum at some point. The best I've found is TikiWiki, but my host (which I can't change) is still using php 4. Anyone have any other suggestions? I'm not bothered about general site design/themes (in fact I'd prefer to do that myself), just something to manage the back end. Been thinking about writing it myself, maybe using something like codeigniter, or cobbling together a couple of different cms's, but I'm open to suggestions.

Old releases of DokuWiki (<= 2009-02-14b) work with PHP 4. There are many plugins for DokuWiki that may implement the functionality and writing your own plugins is a snap.

Drupal 6 may also be a good option.

Be prepared for lots and lots of errors, cursing and backporting work when using plugins. PHP 4 is officially "dead" for two years now.
