I found a solution. On the page regarding Dokuwiki integration (
http://wiki.splitbrain.org/wiki:discussion:dokuwikiintegration) there is an addition by one Esther Brunner way back in 2005. Specifically, the goal was to integrade the dokuwiki markup syntax with PHPBB. But, linked from that portion of the page was a wikiparser.php file that did what I wanted. Of course, the link on that page is no longer active, but I found it in the Internet Archive:
http://web.archive.org/web/20070522222156/http://www.qwik.ch/wikiparser.php
Hopefully, this doesn't cause any major problems for Esther, but I figured I'd like the archive snapshot here in case others find this thread.
I did encounter some errors within the code -- mostly unintialized variable notices -- and, for the moment, used the @ operator in PHP to suppress them. Also, the parser function encoded html special characters, so be aware of that in case you see & floating around for some reason. And, unfortunately, files linked from within the wiki are not linked correctly by this parser.
I'll spend some time on this -- perhaps over the weekend -- to see what I can do about the errors and the file linking issues and post more here.
