I have recently had great success installing dokuwiki and setting up my own template. The best comparison I have give this experience is the one I had with dovecot. For this I am very thankful.
I would like to allow my pages to do things where normal php would be able to. For example, at
http://myx0m0p.110mb.com/screenparser.php you can have an example of a page that will have a form and call itself and display on a new page the results.
Another thing I want to do is host a game that I am developing that would use some ajax. For this, it is probably simple enough to just integrate the php in the page.
I hope that I am being clear enough on what I would like. I believe that some kind of plugin may provide some of the behaviour I am looking for, but the documentation is not the easiest for me to follow on the making of a plugin.
