PHP code in wordpress posts?

Hey guys.

I’ve been looking at having dynamic content on a single wordpress post, and I was wondering if it’s possible to include php code. I’ve disabled the WYSIWYG editor and the RTE editor, but my php tags still get stripped out when I post.

I’ve spoken to someone else, and he mentions that I can stop my posts being filtered by editing kses.php, but I’m not sure which parts of that file to change.

Any ideas?
