WordPress.org

This plugin allows plugging HTML or a result of evaluating PHP code as a footer after the post body in the single post display window. This is very useful when e.g. adding Google Ads to your blog. The HTML fragment is added enclosed in a DIV HTML element. You can also specify PHP code to use. The code is then passed to eval() and the result of eval() is enclosed inside a DIV HTML element.

There is a configuration page (under Settings) that allows specifying the fragment and whether it's PHP or HTML.
