A simple example plugin.

<<HelloWorld salutation="Hello," name="Wiki User" >>

From the source of this page:

{{{
<<HelloWorld salutation="Hello," name="Wiki User" >>

----
~PhpWiki's plugin architecture allows you to add custom page elements to your wiki. All you have to do is extend (subclass) the ~WikiPlugin class and create your output via the run() method, dependent on the Wiki- or Request arguments,

* either with the predefined HTML classes to create valid XHTML,
* or by using templates, which are easier customizable, but generally more a mess to use and easier to create invalid XHTML.
