Wordpress syntax hiliter

I’m just trying out a nifty syntax hiliter plugin for Wordpress. This particular plugin handles HTML, CSS, PHP, Java, and SQL. I’ve modified it a little bit to suit my own personal tastes.

<?php
function hello_world()
{
echo 'hello, world!';
}
hello_world(); // tells the world 'hello'
?>

UPDATE (3 Oct 2005): I’m now using CodeHighlight.
