There are other good syntax highlighter plugins, but I wanted something simple and fast and 
be able to add the highlight classes with a select box in the TinyMCE editor.
I added some default languages: Javascript, PHP, Python, C, C#, VB.NET, SQL and CSS but you can 
easily add other ones.

PHPull is a WordPress plugin for developers who wish to easily and accurately reference php functions directly from the PHP.net website. The plugin is very easy to use and the tooltip display is easily customizable by updating an existing stylesheet theme or creating your own. More detailed information and examples can be found on the official plugin homepage, linked below.
Credit goes out to S.C. Chen for his Simple HTML DOM class that was used in this plugin. For more information on this class, please visit http://sourceforge.net/projects/simplehtmldom/.
Credit also goes out to Michael Leigeber for his amazingly lightweight tooltip javascript code. For more information on this class, please visit http://www.leigeber.com/2008/06/javascript-tooltip/. Michael also has a wonderful blog.
