Comment (by arickrol):

 I don't know if a SVN exists for this plugin.  But, I think you, Otto42,
 are the one who made the plugin.  The author URL for the plugin is given
 as http://ottodestruct.com.

 Below is the code from the plugin.  I hope that helps.


 {{{
 <?php
 /*
 Plugin Name: Executable PHP widget
 Description: Like the Text widget, but it will take PHP code as well. Up
 to 9 instances of this widget may exist. Heavily derived from the Text
 widget code included with the widget plugin by Automattic, Inc.
 Author: Otto
 Version: 1.0
 Author URI: http://ottodestruct.com
