 * I’m converting an existing php page to a wordpress page. On the existing page,
   I have 2 units of dynamic html based on the values of a cookie. I have existing
   code that can open / process this.
 * My question: What is the proper way to integrate custom code into a WP template.
   Do i need to make a function call for it within the worpdress umbrella, or can
   I just type my php code in the template?
 * Thanks & happy new year!

 * If using WordPress 2.0 and you prefer to separate code from design in your templates,
   you can add a functions.php file to your theme and place any custom PHP functions
   in there. WordPress will include the file automatically.
 * But hey, it’s your site, your WordPress. If the code is only to be used within
   the confines of your blog, do it however works best for you.
