Thanks a lot Lynne, init.php did the trick for me.

The posts I read mostly said to add global.php but in my case that introduced a recursive call to the header template. (which eventually crashed the browser).

Incase anyone is reading, I needed to add the following right at the top of myPHPfile.php to get things working:

define('VB_AREA', 'Forum'); 
define('THIS_SCRIPT', 'myPHPfile');

require_once("./includes/init.php");
