Include php in skins

[apeitup]

I am trying to add/include a php file that contains my header and my access control system. How do I deal with php within a skin template.

The path to the file would ordinarily be and I would then just call it with the normal but this does not work within the theme templates.

I have had a  look around and do not seem to be able to find the solution for this any assistance would be greatly appreciated.

Thankyou

In /config/main.inc.php set $rcmail_config['skin_include_php'] to true.

Yeah I did try that but they are still being conditioned out like so  "". I will have to dig a bit further I am sure I have just missed something.
