How to include header and footer of the forum?

[soccerclue]

All right. I have a problem here to make the header and footer. If I call the template which has the html code inside, the header and footer can be displayed but the content of the php page is not displayed. In fact, in my php page, I have also included the html stuff. What I fail is calling the $header, $footer, and $headinclude variable. If I don't want to create template, how should I call these variables in my php page? Hope you understand what I mean.

Is it something like this to call the variable?

eval("\$header = \"".gettemplate('header')."\";");
