I would like to include another file in the overall_header section of a phpBB style / template.
I tried the following:

As I would in a normal php script:

PHP Code:

<?php include('top.php'); ?>

and with out the php tags
include('top.php');

neither method will work.

Please advise.

PHP
A contentious decision has seen the ability to include PHP within the template introduced. This is achieved by enclosing the PHP within relevant tags:

<!-- PHP -->
echo "hello!";
<!-- ENDPHP -->
You may also include PHP from an external file using:

<!-- INCLUDEPHP somefile.php -->
it will be included and executed inline.

A note, it is very much encouraged that template designers do not include PHP. The ability to include raw PHP was introduced primarily to allow end users to include banner code, etc. without modifying multiple files (as with 2.0.x). It was not intended for general use ... hence phpBB &bull; Creating Communities Worldwide will not make available template sets which include PHP. And by default templates will have PHP disabled (the admin will need to specifically activate PHP for a template).
