Php code question

Hello

I am using a php contact form in my site and the processing code sits at the top of the page before the <doctype html> as below.

I would like to allow my client to edit a couple of items in the php code through perch.

The code does not work used with place in the code-block.html and can I use php template functions n php code? Is this possible at all?

My code is here and I want the client to be able to edit the email addresses.

<?php include('../perch/runtime.php'); ?>
