How do I use dynamic variable inside PHP tags

Probably used wrong terminology here, sorry

The following is an include file used with HTML2PDF. It works well as it is, but I want to make things dynamic.

For instance I want to change the include template file from
/admin/pdf_template_AD_Report.php >> /admin/{{dynamic_template_filename}}.php
and also the output filename
neiltest.pdf >> {{dynamic_filename}}.pdf

but I don’t know how to format the Wappler generated value inside the PHP tags.
