You can use the data: URL scheme; this embeds the data directly within
the HTML. However, the size of the encoded image (including header) is
limited to 1024 characters, so you can't put large things into it.
The other way to do that is to wrap the PHP function as a CGI script in
the pub/ directory. You'd then have
The PHP can then pick the parameter value from $_REQUEST['parameter'].
(Note that you are responsible for doing any access checks from within
the script if you want to do it that way.)
