I'd like alinks to process a php tag in a link

I would like for Alinks to process the php tags I need to add onto some of my links in order to track the keywords a visitor used to come to my site.

For example, I have a tracking program that uses PHP. the links I create look something like this:
http://www.otherdomain.com?foo=<?php echo $var; ?>&glid=123456789

*where 'foo' equals some variable like 'keyword' or 'trackID' or 'tid' or 'sub-id', etc ad nauseum...
*where 'glid'' equals my google conversion tracking ID

So, I'd like to configure alinks to automatically link "my cool keyphrase" to a URL and add one or more variables onto the end of it, and include a PHP tag within those variables.
