Help with URL Parameter Plugin

I am using https://www.ads-software.com/extend/plugins/url-params plugin to grab URL parameters. It is working when URL is like this : https://www.somedomain.com/ but not working when the URL have intenal anchor link like this: https://www.somedomain.com/#link.

When I had seen the code it appear it is using regular expressing to parse the Parameters. What changes I need to do to this code in order to accomplish my requirement of parsing the URL parameters in both the situations?

$params = preg_split('/\,\s*/',$atts['param']);
