complex link code

Hi everyone, i need someone to PLEASE tell me what’s the php code for getting a variable and putting it inside it’s link.
Let me explain…

i created a custom taxonomy and it’s going to be showing the taxonomies on the catalog items i have created. But i need these taxonomies to have a link to themselves. For example:
If the author is john i want pleople to go to https://www.mysite.com/john when they click on it; and if the author is paul, i want them to to go https://www.mysite.com/paul do you know what i mean?

I know this is possible because it’s grabbing the text displayed on that spot and putting it inside the link code, i just don’t know php and i don’t know how to do it.

SOMEONE PLEASE HELP ME.

Thanks
