PHP or Javascript Links for website

Here are the facts on this project.. I have links on my pages in this format.. [login to view URL] At the location "abcdefg" presently I have an [login to view URL] file. What I want is this.. I want the directory name of "abcdefg" to be included in another link that is actually my affiliate link to things in [login to view URL] like this... [login to view URL] But, the user can only see the link "[login to view URL]" I can place all of the directories in a text/word/excel file, or we can create a Mysql database. Your choice. I am leery of Javascript, but if a user doesn't have javascript turned on they wouldn't be able to use the website anyway, so Javascript would be OK. I prefer to use PHP for simplicity if possible. BTW. The [login to view URL] files can easily be renamed to [login to view URL] if necessary.
