in reply to Help understanding this script

Without all of the code and/or corresponding HTML pages, I'm going to assume that is filled in by another part of the script that we are not seeing. Basically it is used in this script to determine if you are wanting to view a specific topic or the whole topic list.

Hope this helps.

    ok so since it is $topic as the value... whatever topic is assigned later in the script that's what the value is?
      Well not necessarily "later".it could be somewhere in the code you omitted.
