Like/Dislike PHP/SQL Logic
I'm looking to code a like/dislike feature utilizing PHP/SQL (and eventually add an AJAX effect to it).

But before doing so, I'd like to know the most efficient method.

As of right now I have an sql table with my user-submitted content.
Should I add on rows "like" and "dislike" to this table? Or should I create a new table specifically for "like" and "dislike"?
