title: PHP Can static:: replace self::?
body: <p>I am a little confused with this matter. I am designing an ORM class that tries to behave very similarly to ActiveRecord in ruby on rails, but that's beside the point.</p>
  
  <p>What I'm trying to say is that my class makes extensive use of static attribute inheritance, specially for database and table handling. My question is, should I use self:: at all?</p>
