This was a good question, I really had to dig into this myself to find 
out.  In fact for MapServer 6.0 there are no more clone methods, and I 
found a mention of this in this document (which is not yet public) 
http://www.mapserver.org/trunk/mapscript/php/migration_guide.html

That document contains this statement: "Cloneable objects should be 
cloned with the PHP clone keyword. There are no more clone methods."

and also:

"Class methods that have been removed:

         ...
         classObj: clone
         styleObj: clone
         mapObj: clone
"

Unfortunately this information isn't yet in the main MIGRATION_GUIDE, 
but thanks to your feedback we will make sure this is more clear.

So, in your case, you might do something like this instead for MapServer 
6.0 :

    <?php
      $map = new MapObj('blabla.map');
      $map2 = clone $map;
    ?>

Sorry for this confusion.

I don't fully understand your issue.  You might want to bring that 
question to the main MapServer-users mailing list and ask there, as I 
don't know the answer.  I don't think anything specific changed 
regarding OFFSET (I do know that MapServer 6.0 allows for label STYLE 
objects, which is described in the migration guide, but I don't think 
that is related to your question).
