You can be even more lazy than that.  You could just do 
if($_SESSION['var']) and it will return true / false if it's set.  It 
might throw a PHP Notice though.  I can't remember.

For good, readable code though, you should use isset.

And what does session_is_registered() do?  Sets 'global' variables?  Huh?
