var should not be used, it's a PHP4 convention and has been obsolete since PHP5 was released. It's mapped as an alias to public and still works only for backwards compatibility reasons. New code should use either public, private, or protected to declare the variables, which ever is appropriate for that variable.


class Klass { 
   public $aPublicVar;
   protected $aProtectedVar;
   private $aPrivateVar;
