Hi,

i would like to do something like that:

<?php
   class A extends SplInt // extends SplInt
   {
      protected $x;
      protected $y;
      public function __construct($x,$y)
      {
         $this->x = $x;
         $this->y = $y;
      }
      public function splIntMethode($other, $operator) // override SplInt-Methode
      {
         if($operator != '+')
            throw new Exception();
         if(!($other instanceof A))
            throw new Exception();

         return new A($x + $other->x, $y + $other->y);
      }
   }
   $a0 = new A(1,2);
   $a1 = new A(3,4); // $a1 is the '$other'-Objekt at methode splIntMethode
   $a2 = $a0 + $a1;  // $operator +
?>
