When I call a method that initializes a instance variable that isn't declared, php doen's complain. I see this as a bug, because when I mis-spelled an instance variabele some strange things happen. Because when I trie to get the value of an instance variabele, I get the old/unitialized value.

Here is some sample code:

<?

class apple
{
   var $color;

   function fruit($new_color) {
      $this->color = $new_color;
   }

   function set_taste($new_taste) {
      $this->taste = $new_taste;
   }
}

$green_apple = new apple('green');

$green_apple->set_taste('good');

?>

Not a bug at all, you don't need to declare any variable in PHP, nowhere. Adding an error for this will break tons of scripts, so we're not going to add it.
