Would it be possible to initialize a protected SplObjectStorage as a map within a class? I seem to be running into an error whenever I try this. Similar to example below: 

class a {

  protected $a = new SplObjectStorage();

  ...

}

    You can only initialise a class property with a simple type or an array. It would be great to be able to do what you want, but this is another one of PHP's artificial limitations – Bojangles Jun 08 '14 at 22:09

    You will have to initialize that inside the constructor. – Jon Jun 08 '14 at 22:09
  • You can't do this, but you may wish to consider injecting the inner instance into the outer one, so that it is not hard-wired. – halfer Jun 08 '14 at 22:48

you need to use constructor

class a {
  public function __construct() {
     $this->a = new SplObjectStorage();
  }

  protected $a;

  ...
}
