access var outside class

[Gasolene]

is it possible to access a var from a container class without passing the var or using globals??

ie:

class foo
{
  function foo()
  {
    // i want a reference to bar->stuff;
    // is it possible using some sort of scope resolution operator to access?

// i woul like to do something like this
bar::stuff->render();    
  }
}

class bar
{
  var $obj;
  var $stuff;

  function bar()
  {
    // create instance of someobject inside bar
    $this->stuff = new someobject;

// create instance of foo inside bar
$this->obj = new foo;
  }
}

problem solved

class BaseClass
{
	var $SomeProperty;
	var $BaseClass;

	function BaseClass()
	{
		$this->BaseClass =& BassClass::Self();
	}

	function & Self()
	{
		static $instance;
		if (is_null($instance))
		{
			$instance = $this;
		}
		return $instance;
	}
}

class Object extends BaseClass
{
	function Object ()
	{
		parent::BaseClass();
		$this->BaseClass->SomeProperty=15;
	}
}

class AnotherObj extends BaseClass
{
	function AnotherObj()
	{
		parent::BaseClass();
		echo $this->BaseClass->SomeProperty; // outout: 15
	}
}

In your second example, the two subclasses are children of BaseClass and so have access to $SomeProperty by default. Why bother with the static variable? There could be a good reason I'm just curious.

Edit: I think you need access to the object rather than the class - correct? If you didn't know this is the Singleton pattern in action 🙂

with the static variable, evertime an instance of any baseclass or derived class is created, a reference to the 'same' instance is made.

this allows me to access the same data regardless of where i am in the app.

i got the idea from phpPatterns.com and modified me baseclass to create a static reference to itself so any instance of that object could access the same properties.
