simple question

[geo353]

Ive been learning PHP for the last week and have looked at the same piece of code several times but still dont quite understand it.

Heres an example.

    class firstObject{
    	public $var1 = 'First Variable';
		public $var2 = 'Second Variable';
    }

class secondObject{
	protected $objArray = array();

	function addObj($obj) {
		$this->objArray = $obj;

	}

	function getObj(){
		return 'The ' . $this->objArray->var1 . ' and the ' . $this->objArray->var2 . '.';
	}
}

$first = new firstObject;
$sec = new secondObject;

$sec->addObj($first);
echo $sec->getObj();

The way i understand it the object is stored in an array as though its a multi dimensional array. So therefore i should be able to assign a key to each object within the array. But when i try this it doesn’t work. If someone could explain the concept here for me it would be greatly appreciated.

Many Thanks

I am not a big OO guy but I think you would need to do somthing like this:

function addObj($obj, $key) { 
   $this->objArray[$key] = $obj;           

}
