PHP inheriting/extending a particular instance of an Object
- by delta9
Is there any way to force PHP to extend an existing/particular (and for that matter, already instantiated) instance of an object?
This imaginary code should explain what I am wondering:
class Base
{
public $var;
function __construct($var){
$this->var = $name;
}
}
class Extender extends Base {
function __construct($parent)
{
parent = $parent;
}
}
$base = new Base('yay!');
$extender = new Extender($base);
echo 'Extended base var value: '.$extender->var.'<br/>';
Output (would be):
Extended base var value: yay!
To be clear, I am wanting to instantiate an object that extends a PARTICULAR INSTANCE of another object, one that has already been instantiated.
I am aware that I can pass a reference to an object to another object (via it's constructor function) and then add it as a property of the receiving object, I'm wondering if there is a real way to do this?
