please help with references

I solved it but thanks...

for those who might be interested (the correct function):

function EngineClass(&$engine){
$this->engine=&$engine;
}

Hi all, please take a look at this code and tell me why it is not working...

what I try to do here is to make an Engine, and I want to pass a reference of it to all objects created in Engine.
I included the output also, and as you can see instead of what I want (pass the reference of Engine to all classes), the classes get a copy of the current Engine class... but why ??????????? please help !!!

class Engine{
	var $wannaLog=false;
	var $logger=false;

	function main(){
		$this->wannaLog=new WannaLog($this);
		$this->logger=new Logger($this);
		$this->wannaLog->doit();
	}
}


class EngineClass{
	var $engine=false;

	function EngineClass(&$engine){
		$this->engine=$engine;
	}

	function logEngine($msg){
		if(is_object($this->engine->logger)){
			$this->engine->logger->logEngine(get_class($this) . $msg);
		}
	}
}


class Logger extends EngineClass{
	function logEngine($msg){
		echo $msg;
	}
}

class WannaLog extends EngineClass{
	function doit(){
		$this->logEngine("wanna log");
	}
}

$engine=new Engine();
$engine->main();

echo "<pre>\n\n";
echo var_dump($engine);
echo "</pre>\n\n";

OUTPUT:

object(engine)(2) {
["wannaLog"]=>
&object(wannalog)(1) {
["engine"]=>
object(engine)(2) {
["wannaLog"]=>
bool(false)
["logger"]=>
bool(false)
}
}
["logger"]=>
object(logger)(1) {
["engine"]=>
object(engine)(2) {
["wannaLog"]=>
object(wannalog)(1) {
["engine"]=>
object(engine)(2) {
["wannaLog"]=>
bool(false)
["logger"]=>
bool(false)
}
}
["logger"]=>
bool(false)
}
}
}
