Tanks for your response, but your solution do not work for me, because I =

don=92t get the resource_id as parameter for calls to the object.=20
($php_url_object->set_string(=93asdf=94); )
I now save the C++ Object pointer in a resource and save this resource=20
as an attribute of the PHP object.

PHP_FUNCTION(url_init)
{
	Url_class * url =3D new Url_class;
	zval * this_p =3D getThis();
	MAKE_STD_ZVAL(return_value);
	int res_id =3D ZEND_REGISTER_RESOURCE(NULL, url, le_url);
	add_property_resource(getThis(), "url_class_ressource", res_id);
}

It=92s a little bit tricky to extract this resource and the inherit=20
pointer again, like I do in my set_string function:
PHP_FUNCTION(url_set_string)
{
	zval ** ressource;
	if( zend_hash_find(getThis()->value.obj.properties,
		"url_class_ressource", sizeof("url_class_ressource"),
		(void**) &ressource) =3D=3D FAILURE )
	{
		php_error_docref(NULL TSRMLS_CC, E_WARNING,
			"Could not find url_class_ressource");
		RETURN_FALSE;
	}

	if( ressource =3D=3D NULL || (*ressource) =3D=3D NULL
		||(*ressource)->type !=3D IS_RESOURCE )
	{
		php_error_docref(NULL TSRMLS_CC, E_WARNING,
			"Ressource not found");
		RETURN_FALSE;
	}

	Url_class * url;
	url =3D (Url_class *) zend_fetch_resource(ressource TSRMLS_CC, -1,
		"url", NULL, 1, le_url);
	ZEND_VERIFY_RESOURCE(url);

	if( url =3D=3D NULL ) {
		php_error_docref(NULL TSRMLS_CC, E_WARNING,
			"Ressource is invalid???");
		RETURN_FALSE;
	}

	if(url->setString("test")) {
		RETURN_TRUE;
	}

	RETURN_FALSE;
}

But I don=92t get memory leeks, because php makes sure my resource is=20
destructed if it is not referenced anymore:
static ZEND_RSRC_DTOR_FUNC(destroy_url)
{
	Url_class * url =3D (Url_class *) rsrc->ptr;;
	delete url;
}

I am not to happy with this solution, because the user can access the=20
"url_class_ressource" attribute of the PHP url Object, but this will=20
work for now.
Or can someone give me better solution? I am happy for everything which=20
may help me,=85
