                'actions'=>array('update'),
                'expression'=>'$user->id==$owner_id',
));
}

Answer 1

It's very hard to tell what you're trying to do or what the problem is, but I would use "{}" and double quotes rather than single quotes when building your array so that your variables are interpreted correctly:

public function accessRules(){
$owner_id = $this->loadModel()->owner_id;
return array(
...
        array('allow', 
                'actions'=>array('update'),
                'expression'=>"{$user->id}=={$owner_id}",
));
}

Answer 2

You can use

 array('allow',
            'actions'=>array('update'),
            'users'=>array(Yii::app()->user->name),
            'expression' => '(Yii::app()->user->id == ($_GET[\'id\']))',
                    ),
