更新嵌套数组mongoDB PHP

Question

i actually have a issue with mongodb im trying to update/add a value in a nested array.

{
    "_id" : ObjectId("56c37e98aff662100900002a"),
    "name" : "michell",
    "game" : [{
        "name" : "GTA",
        "badges" : [{
            "name" : "pacifist"
        }, {
            "name" : "killemall"
        }]
    }]
}

you can find below the way i tried but actually it just rewrite the badges array of create new game array

 $collection->update(array('_id' =>new MongoId($id),'jeux.name'=>$name), array('$set' => array('jeux'=>array('name' => $name,'badges'=>array('name'=>$badge)))));

i can't find the issue here if you could help me
