使用PHP更新MongoDB嵌套数组元素

Question

我正在使用MongoDB和PHP，使用Mongo元素结构：

{
    "_id": {
        "$oid": "5b123457848393"
    },
    "userName": "Bob Dole",
    "userID": "ab9283829a",
    "lastLogin": "1527873728",
    "photos": [
        {
            "fileName": "IMG_001.jpg"
        },
        {
            "fileName": "IMG_002.jpg"
        },
        {
            "fileName": "IMG_003.mp4"
        },
        {
            "fileName": "IMG_004.jpg"
        }
    ]
}

理想情况下，我想利用 userID 和 fileName 属性来更新 photos 数组中的条目，添加新的元数据不存在。例如，我希望我的更新条目看起来像这样;

{
    "_id": {
        "$oid": "5b123457848393"
    },
    "userName": "Bob Dole",
    "userID": "ab9283829a",
    "lastLogin": "1527873728",
    "photos": [
        {
            "fileName": "IMG_001.jpg",
            "cameraType": "Canon",
            "cameraModel": "5D"
        },
        {
            "fileName": "IMG_002.jpg"
        },
        {
            "fileName": "IMG_003.mp4"
        },
        {
            "fileName": "IMG_004.jpg"
        }
    ]
}

尽管我付出了最大的努力，但我未能确定如何更新只是用户ID为ab9283829a且fileName为IMG_001.jpg的条目。我的尝试;

$updateResult = $collection->updateOne(
   ["eventID" => "ab9283829a"],
      ['$set' => ["photos" => ["photo" => "IMG_001.jpg", "cameraType" => "Canon", "cameraModel" => "5D"]]]
);
