然后MongoDB找到更新 - PHP

I have a document that looks like

{
  _id: ObjectId("someId"),
  recipients: [
    {
      email: "emailaddress"
    },
    {
      email: "email2"
    }
  ]
}

I am trying to update the first recipient object, and add another property but to no avail.

{
  _id: ObjectId("someId"),
  recipients: [
    {
      email: "emailaddress",
      new_prop: "something"
    }
  ]
}

Is there a way to do this with findOneAndUpdate? I am using PHP

    I did some research. I'm new to MongoDB so I'm relying on my fellow developers to validate this code. I'm thinking this will do the trick:

    $mongoID = new MongoID('yourID');
    $newdata = array('$set' => array("recipients.0.new_prop" => "Something"));
    $collection->update(array("_id" => $mongoID), $newdata);
    

    It might help to visit this page: https://docs.mongodb.com/manual/reference/operator/update/set/
