MongoDB & PHP | How to add object into existing document? - php

Question

I am very new to MongoDB and PHP and I am trying to add an object into an already existing document.
The problem is that I am seeing the $push variable being used a lot, but can't seem to get it working on my own project.
My Document
{
"_id": {
"$oid": "622dfd21f8976876e162c303"
},
"name": "testuser",
"password": "1234"
}
Lets say this is a document inside my collection users. I want to add an object that is called domains with some data inside that object like below:
"domains": {
"name": "example.com"
}
I have tried a bunch of different things, but they do not seem to work.
What I tried:
I have tried doing to like this:
$doc = array(
"domains" => array("name": "nu.nl")
);
$collection->insert($doc);
And like this:
$insertOneResult = $collection->updateOne(
{"name" : "testuser"},
'$push': {"domains": {"name": "example.com"}}
);
But they both do not work.
Can anyone help me with this problem or comment a link which would help me with this problem?
Thanks in advance!

You were really close!
db.users.update({
"name": "testuser"
},
{
"$push": {
"domains": {
"name": "example.com"
}
}
})
Try it on mongoplayground.net.
I haven't used php since the ancient gforge days, but my guess at using the php connector would be (corrections welcome!):
<?php
$collection = (new MongoDB\Client)->test->users;
$updateResult = $collection->updateOne(
['name' => 'testuser'],
['$push' => ['domains' => ['name' => 'example.com']]]
);
printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
