MongoDB\BSON\ObjectID Lost In JSON Encode from MongoDB

I am having a problem where I retrieving an ObjectID from a MongoDB database , but the '_id' value is always disappearing when ran though json_encode. All the other data in my array is present. My code is as such:

$data = array('_id' => new MongoDB\BSON\ObjectID(), 'title' => 'abc123');

 //ID Is there!
 print_r($data);
 //ID IS EMPTTYy!!!
 print_r(json_encode($data));
 exit();

The results look like this:

Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 56d9d2687e34d70d3a304c46 ) [title] => abc123 ) 

{"_id":{},"title":"abc123"}

At the very least, the _id should have an object or number in it. My question is what is stripping out the \MongoDB\BSON\ObjectID and how can I get it to stay?

example code for @malarzm's answer:

$output = [];
foreach( $data as $key => $val){
    $val->_id = strval($val->_id);
    $output[$key] = $val;
}

echo json_encode( $output );

My question is what is stripping out the \MongoDB\BSON\ObjectID

json_encode will encode only public properties of encountered objects.

how can I get it to stay?

You could cast it to string before encoding.
