      Currently we can go from BSON->JSON value, and PHP->BSON->JSON but not PHP->JSON.

      It seems like its not a big deal, needing the intermedied BSON format, but it is bigger deal then I first realized as people want to simply json dump their objects for APIs for example.

      echo json_encode($model);

      When $model contains ObjectID, the ObjectID will be serialized as empty.

      <?php

class Person implements JsonSerializable {
    protected $id;
    protected $name;

    function __construct($name) {
        $this->id = new MongoDB\BSON\ObjectID();
        $this->name = (string)$name;
    }

    function JsonSerialize() {
        $arr = array(
            "name" => $this->name,
            "id"   => $this->id,
        );
        return $arr;
    }
}

$p = new Person ("Jon Jonsson");

var_dump(json_encode($p));

      string(30) "{"name":"Jon Jonsson","id":{}}"

      This could have been worked around by allowing BSON\fromPHP() serialization of BSON\Type objects since they always result in a fully qualified json object, e.g.:

      { "$oid" : "56213654bd21b96c3e4e31c1" }

      So the jsonSerialize() function would become:

          function JsonSerialize() {
        $arr = array(
            "name" => $this->name,
            "id"   => $this->id,
        );

        $bson = MongoDB\BSON\fromPHP($this->id);
        $json = MongoDB\BSON\toJSON($bson);

        $arr["id"] = $json;

        return $arr;
    }

      and would result in:

      {"name":"Jon Jonsson","id":{ "$oid" : "56213746bd21b9718b1d7371" } }
