PHP Json_encode not working with object while JsonSerializable is implemented

Question

I've got a problem. I got 2 PHP files that each echo a json_encode() of an array with objects (one an array of users and one an array of rewards). However rewards works perfectly fine while users returns [{},{},{}]

here's my users.php

<?php

header('Content-Type: application/json');

require('../logic/User.php');
require('../database/Database.php');

$database = new Database();

if(isset($_GET['id'])) {
    $user = $database->getUserById($_GET['id']);
    if($user != false){
        echo json_encode($user);
    }else{
        echo 'User not found';
    }
}else {
    $users = $database->getUsers();
    echo json_encode($users);
}
?>

And here's my User class (without magic methods):

class User implements JsonSerializable
{
    private $id;
    private $name;
    private $birthday;
    private $gender;
    private $address;
    private $postalcode;
    private $phonenr;
    private $email;
    private $facebookid;

    private $accessible = array('id', 'name', 'birthday', 'gender', 'address', 'postalcode', 'phonenr', 'email', 'facebookid');
    private $editable = array('name', 'birthday', 'gender', 'address', 'postalcode', 'phonenr', 'email', 'facebookid');
    private $required = array('id', 'name');

//getter, setter, constructor

    public function jsonSerialize(){
        return ['id' => $this->id,
            'name'=>$this->name,
            'birthday'=>$this->birthday,
            'gender'=>$this->gender,
            'address'=>$this->address,
            'postalcode'=>$this->postalcode,
            'phonenr'=>$this->phonenr,
            'email'=>$this->email,
            'facebookid'=>$this->facebookid
        ];
    }
}

$users is filled, so the problems must be the json_encode()

What are the types of private properties? If some of your properties are objects they should also implement JsonSerializable. — klipach

the properties are all strings, ints or dates (which I believe is just a string) — Sander Geraedts

Its because the user properties are private. If you make them public they will show.

However, decide if it you want to change them to public because they are probably private for a reason.
