php Object Class Error: Creating default object from empty value

Question

I get the following error Creating default object from empty value... each time I attempt to add a nested object.

class api {

    private $authentication=null;
    private $status=null;
    private $response=null;

    public function __construct($user, $token) {
        $this->status->version=2.3; 
        $this->authentication->user=$user;
        $this->authentication->token=$token;
    }

}

How can I accomplish this exact thing without getting this error?

I don't want to use arrays for this particular thing.

does this help you or am I misunderstanding...

public function __construct($user, $token) {
    $this->status = new stdClass(); // Here
    $this->status->version=2.3; 
    $this->authentication = new stdClass(); // & Here
    $this->authentication->user=$user;
    $this->authentication->token=$token;
}

OK, my bad. Updated, but does it work? – Simon K Jul 15 '18 at 02:27
Yes it does work. Thanks. But can you explain why I have to do this? – Nikk Jul 15 '18 at 02:31
My understanding here is that `$this->status` and `$this->authentication` are set to null (not an object) so you have to cast them to an object first before assigning properties to them. – Simon K Jul 15 '18 at 02:39
How would I cast them to objects? – Nikk Jul 15 '18 at 02:56
Just handle it in the constructor as per my answer for convenience. – Simon K Jul 15 '18 at 02:58
