Question

I’m having trouble accessing a parent’s variable like the following:

class Priveleges
{
    protected $user_id;

    public __construct($user_id)
    {
         $this->user_id = $user_id;
    }
 }

And now my subclass:

class userInfo extends Priveleges
{

    public function __construct($user_id)
    {
         parent::__construct($user_id);
    }

    public function showID()
    {
        return $this->user_id;
    }
}


$a = new userInfo(63);
echo $a->showID();

The ouput I would expect would be 63 wouldn’t it? However, it doesn’t output anything…

Answer 1

If you instead get “unexpected __construct“, that would be because you’re missing a function here:

protected $user_id;

public __construct($user_id)
{
     $this->user_id = $user_id;
}

After fixing that, the output is indeed 63.
