declaring a object inside a class, giving some weird warning

Question

I am trying to declare an object of type Spell in my class Game like this:

<?php
require 'Spell.php';

class Game
{

    public $Name;
    public $Spell;

    function Game()
    {
        $Name[0] = 0;
        $Spell = new Spell;

    }

This is returning this warning:

"Warning: Creating default object from empty value in"

and I'm not sure why.

Answer 1

You should use

function Game()
{
    $this->Name = [ 0 ];
    $this->Spell = new Spell();
}

Try the following:

class Game
{

    public $Name = array();
    public $Spell;

    function Game()
    {
        $this->Name[0] = 0;
        $this->Spell = new Spell();

    }
}
