OO PHP Accessing public variable from another class

Question

I have a class like the following:

class game {

    public $db;
    public $check;
    public $lang;

    public function __construct() {

        $this->che         


        

Answer 1

you can make it static variable, so you will be able to call it anytime anywhere, the diff is that instead of

$this->lang;

when editing it(Works inside class game only) you do :

self::$lang;

and when you call/edit it (Works everywhere) from anther class you do :

game::$lang

the idea of static class is that its exist only in one instance, so only one $lang exist in your program. but there is no need to load the whole class to get acsess to it.
