Hi All,
I had one php class in namespace App\Http\Lib as GISApplication which contains static data members. I want to set & access values of that static data members from different classes outside of namespace. How Can I set & access that values.

<?php
namespace App\Http\Lib; 

class GISApplication
{
public static $LOGINUSER_TYPE;
public static $USERMODULE;

// More Static Data Members

}

Suppose I want to set values of these members from LoginController class in App\Http\Controllers namespace & access that values from different classes in App\Http\Operations namespace.

Please suggest.

What I have tried:

I set values from LoginController class in App\Http\Controllers namespace AS

GISApplication::$LOGINUSER_TYPE = $auth->type;
GISApplication::$USERMODULE = $auth->module;

When I access values from FrontOperation class in App\Http\Operations AS

GISApplication::$LOGINUSER_TYPE

I will getting blank value.
