That very much make sense. I am indeed doing two assignments. I was just
wondering how to call the constructor. The new statement was the only
way I saw.... and it only worked in an assignment ..... I could not call
dbaccess(); nor dbaccess::dbaccess();...
Probably the easiest way is a mix of the solutions.
Have an emtpy private constructor, and have the an init fucntion do the
work so typing does not get mixed up.
Thanks.

You made a critial error in the original implem.
You effectively write dbaccess::$db twice.
Your $dummy gets around this.
See my previous post, but the real issue is this code flow:
In GetDb() you do:
dbaccess::$db= new dbaccess();
So firstly PHP creates calls the constructor.
In the constructor of dbaccess you do:
dbaccess::$db = new mysqli(...);
So PHP will assign the mysqli object to the variable you want.
PHP will then return from the contructor of dbaccess returning the
dbaccess object itself, which is then assigned to dbaccess::$db,
overwriting the mysqli object.
Hope that explains why what you did was a bit wrong and that one of the
solutions I proposed is what you want.
