It might help if you gave us some detail ...?

Stefan it's a class that adds two numbers together.

 

Anyway I would suggest you try this in your code;

 

$test = new inputs();

$test->$no2 = -9;
$test->addNos();

 

your class is not protected to outside manipulation, now that PHP has pretty good OOP functionality I suggest you start using the proper OOP declarations for variables, classes and functions like: public, protected, private and final.
