You didn't tell what function to call.
When you create an object, you create something with both properties and
methods. You interact with the properties through the methods.
In this case you're not really using any of the properties of the class
($uno, $due, $tre). Rather, you're just trying to call a function with
some parameters.
OOP is a very different way of thinking, but (IMHO) a much superior way
of programming.
For instance, in your class, you might want functions to set
$somma->uno, $somma->dup and $somma->tre, then have a function which
would add the three. While not particularly useful in this instance, it
would be a more accurate example of OOP.
