still not working: why?

[vinnie]

hi guys, i'm just at the beginning. I apologize. the file still gives
me back an error:

<<Parse error: syntax error, unexpected T_VARIABLE, expecting
T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in d:\tryphp.php on line
19>>

why? Can someone fix it so i can "study" the working one?

class somma
{
var $uno=10;
var $due=15;
var $tre=15;
function sum($uno,
$due, $tre)
{

$totale = $uno + $due + $tre;

return($totale);
}
function sum_2()
{
$totale = $this->sum($this->uno, $this-

>due, $this->tre);

return $totale;
print("$totale");
}
$somma=new_somma();
$sum=$somma->(34,40);
print("$sum");
}

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.

Vinnie, are you sure this isn't homework (again!) ? Your first msg clearly
stated:

please help me, i have a test!

I cannot help but think you hardly have a clue about PHP's syntax and
semantics. If you read the replies carefully the answer is already there,
but it seems you just want us to deliver the working code for you.

Sorry, no can do.

Hi Vinnie,

Why do you first return something, and then print something on the next
line?
What do you think will happen?
Will the print-statement ever be reached?

}
$somma=new_somma();

}

but also if i try to echo $sum, i get nothing, so there must be a
mistake somewhere, and using the 2 books i have it's hard to find
(PHP5 for dummies, and core PHP programming).

First of all, turn on all errors in your php.ini file and display them:

error_reporting = E_ALL
display_errors = On

So you can see your errors. That should help you a little bit.
