someone please alter this snippet just a bit so it would be a correct test
script with a call to it?
When I run the script I get this
Apparently it does not like the function name to be the same as the class
name. So change one of them.

class first
{
var $age;
var $name;
function first($age, $name)

No, what's happening is that when you instantiate an class, it runs
(as a constructor) the function whose name is the same as the class.
So when you do this:

Is useless ;-) I think you wanted this:
function setData( $age, $name )
{
$this-age = $age;
function setData( $age, $name )
{
$age = $age;
