Hi Leonard,
Try this:
<? php;
class first
{
var $total;
function first($age, $name)
{
$this->total = $age.$name;
}
}
//main script
$obj = new first(35, "chris");
print $obj->total;
?>
The problem with what you were doing is that when you were instantiating the class,
with the way you have set this up, you need to pass arguments because when you create
a new instance of the class the function with the same name as the class is called
and, in this case, it is expecting arguments. Another example of a class set-up would
be:
<? php;
class first
{
function first()
{
//do something like connect to a database or set some variables
}
function second($age, $name) {
/*here you could look something up in the db or do something else and
then return what ever you like*/
return $age.$name;
}
}
//main script
$obj = new first();
$test = $obj->second(35, "chris");
print $test;
?>
