[PHP] Re: oop problems code
Orlando,
Displayer also inherits the constructor from Employee, so you must
define function Displayer() to prevent the notices.
I don't think you want to extend from Employee with Displayer - it
should accept an Employee object, and display the information, perhaps.
Regards,
Greg

I don't know what happen in this code, because, the last inheritance
(Displayer Class) that I made, it is inherited the properties and
methods of the Employee Class, and as Employee Class is also inherited
the functionality of the parent class, the Displayer Class would be
inherit this functionality, too.
thanks if any could help me, regards, bye.

well, actually you don't have to declare them, you can add members as you go
(as opposed to C++ for example)
class ctest
{
var $owner;
function ctest($owner)
{
$this-owner = $owner;
}
function foo()
{
echo test!br;
}
}
