Hi all,

I'm starting this new project in which I'ld like to implement sort of a
design pattern I have seen being used in the CodeIgniter framework.

Basically, the site will examine the URI and based on the segments of the
URI it will fire up some controller class, for instance, say I have an inbox
in which end-users can view messages they got from other users, they'ld
start at:

http://www.somesite.com/inbox/view/

This will then call upon the function view in the class inbox:

class Inbox extends Controller
{
// ...
public function view()
{
// ...
}
// ...
}

Any trailing segments of the URI will be passed as supplement arguments to
the function.

Now, if $_POST variables are sent to some page and are needed by the called
upon function in the appropriate class, would it be bad practice to simply
extract those $_POST variables from the superglobal $_POST inside this
function? Preferably I would like to send the $_POST variables as arguments
to the function, but I'm not sure how to implement this correctly, nor am I
even completely sure as to why this would be better practice, other than
that the function will only accept predefined arguments.

What are your views on implementing such a 'pattern' (if you will). Would
you even suggest such an implementation, or am I bound to get into trouble
with proposed pattern?

Thank you in advance.
