multiple variable includes

[DrkFusion]

Thanks for replying.

I want to keep $page and $action seperate, like in Velocd tip,
on the 2nd if, it says
if $action=dostuff, then $page = '';

I think it would be easier if I put it kind of like this, how would I do 2 dynamic variable includes.

Lets pretend
I have an Information Section, Media Section, Reviews Setion, and a Main Section

so, each of them have there own variable
$information
$media
$reviews
$main

I am aiming to do this...
If $information, $media, $reviews have no value, then $main include news.html
Ex: index.php <--When nothing is specified news.html will be loaded where $main is to be invluded

but when its like..
index.php?information=info/bio.html or something similar, then bio.html will load where $inforation is in the php file, and so on.

Sorry that I am bad at explaining.

I want to do something around this line

if($action == '' && $page == '') {
  $page = "main";
}

###### page=Main ######
if($page == "main"){
include ("news.html");
}

###### Action Sent ######
if($action == "sent"){
include ("sent.html");
}
