How To Use Multiple Switches From Url Variables?

[astralkid]

How would I use multiple switches in a page that would get its cases from url variables?

ie: [/i]www.site.com/index.php?page=x&sub=y&act=z[/i]

 

<?php
switch ($page) {
 case 'x': include('page.php'); break;
 case 'x2': include('page2.php'); break;
 default: code; break;
}
switch ($sub) {
 case 'x': include('sub.php'); break;
 case 'x2': include('sub2.php'); break;
 default: code; break;
}

switch ($act) {
 case 'x': include('act.php'); break;
 case 'x2': include('act2.php'); break;
 default: code; break;
}
?>

 

I'm curious as to how if i was to use:

index.php?page=admin&sub=blog&act=edit_post

 

...as to how I would be able to use switches via the admin.php/blog.php pages. From admin.php, I have the following in a switch:

-blog manager

-files manager

-photo gallery

-quotes manager

and inside these pages I have "add/edit/delete/view" functions also in a switch. When I try a $sub = $_GET['sub']; or $act = $_GET['act']; and use the 'sub/act' switch, it doesn't switch according to which 'sub/act' variable I call through the URL.

 

Is there another way to do this or am I going about this wrong via the switches? Hopefully my meaning is clear on this.

Thanks for any help.
