I don't think doing everything in one place is a good way. That's why
they invented MVC :)
Anyways, one way would be:

Have a control url parameter, say, page.
Define an array like this:

$pages = array(
   "id1" => "class1",
   "id2" => "class2",
   ...
   "idN" => "classN"
);

Now have a script retrieve the url parameter, and instantiate the
respective class. Have all classes have a method to output content:

$id = $_REQUEST["page"];
$class = $pages[$id];
$obj = new $$class();
$obj->output();

The script will be your controller, the array will be the model, and the
classes will be the viewports, perhaps together with persistence layer.

This is, of course, overly simplified :)
