Php Multiple Pages Per One File

[gmz1023]

Hey y'all,i'm working on a website right now and i have a quick question about PHP.so lets say i have a code like thisCODE<?php$cmd = $_GET['cmd'];switch($cmd){case "page1":@include('page1.php');break;case "page2":@include('page2.php');break;case "page3":@include('page3.php');break;}?>and i want to make it so that instead of having to program the codes for the websites in manually it would just go off of the link it self, how would i do that?

$cmd = some_sanitize_function($_GET['cmd']);include($cmd.php);
