Difference between including everything on index and showing all different pages?

As I am learning about including pages on the index instead of showing the pages itself, I have a hard time with it. So I was wondering something.

Is there any difference between using something like this to switch to show different pages on index.php:

switch($page) {
case 'page1':
    $pagefile='page1';
    break;
case 'page2':
    $pagefile='page2';
    break;
case 'page3':
    $pagefile='page3';
    break;
case 'page4':
    $pagefile='page4';
    break;
default:
    $pagefile='home';
}


require_once(''.$pagefile.'.php');

and just showing the php files itself? As in functionality or security etc?

U can use it for security i mean for example UR index.php be like this

include($_GET['page']."sec.php");

so the client won't see any page name only index.php?page=example and there are page name examplesec.php at UR folder so the client don't know the name of UR pages only see what ?page=the_page_name and U can change sec by and thing UR name or zzz

  • index.php will include another things at page like header , footer , side bar ... ect that will be at all pages

and U should use include_once so if there are any problem this will stop it

and for the pages is important use require_once so if the page not found the script will stop

Doing like this allows you to include some other thing in the same page and not have to repeat it on every page.

Let's say you have an header, a menu, your page, and the footer. Using this method you can do this :

<?php

$whiteList = array('index', 'page1', 'page2');

$page = in_array($_GET['page'], $whiteList) ? $_GET['page'] : 'index';

include('header.html');
include('menu.html');
include($page.'.php');
include('footer.html')

?>

EDIT : It's a very good thing to have an entry point to your application.

Let's say tomorrow you want to know how many total pages have been viewed, you can just add a counter in your index.php script (without repeating it in every other pages).

EDIT 2 : Note that the above code won't work everytime (there might be some error), but I won't spoil you the fun of finding out why. ;-)

Try it with this, it is smart to check the name because that way you protect sensitive files

if(in_array($page, ['page1', 'page2', 'page3', 'page4'])) {
    $pagefile = $page;
} else {
    $pagefile = 'home';
}

include($pagefile.'.php');
