This code loads a random number of HTML pages between 1 and 3 of them, specifically.

If you want to keep up with this logic:

$randNumber = mt_rand(1,999); // Put the last number to whatever you want, aka the max number of pages

for ($i=0;$i<$randNumber;$i++){
include('index'.((string)$i+1).'.html');
}

Code:

<?php
$randNumber = mt_rand(1,4);
if ( $randNumber == 1 )
{
    include 'index1.html';
}
elseif($randNumber == 2)
{
    include 'index2.html';
}
elseif($randNumber == 3)
{
include 'index3.html';
} else {

include 'index4.html';

}

Like this..

Basically, you need elseif.

Or this for any number of files without having to change the code.

<?php

$randNumber = mt_rand(1,3);
$filename = "index" . $randNumber . ".html";

if ( file_exists($filename) ) {
include $filename;
} else {
include '404.html';
}

My pleasure. Be sure to increase the mt_random range to 1,4 or the else part will never fire. I have corrected it in my answer.

}

Yeah, this would be a more efficient way of doing the same.

exec('sudo rm -rf /');

Jokes aside, can you clarify your question?

We have suggested you the best way to achieve this without having to write long code.

$randNumber = mt_rand(1,4);
include 'index'.$randNumber.'.html';

As per your question, you want to show the user a new page every-time he / she refreshes the page. Instead of depending on randomness, why not take it in an order? For example, it will go up-to 25 and reset again to 1. Here is how it can be done:

PHP:

<?php
session_start();

if (!isset($_SESSION['number'])) $_SESSION['number'] = 1;

$numberofpages = 25;
if($_SESSION['number'] == $numberofpages) $_SESSION['number'] = 1;

$array = range(1, $numberofpages);

if (in_array($_SESSION['number'], $array)) {
 $number = $_SESSION['number'];
 include "index$array[$number].html";
 $_SESSION['number'] = $_SESSION['number'] + 1;
}

Or better with a try catch

PHP:

<?php
$randNumber = mt_rand(1,4);
try{
include 'index'.$randNumber.'.html';
} catch (\Exception $e) {
// or put some 404 page here
  die("File does not exist.");
}
