.htaccess rewrite PHP $_GET multiple pages

.htaccess

    RewriteEngine On
    RewriteRule register index.php?mode=register
    RewriteRule login index.php?mode=login

index.php

        if ( isset ( $_GET['mode']) && ( $_GET['mode'] == 'register' ) ) {

        include('includes/register.php');
    } elseif ( isset ( $_GET['mode']) && ( $_GET['mode'] == 'login' ) ) {
        include('includes/login.php');  
    }
    ?>

This is my current method (thanks to @TROODON).

Is there an easier way, maybe using key-value arrays to store all the possibilities for the various pages that index.php will call?

Thanks

For your .htaccess you can do this:

RewriteEngine ON

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?mode=$1 [L,QSA]

However, don't change your PHP code to just include whatever you are getting from $_GET['mode']! This will allow users to include at will.

You could adjust your PHP code like so:

$pages = array("register" => "includes/register.php",
               "login"    => "includes/login.php");

if(isset($_GET['mode']) && $pages[$_GET['mode']])

    include $pages[$_GET['mode']];

PS: The two RewriteCond's make sure the url is not an existing file or folder (i.e. if you have a folder images then site.com/images will still go to that folder instead of index.php?mode=images.
