Need to rewrite question marks and equals signs in url

Rewritten my url. However I can still access rewritten urls with question marks and plus signs.

lovelakedistrict.com/lake-district-cottages/?cottages=2/
lovelakedistrict.com/lake-district-cottages/?cottages/2/
lovelakedistrict.com/lake-district-cottages/cottages/2/

The three urls above are the exact same page, I would like to properly re-write them so they redirect to the correct structure (the last url) to stop duplication of webpages.

Options +FollowSymlinks
Options +Indexes
RewriteEngine on

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /([^.#?\ ]+)\.php([#?][^\ ]*)?\ HTTP/

RewriteCond %1 !^include/
RewriteRule ^([^.]+)\.php$ /$1 [R=301,L]

Re开发者_JS百科writeCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ $1.php

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]

RewriteRule ^lake-district-cottages/cottages/([0-9]+) lake-district-cottages.php?cottages=$1

Try these rules:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^?\ ]*\?[^\ ]+
RewriteCond %{QUERY_STRING} ^/*([^=&]*[^=&/])/*(&+(.*))$
RewriteRule ^(.*[^/])/?$ /$1/%1/?%3 [N]

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^?\ ]*\?[^\ ]+
RewriteCond %{QUERY_STRING} ^/*([^=&]*[^=&/])/*$
RewriteRule ^(.*[^/])/?$ /$1/%1/?%4 [L,R=301]

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^?\ ]*\?[^\ ]+
RewriteCond %{QUERY_STRING} ^/*([^=&]*[^=&/])/*=/*([^&]*[^&/])/*(&+(.*))$
RewriteRule ^(.*[^/])/?$ /$1/%1/%2/?%4 [N]

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^?\ ]*\?[^\ ]+
RewriteCond %{QUERY_STRING} ^/*([^=&]*[^=&/])/*=/*([^&]*[^&/])/*$
RewriteRule ^(.*[^/])/?$ /$1/%1/%2/? [L,R=301]

But I guess the easiest would be to use a more powerful language than mod_rewrite like PHP:

$parts = explode('?', $_SERVER['REQUEST_URI'], 2);
if (count($parts) === 2) {
    $path = rtrim($parts[0], '/');
    parse_str($parts[1], $params);
    foreach ($params as $key => $value) {
        $path .= '/' . (($value === '') ? trim($key, '/') : trim($key, '/') . '/' . trim($value, '/'));
    }
    header('Location: http://example.com'.$path.'/', true, 301);
    exit;
}
