htaccess for shortened URL - php

Question

I'm working on a URL shortener script.
My script generates a link like http://127.0.0.1:1337/urlshortener/v5tjp.
v5tjp is a random value, generated by a script.
My script's logic is that I input an URL, then PHP takes it, generates a random value (with the length taken also from the SQL database), then inserts the long url and the short url in the database.
Where I'm stuck: I need to create a .htaccess file to redirect the visitor to redirect.php, where I have the redirect script.
This is the redirect.php file:
<?php
include ('connect.php');
$decode = mysql_real_escape_string($_GET['decode']);
$sql = 'SELECT * FROM urls WHERE short_code="$decode"';
$result = mysql_query($sql);
if (isset($_GET['url_token'])){
$urlId=$_GET['url_token'];
$query = "SELECT * FROM urls WHERE short_code=".$urlId." LIMIT 1";
$redirect = mysql_query($query);
if(mysql_num_rows($redirect)) {
$row = mysql_fetch_assoc($redirect);
$url = $row['long_url'];
header('Location: http://'.$url);
}
echo 'Bad URL!';
exit();
}
while($row = mysql_fetch_array($result))
{
$res=$row['long_url'];
header("location:".$res);
}
This is the .htaccess file I've made:
RewriteEngine On
RewriteRle ^$ index.php [L]
RewriteCond %(REQUEST_FILENAME) !-f
RewriteRule ^(.*)$ redirect.php?url_token=$1 [L]
But for some reason it's not working. I'm running my script with XAMPP.

Answer 1

RewriteRule ^$ index.php [L]
You missed a 'u'.

Answer 2

Try this code:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteRle ^$ /index.php [L]
RewriteCond %(REQUEST_FILENAME) !-f
RewriteRule ^urlshortener/(.*)$ /redirect.php?url_token=$1 [L,QSA,NC]
