.htaccess remove index.php and hide parameter key from URLs

Question

I have the following URL

www.example.com/index.php?tag= xxx

I want to make it like the following using .htaccess

www.example.com/xxx

I done it with this code:

 Options +FollowSymLinks -MultiViews
    # Turn mod_rewrite on
    RewriteEngine On
    RewriteBase /

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

SO if I input this URL:

www.example.com/index.php?tag=1000

it be redirect to:

www.example.com/?tag=1000

---

if: www.example.com/1000 it works!

So I have dublicate URL and it's not good for seo.

How can redirect www.example.com/index.php?tag=1000 to www.example.com/1000

Answer 1

use this code for .htaccess file

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

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

you index.php code will be

<?php 
echo $_REQUEST['key'];  
?>

then call http://sitename.com/1000

output will be :1000
