To test whether mod_rewrite is working, create a .htaccess file inside your webroot as follows:

RewriteEngine on
RewriteBase /
RewriteRule ^test.php$ rewrite.php

Create file test.php in the same directory with the following code:

echo 'mod_rewrite is not working';

Create file mod_rewrite.php in the same directory with the following code:

echo 'mod_rewrite is working';
