Eg, for a website I have, website.com/abcd, I need to extract the 'abcd' variable and store in a database. If a user visits website.com/abcd it redirects to a 404 page. I have been tinkering with .htaccess but not getting anywhere.
Pop the below into a .htaccess file...
<IfModule mod_rewrite.c>
RewriteEngine on
Options +FollowSymlinks
Options -Indexes
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteBase /
RewriteRule . /index.php [L]
</IfModule>
... then use <?php print_r($_SERVER);?> to show variables that your server will let you use.
The above htaccess code is pretty basic; if the file/directory that's being requested doesn't physically exist, requests will be redirected to ./index.php.
