What are the best practices for implementing mod_rewrite in PHP for URL rewriting?

When implementing mod_rewrite in PHP for URL rewriting, it is important to create a .htaccess file in the root directory of your website and configure it to redirect URLs using regular expressions. This allows you to create clean and user-friendly URLs that are easier to understand and navigate. Additionally, make sure to test your rewrite rules thoroughly to ensure they are functioning correctly.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [L,QSA]
