In PHP, what is the recommended approach for redirecting all non-static resources to a single index.php file for processing?

When redirecting all non-static resources to a single index.php file for processing in PHP, the recommended approach is to use mod_rewrite rules in the .htaccess file. This allows you to rewrite URLs to point to the index.php file while preserving the original request path. This way, all requests can be handled by a single entry point for processing and routing.

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