What are best practices for setting up URL redirection from index.html to index.php in PHP?

When setting up URL redirection from index.html to index.php in PHP, it is important to use a server-side redirect to ensure that the redirection is seamless and does not affect SEO. One common method is to use a .htaccess file to set up a 301 redirect from index.html to index.php.

// .htaccess file code
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/index.html$
RewriteRule ^(.*)$ /index.php [R=301,L]
