Check my .htaccess code please

Hi everyone,

I have added an SSL certificate and would like to have www in front of my domain, please can you check my current .htaccess code and let me know if I should make some changes:

Code:

RewriteEngine On

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.example.com/$1 [R=301,L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|public|images|robots\.txt|css)
RewriteRule ^(.*)$ index.php/$1 [L]

Thanks!
