php - Move to https://www, when it is www or http:// or without www and http://?

Question

I am using Zend framework where i have nice looking url controllers. Following .htaccess is working but its making SEO to see us as four links for one page.

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R]

I need to do following fix using htaccess:

www.stackoverflow.com/nice-looking-url = https://www.stackoverflow.com/nice-looking-url

stackoverflow.com/nice-looking-url = https://www.stackoverflow.com/nice-looking-url

http://www.stackoverflow.com/nice-looking-url = https://www.stackoverflow.com/nice-looking-url

http://stackoverflow.com/nice-looking-url = https://www.stackoverflow.com/nice-looking-url

How to do it correctly using htaccess? so that above input urls are safely landing with https://www. in front always?

Have your full .htaccess like this:

RewriteEngine On

## add www and turn on https in same rule - main domain
RewriteCond %{HTTP_HOST} !^www. [NC,OR]
RewriteCond %{HTTPS} !on
RewriteCond %{HTTP_HOST} ^(?:www.)?(example.com)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [R=301,L,NE]

## turn on https in same rule - sub domain
RewriteCond %{HTTPS} !on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NE]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [L]

Make sure to use a new browser to test your changes to avoid old browser cache.
