PHP: Redirect main domain to https://www, subdomain to https:// (without www)

Question

I want to modify a

php

-file to fulfill the following needs:

Main domain:

Redirect
http
to
https

Redirect
non-www
to
www

(for main domain,
www
is desired and should appear)

Subdomains:

Redirect
http
to
https

Redirect
www
to
non-www

(for subdomains,
www
is not desired and should not appear)

Comment: The subdomain has a completely different content than the main domain (could be private.website.com or cloud.website.com for example). It is not just a different language. Because of this, it seems not useful to create a internal forwarding via browser or CMS. It should be executed via

.hataccess

in best case.

Answer 1

If you are using php then you need to write some conditions And you didn't give any example of sub domain IF you are going to use sub domain like de.example.com , uk.example.com then you need to redirect with the help of browser language Or you can also do it with the help of visitors locations

just like

<?php    
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

if($lang=="de")
{

header('Location: https://de.example.com/');

}    
?>

IN that case you need to do the followings.

1) http to https

RewriteCond %{HTTPS} !=on

2) non-www to www

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

3) www to non-www

RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

PHP: Redirect main domain to https://www, subdomain to https:// (without www)
