How to let PHP to create subdomain automatically for each user?

Question

How do I create subdomain like http://user.mywebsite.com ? Do i have to access htaccess somehow? Is it actually simply possible to create it via pure php code or I need to u

Answer 1

First, you need to make sure your server is configured to allow wildcard subdomains. I achieved that in JustHost by creating a subomain manually named *. I also specified a folder called subdomains as the document root for wildcard subdomains. Add this to a .htaccess file in your subdomains folder:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.website\.com$
RewriteCond %{HTTP_HOST} ^(\w+)\.website\.com$
RewriteCond %{REQUEST_URI}:%1 !^/([^/]+)/([^:]*):\1
RewriteRule ^(.*)$ /%1/$1 [QSA]

Finally, all you need to do is create a folder in your subdomains folder, then place the subdomain's files in that directory.
