Laravel Multi Tenant considers www part as subdomain - php

Question

I am building a multi tenant system in laravel and each subdomain is saved in database. When a subdomain in visited, it is checked from the database either it exists or not, if it doesn't exists then abort(403) is called. Following is the way:
Routes/web.php
Route::group(array('domain' => '{subdomain}.example.com', 'middleware' => ['Subdomain']), function () {
Route::get('/', 'IndexController#index');
}
Middleware/Subdomain.php
public function handle($request, Closure $next)
{
if(Subdomains::where('subdomain', $request->subdomain)->count()==0){
return abort(403);
}else{
return $next($request);
}
}
But when I visit www.example.com, then www is also considered as subdomain and checked from database, since it doesn't exist in database and abort(403) is also called for it. In short my website is not visited with www.example.com URL.
Is there any way to differentiate www form other subdomains in this Laravel multi tenancy system or any way to handle this thing?

Answer 1

Just use an if statement to check if the subdomain queried is www
public function handle($request, Closure $next)
{
if($request->subdomain != 'www') {
if(Subdomains::where('subdomain', $request->subdomain)->count()==0){
return abort(403);
}else{
return $next($request);
}
}
}
Also in your .htaccess, remove www from the domain name
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.example.com$ [NC]
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]
