how to show the content of a wildcard subdomain? - php

Question

How can I do that when a user enters to a subdomain (I'll have wildcard subdomains), he will see what in the subfolder with the same name in the main domain? For example, if user will enter to works.domain.com, I want him to see what's in www.domain.com/works.
Here is my approach:
I have created a wildcard subdomain like *.domain.com
Created some subdomain into the wildcard directory with a index.php file as I can check preferences other information about this store -> see:
Now my intention is to provide the user what they ask for in the url
This code is written in wildcard/index.php file
<?php
//Get the store name from url
$host = $_SERVER['HTTP_HOST'];
$url = explode('.', $host)[0];
//Find the store name is it available in the database
$db = new database;
$qri = $db->query("SELECT * FROM store_info WHERE store_name='$url'");
$count = mysqli_num_rows($qri);
//If it returns true then show the reuquested store data
if($count != 0){
*I want to show here the folder data that requested in the url*
}else{
echo 'Store Not found';
}
Now my question is:
Is it the right approach to do it,so how can I show the requested folder data?

You can configure NGINX in front of your PHP server to route to particular directories with the following configuration (not tested). Configuring this in NGINX would be efficient than configuring this in PHP.
server {
server_name ~^(?<sub>[a-zA-Z0-9-]+)\.domain\.com$; # will cause the sub-domain to be placed in $sub
return 301 "http://testsite.net/${sub}${uri}";
}
