How to make a subdomain like sa.domain.com and display specific data on it ? PHP

@ebrahemsamer if you have multiple subdomains you can point them all to the same root directory and then use

$_SERVER['HTTP_HOST']

to determine which host is being accessed and filter your products that way.

If its laravel, then there are more elegant solutions.

Laravel do have Subdomain Routing https://laravel.com/docs/8.x/routing#route-group-subdomain-routing

But, creating a new or updating existing subdomain will involve DNS record changes and it will take from hour up to 72 hours to propagation to all the world...

i think i would prefer to use middleware to update the region/country and store it in session or somewhere to filter the data without touching the dns part...

Maybe I am missing the question, but it seems as if you could have the domains point/use the same database, each domain defining the specific qualification(s) you want.

Define the qualification's value in either the .env file OR in the config/app.php file (preferred choice) This would allow you to specify the qualification for each of your domains you currently have and may add in the future.

And, for the domains which would not have any specific qualification(s) you could have it defined as "1=1" in .env or config/app.php.

@phread @siangboon the OP said its PHP Native, not Laravel.

overlook the last 2 words...

still, allow user to select their own region/country may be more preferable for me...

But when I redirect subdomains to the original one, the url changes.... @automica

@ebrahemsamer don't redirect the subdomains. Set them to point to the same document root as your primary domain.

eg

<VirtualHost www.company.com>
DocumentRoot /path/to/main/documentroot
    ServerName site1.company.com
</VirtualHost>

<VirtualHost subdomain1.company.com>
DocumentRoot /path/to/main/documentroot
    ServerName subdomain1.company.com
</VirtualHost>

<VirtualHost subdomain2.company.com>
DocumentRoot /path/to/main/documentroot
    ServerName subdomain2.company.com
</VirtualHost>
