How to create dynamic subdomain using PHP and htaccess?

Question

I have one problem: I want to set up PHP and htaccess to make dynamic subdomains. And I can not figure out how. Currently my URL looks like this:

www.exemple.com/index.php?subdomain=mike&component=content&id=26&title=people-love-apps

I need it to look like this:

www.mike.exemple.com/content/26/people-love-apps.html

I know it can be done but I do not know a solution how to do it. Is very important to me with $ _GET [] functions to read parameter in the URL.

The problem is that users on my site make their web site and get a free domain (sub-domain) automatically. This should be automatic.

Thanks!

You can't make dynamic subdomains with .htaccess

You will need to configure the apache virtual host to accept requests for multiple domains

See the Apache documentation - Using Name Based Virtual Hosts

<VirtualHost *:80>
    ServerName www.example.com
    ServerAlias example.com *.example.com
    DocumentRoot /www/domain
</VirtualHost>

Adding the wildcard subdomain *.example.com, your PHP application will receive all requests for any domain below example.com, ie garbage.example.com, busted.example.com, llama.example.com, etc.

Creating Wildcard Sub Domain Using Apache VirtualHost

Multiple Domains to One Virtual Host | Wildcard Host (shared hosting)?

Apache default virtual host for multiple domains

At this point, your application will have to determine the validity of the subdomain and display the appropriate error for unknown subs.

From there, parse the domain for mike.

What about just using server aliases for each subdomain? – PassKit Jul 17 '13 at 18:07
Yes, but that is still vhost config, not `.htaccess` – user20232359723568423357842364 Jul 17 '13 at 18:13

Yes, the `*` in the server alias will accept ALL subdomains of the domain `example.com`. When the user is assigned the subdomain, the server will automatically respond on the subdomain and your application determines the validity of the subdomain. – user20232359723568423357842364 Jul 17 '13 at 19:53
In your vhost.conf add `ServerAlias *.example.com`. Then, your application can call `parse_url` http://us2.php.net/parse_url to get the requested subdomain – user20232359723568423357842364 Jul 17 '13 at 20:22

after create vshost do not forget to re-write the DNS table. at least if you are local, edit your /etc/hosts file and add the right entry there! – devasia2112 Apr 23 '14 at 22:07

OF COURSE you can interprete dynamic subdomains with htaccess. The following rule will solve the problem.

RewriteCond %{HTTP_HOST} www\.([^.]+)\.example\.com [NC]
RewriteRule ^/content/([0-9]+)/([a-zA-Z0-9_\-])\.html /index.php?subdomain=%1&component=content&id=$1&title=$2  [L]

so anyone visting

 www.mike.exemple.com/content/26/people-love-apps.html

will see the content of

www.exemple.com/index.php?subdomain=mike&component=content&id=26&title=people-love-apps

Tell me about something, do I need to configure apache for this? – Ivijan Stefan Stipić May 11 '15 at 12:14
No, you don't need any apache configuration. – tormuto May 13 '15 at 11:23
