How to create dynamic subdomain using PHP and htaccess?
提问by Ivijan Stefan Stipi?
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:
我有一个问题：我想设置 PHP 和 htaccess 来制作动态子域。我不知道如何。目前我的网址如下所示：
www.exemple.com/index.php?subdomain=mike&component=content&id=26&title=people-love-apps
I need it to look like this:
我需要它看起来像这样：
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.
我知道可以做到，但我不知道如何解决。用 $_GET[] 函数读取 URL 中的参数对我来说非常重要。
The problem is that users on my site make their web site and get a free domain (sub-domain) automatically. This should be automatic.
问题是我网站上的用户创建他们的网站并自动获得免费域（子域）。这应该是自动的。
Thanks!
谢谢！

You can't makedynamic subdomains with .htaccess
你不能用动态子域.htaccess
You will need to configure the apache virtual host to accept requests for multiple domains
您将需要配置 apache 虚拟主机以接受对多个域的请求
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.
添加通配符子域名*.example.com，你的PHP应用程序将获得以下任意站点的所有请求example.com，即garbage.example.com，busted.example.com，llama.example.com等等。
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.
此时，您的应用程序必须确定子域的有效性并为未知子域显示相应的错误。
From there, parse the domain for mike.
从那里，解析域的mike.

OF COURSE you can interprete dynamic subdomains with htaccess. The following rule will solve the problem.
当然，您可以使用 htaccess 来解释动态子域。下面的规则将解决这个问题。
RewriteCond %{HTTP_HOST} www\.([^.]+)\.example\.com [NC]
RewriteRule ^/content/([0-9]+)/([a-zA-Z0-9_\-])\.html /index.php?subdomain=%1&component=content&id=&title= [L]
so anyone visting
所以任何人访问
www.mike.exemple.com/content/26/people-love-apps.html
will see the content of
会看到内容
www.exemple.com/index.php?subdomain=mike&component=content&id=26&title=people-love-apps
