title: How to match dynamic sub-domain alias to sub-folder on apache server
body: <p>I am currently developing a SaaS web based project using PHP which requires users to have unique sub-domains to use the application.</p>
  
  <p>I am done configuring the server with wildcards: Eg. <code>user.example.com</code> ==> <code>*.example.com</code>. The application creates a subfolder for the user under <code>/var/www/html/</code> with the name of the user Eg. <code>user.example.com</code> would be in <code>/var/www/html/user/</code>.</p>
  
  <p>I am stuck on getting the user's link without the base folder such as <code>user.example.com</code> to point to <code>/var/www/html/user/</code> without having to include <code>http://user.example.com/user</code>.</p>
  
  <p>I have tried virtual host and aliases but it seems like I have to manually assign the variable which is not applicable for the project.</p>
  
  <p>I just need the subdomains to point to their respective subfolders.</p>
  
  <p>My apache config file</p>
  
  <pre><code>&lt;VirtualHost *:80&gt;
          # The ServerName directive sets the request scheme, hostname and port that
          # the server uses to identify itself. This is used when creating
          # redirection URLs. In the context of virtual hosts, the ServerName
          # specifies what hostname must appear in the request's Host: header to
          # match this virtual host. For the default virtual host (this file) this
          # value is not decisive as it is used as a last resort host regardless.
          # However, you must set it for any further virtual host explicitly.
          #ServerName www.example.com
          ServerAdmin admin@xxxxxxx.tdl
          DocumentRoot /var/www/html/%1/
          # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
          # error, crit, alert, emerg.
          # It is also possible to configure the loglevel for particular
          # modules, e.g.
          #LogLevel info ssl:warn
          ErrorLog ${APACHE_LOG_DIR}/error.log
          CustomLog ${APACHE_LOG_DIR}/access.log combined
          # For most configuration files from conf-available/, which are
          # enabled or disabled at a global level, it is possible to
          # include a line for only one particular virtual host. For example the
          # following line enables the CGI configuration for this host only
          # after it has been globally disabled with "a2disconf".
          #Include conf-available/serve-cgi-bin.conf
          ErrorDocument 404 /error_404.html
  &lt;/VirtualHost&gt;
